Hello, and thank you for visiting Office Recovery and Restoration Dot.Com!
Based in Ikebukuro, Toshima Ward, Tokyo, we specialize in interior finishing and original state restoration work for offices and commercial properties across Japan.
In this article, we’ll introduce and explain the construction method of gypsum board, a material widely used in office ceilings and walls.
We’ve covered gypsum board several times in past articles.
However, we realized we haven’t gone into detail about how it’s actually installed.
Since gypsum board is usually hidden behind wallpaper or paint, its installation process isn’t often visible — and therefore not widely known.
We hope this article gives you a better understanding of interior board materials and how they’re used in construction.
Before we dive into the installation process, let’s take a quick look at the key features that make gypsum board such a popular choice for interior construction.
Among all board materials, gypsum board is the most widely used in both residential and commercial buildings. Its key advantages include:
Thanks to these benefits — especially its affordability and fireproof qualities — gypsum board has largely replaced wood-based materials in ceiling and wall construction.
There are also several types of gypsum board available, in addition to the standard version — including boards with enhanced strength, improved fire resistance, and better moisture resistance.
These products also come in a variety of thicknesses, typically ranging from 9.5 mm to 21 mm, depending on their intended use.
One of the most widely used options is the “Tiger Board”, manufactured by Yoshino Gypsum Co., Ltd., which is available in three standard thicknesses: 9.5 mm, 12.5 mm, and 15 mm.
Because gypsum board is relatively thin, it requires a solid base for installation. There are four main types of base materials:

While rarely used in offices or retail spaces, wooden framework is still occasionally found in apartments and detached houses.
However, it’s important to note that not all wooden buildings use wooden frameworks.
In fact, some wooden houses may use LGS (light gauge steel) for interior partition walls.
Likewise, wooden frameworks can sometimes be used even in concrete structures when specific design or construction needs arise.
Gypsum boards are attached to wooden frameworks using nails or screws, and the length of the fastener must match the thickness of the board.
Using the wrong size can lead to cracking or reduced structural strength, increasing the risk of poor workmanship or even safety hazards.
This photo shows the installation phase of LGS framing at a construction site for an educational facility.
LGS frameworks have now become the industry standard in interior construction, surpassing wooden frameworks in both frequency and volume of use.
In fact, in most modern offices, shops, and commercial spaces, LGS is the go-to choice for partition walls and ceilings.
Gypsum board is attached to the LGS structure using self-drilling screws. As with wooden frameworks, the screw length and spacing must be carefully selected based on the board thickness.
If these installation standards are not followed, it can lead to serious issues such as board cracking, insufficient support, or even falling materials, which may result in accidents or costly rework.
This photo shows the process of applying GL bond using the GL construction method.
The colored surface on the concrete is due to sprayed-on thermal insulation.
When attaching gypsum board directly to concrete surfaces, screws or nails cannot be used.
In many cases, an LGS framework is first installed to support the board, but when space, budget, or construction time is limited, the GL (Gypsum Lining) construction method is used instead.
In this method, the surface is thoroughly cleaned, and a primer is applied to improve adhesion.
A special adhesive called GL bond is mixed on-site with water, then applied in dabs at regular intervals.
The gypsum board is then pressed onto the adhesive and left to set.
This technique leaves distinct round adhesive marks behind the board, which are often visible during demolition.
Because it relies entirely on adhesive, this method is only suitable for walls — not ceilings — due to gravity and safety concerns.
To increase wall strength, a second layer of gypsum board is sometimes installed over an existing one.
In such cases, the board seams are staggered so that the joints of the second layer do not align with those of the first.
Rather than using screws, this method often employs a combination of white construction adhesive and a tacker (a heavy-duty stapler used for temporary fixing).
The tacker holds the board in place until the adhesive dries, which provides the main holding force.
This method is preferred because it improves installation efficiency and reduces labor time.
The amount of adhesive and the number of staples are predetermined.
Skilled installers ensure that the final surface is smooth, with no visible bumps or unevenness.
Gypsum boards are generally rectangular, and the way they’re laid out depends on the site conditions and the installer’s preferences.
In most cases, installers try to use full boards as much as possible, cutting only at the edges.
This approach helps reduce labor and material waste.
In standard applications, gypsum boards are later covered with decorative finishes such as wallpaper or paint, so the layout is rarely visible.
However, in cases like decorative ceiling boards (e.g., Gyptone)—often used in schools or hospitals—the visible layout becomes part of the finished design, so the way the boards are assigned and installed is clearly noticeable.
Here are two common layout styles used in decorative ceiling installations.
⓵. Brick Pattern Installation
This photo shows decorative gypsum boards being installed on the ceiling of a hospital.
The joints are arranged in an alternating pattern, known as the brick pattern.
This photo shows decorative gypsum boards being installed on the ceiling of a hospital.
The boards are laid out using the brick pattern, where the joints are staggered in an alternating fashion.
As the name suggests, each board is offset by half the length of the long side, creating a layout similar to traditional brickwork.
This method is also known as staggered layout, running bond, or horse pattern.
⓶．Straight Joint Pattern
This photo shows decorative gypsum boards being installed in a straight joint pattern at another construction site.
In contrast to the brick pattern, the straight joint layout aligns the board seams in a continuous vertical and horizontal grid.
This method is often used when working with square or uniformly sized boards, especially in layouts where cuts are minimized and a clean, symmetrical appearance is preferred.
final
We’ve just introduced how gypsum board is installed — a material that supports most office ceilings and walls today.
Gypsum board has become the standard in modern interiors, replacing traditional materials like plywood and solid wood.
It is typically fixed using screws or nails to match the base structure, such as light gauge steel (LGS) or wooden framework.
Since the surface is usually finished with wallpaper or paint, it’s important to install gypsum boards quickly and precisely to avoid unevenness.
While gypsum board is usually hidden under finishing materials, except for decorative panels, it is widely used across most ceilings and walls in today’s office interiors.
As the moving season approaches, we often receive inquiries about reapplying or replacing gypsum board after tenants move out.

～～～～～～～～～～～～～INTERIOR DECORATIVE WORK CONTRACTOR～～～～～～～～～～～～～
This topic is also explained in detail in our Japanese-language blog.
Hello, everyone！ We here are Office recovery and restoration Dot.Com. website.
Having been setting up our company office at Ikebukuro, Toshima ward, Tokyo, we are an interior decorative construction work contractor, mainly taking charge of Interior decorative finishing work・Original state recovery and restoration work in all over Japan.
Concerning office interior decoration, please talk and/or take counsel with us on anything light heartedly.
Today, we are introducing and explaining『niche』.
In the first place, it seems that you may not get used to hear the word niche.
Often used implications for the business are,「Niche industry」and so on.
All in all, it is of-the-niche industry, isn’t it?
What is often seen in Japan is katakana notation of「ニッチ」.
However, originally, it is written as an English word of「niche」.
It seems that it mainly means「niche」,「ecological system」,「shelter」.
It seems that its implications and usages are different, according to the fields and scenes.
This time, we are explaining「niche」which means as a terminology of architecture.
The following is a reference from kotobank.jp website.
In Western style construction, a concave part made by hollowing out a thick wall.
A carved statue, flower vase, and so on are placed. Niche
Reference: What is niche? The meaning and usage-kotobank.jp internet website
Niche is a space which was made by hollowing out a wall to 凹 shape.
By utilizing this 凹shape, we can use it as the interior accent and the storage space.
Generally, by using the wall thickness of niche and let it have profoundness, we make a space for storing goods and/or decorating it.
Usually, it is made by letting the wall cave in about 5～10cm. However, the profoundness and the size can be adjusted according to the installing place and the purpose.
Basically, generally, niche is a space partially hollowed out by a wall. It is generally made in a structural stable partial place.
There may be those who tend to wonder if it is OK to hollow out a wall?
Usually, when we will make niche, we surely take care of the following points and make one:
When installing niche, we select a place which does not influence the building strength.
For example, by avoiding to install in bearing wall and important supporting structure, we avoid structural problems.
As for the wall which is supporting a housing structure, if we concave it, chances are that the entire housing strength may be influenced.
What kind of wall is appropriate for it? If we give an example, it is:
A regular wall such as partition wall and so on are the most appropriate to make niche.
As it does not support the housing structure, it is relatively easy to be able to concave it.
If it is piped and/or wired in the wall, it is necessary to avoid them to make niche.
In order to confirm inside the wall, it is convenient to confirm the drawing data and to use the special detector.
Inside of niche, it is possible to apply the materials and finishing according to the design and the usage.
As the making method of the wall is the same as usual one, it is possible to do its finishing of interior decoration widely.
However, it may come to change according to the wall groundwork materials too.
Various finishings are possible as above.
In order to highlight niche, it is also possible to install a light in it.
For example, indirect light, spot light, and so on, these lights are used to match the design.
Niche is often used as a decorative shelf, and it can be used for various usages.
If we go on raising concrete examples, there are following usages:
・Storage space: It can be used as a shelf for storing books, magazines, CDs, and so on.
・Decorative shelf: It can be used for a space to decorate art works, family pictures, memorabilia, and so on.
・Interior accent: In order to let the wall surface have alteration, a decorative niche is placed sometimes. Particularly, by combining with indirect light, it is possible to add accent to the entire wall design, which will show a stylish feeling.
・Equipment storage: There is a niche for storing remote controller, switch, interphone, and so on too. It will become a neat appearance impression.

Referring to the above, we think we would like to introduce and explain a niche work in the toilet interior decoration this time.
The construction site example which we executed this time is, an office toilet interior decorative finishing in a sheet metal factory, located in Odawara city, Kanagawa prefecture.
Niche wall, sticking so-called decorative cloth
Niche finishing result
Indirect light is also applied in the niche, so there is a stylish feeling.
We executed LGS(=light gauge steel)・PB(=plaster board) construction on the groundwork, made a hollow in the niche wall area, applied so-called decorative cloth, and installed an indirect light in the niche ceiling area, which has made a stylish feeling.
As the toilet interior decoration this time is a work with niche, it has become a stylish and spacious space.
Niche designing and interior decorative finishing greatly influence the entire r room feeling.
How to finish niche is important for selecting its method, according to the room style and the purpose.
Please try to make up a stylish niche with reference to this blog by all means!
By utilizing niche, we are sure that the interior decoration will be further more charming.

Japanese Blog ↓
Hello, everyone！ We here are Office recovery and restoration Dot.Com. website, a personnel in charge.
We have been setting up our company office at Ikebukuro, Toshima ward, Tokyo, and we are an interior decorative work contractor, mainly taking charge of construction of Interior decorative finishing work・original state recovery and restoration work in all over Japan.
This time, as one of Terminology series after a certain time, by going back to the basic, we are introducing and explaining『light gage steel』once again.
I briefly do the roundup in my own way, then I am going to introduce it to you based on the construction pictures.
As this article is easy to read through, please browse it light heartedly.
Light gauge steel (LGS) is a construction material made by cold forming of thin steel.
It is widely used as a structural material of architecture.
While its weight is light, it has high strength too.
So, it is variously used in the places such as housings, commercial facilities, industrial use buildings, and so on.
The silver-colored material installed in the ceiling and wall is LGS.
The silver-colored material installed in the ceiling and wall is LGS.
「Light weight」-ness also in its term name
Compared with the conventional steel frame, it is very light.
As its transportation and construction are easy to do, it is used in a lot of construction sites.
※Conversation only here confidentially:
It is lighter than other conventional steel frames.
But, when we are asked if it is possible even for a female also can easily hold it, we will answer that, although it is relatively lighter than other construction materials.
But, whether even a female feels that she 「can hold it easily or not」, it depends on the size and length of the steel frame, and each person’s physical strength too.
LGS pillars and beams change the weights according to the cross-section area and length.
Generally, the weight of a piece of LGS steel frame varies from about a few kilograms to a few tens of kilograms.
However, it is also important in the lifting up pose and holding way.
If it is small sized, it may be easy to hold it.
But, if it is long and thick, the weight balance is sometimes difficult to keep it.
Chances are that it may be difficult only for one person to move it.
As the safety side is considered, moving it by plural persons and using appropriate equipment are recommended.
So, in the case of only one person will move or make landing it, let’s be careful!
While its weight is light, as it has very high strength too, it is suitable for a building where earthquake resistant property and durability are required.
If we briefly explain tensile strength of steel used for LGS, it seems that「Even if we hang the steel of every 1 square millimeter cross-section area like thin needle of it(=structural steel) on the steel frame of the weight about 40～55 kilograms, it will not be broken.」.
Steel material is resistant to corrosion and insect damage.
So, it will exhibit its stable performance for a long time.
As for its durability, it is usually said that the duration of life is 50～100 years.
In the case of appropriate designing and protection are applied, it is possible to use it within this range without any problems.
However, if the problems of rust and/or corrosion go fast, depending on its maintenance, the durability of life may be shortened sometimes too.
For your reference, in the case of using it as a building interior decorative groundwork, as the groundwork of a ceiling and wall, compared with wooden material, it is lighter and has more strength too.
Therefore, it is recommendable to use it, as it has a high long-term durability.
As abovementioned, LGS is light, and has high strength as well.
As you can choose one from various cross-section shape type, such as C type, L type, and so on, it is a material whose freedom of designing is very high.
As you can take column interval wider than wooden material, you can secure a large space. An open and few pillar design is possible.
As it is also easy to process it in the work site, and fine adjustment and complex shape corresponding can be easy to do too, it is suitable for curvilinear design and special interior decoration too.
In addition, as it is possible to flexibly correspond to extension, reconstruction, and renovation, it can be easily correspond to change the design in the future too.
As it is used in various buildings such as housings, commercial facilities, factories, and so on, LGS is an excellent construction material which will realize free design for wide usages.
As the reason of its high earthquake resistant property, you can also use it in earthquake frequently striking areas with ease too.
And, also as for fire breakout, it has a certain fireproofing property.
The reason why the earthquake resistant property is high is, as its name suggests, LGS is light. So, as it can control the weight of entire building, when earthquake strikes, the burden of earthquake shaking becomes small.
In addition, as steel frame has strength and tenderness together too, it also flexibly corresponds to earthquake power.
So, the damage and injury can be controlled to minimum.
We are introducing and explaining a part of construction site example.
LGS is being widely applied to the following architecture.
Housing apartment
LGS is being used as a structural material of the living space such as in single-family dwellings.
It ts light and has highly strength, multiple dwelling, and so on.
As it is light and has high strength, it is the most suitable to the building where earthquake resistant property and durability are required.
It is the work of a tenant in a commercial facility.
It is the state of making the groundwork of curved wall.
By using R processed runner (rounding corner processing) , it is possible to make a built-in gypsum board wall which has designability.
LGS is a very excellent construction material which is light, and has high strength and durability.
The freedom of designing is high, so, it is being widely used for various buildings, such as housings, commercial facilities, and so on.
As it is also excellent in earthquake resistant property and fireproofing property, it can secure safety, more and more demands are being expected continuously.
Our company is taking charge of a lot of interior decorative work and original state recovery and restoration work by using LGS.
If you are interested in these, please give us your inquiry from the following「inquiry」light heartedly!

What we are introducing and explaining today is,
「Safety countermeasure when executing work」
In order to proceed work safely, various factors are important.
The points of safety countermeasure of its elementary contents compiled are as follows:
安全第一に
In the construction site, it is important to make a plan of safety and sanitation management in advance, and to execute it thoroughly.
When planning it, let’s include countermeasures for emergency situation and confirming necessary safety equipment.
It is indispensable to check out the equipment and tools for using the construction regularly.
By using them in normal situation, it is possible to protect from an accident and a trouble during the work operation before happening.
When operating at the high-place, it is particularly important to take safety countermeasure.
By wearing appropriate safety belt, installing handrail and so on, let’s do not neglect countermeasures in advance.
Upon proceeding the construction, let’s confirm the using construction method and the materials.
Selecting the right construction method will lead to protect from ocuring an accident.
Let’s carry out training, so that all the staff work workers can predict possible danger and can appropriately cope with it.
Quick decision will defend from an accident before happening.
If the temperature condition changes, it is necessary to adopt a measure to correspond to it.
Let’s try best to take suitable measures against rain and wind.
By doing five-point thoroughness of 5S, namely sorting・setting-in-order・shining・standardizing・sustaining the discipline, we neaten the environment of work operation.
By doing these, we can expect to go up efficiency and defending from an accident.
By sharing unsafe incidents among staff workers, and sharing the information, we will keep the safe environment.
By grasping health situation of staff workers, and securing suitable rest and nutrition, we will defend an accident suffering from ill health.
Let’s carry out basic education on safety to all of the staff workers.
By sharing right knowledge, it is possible to minimize outbreak of the danger.
Smooth communication in the work operation site is inevitable for preventing an accident in advance.
Let’s care for sharing the information and cooperation.
If a staff worker’s accident occurs, clarifying the process for taking quick and suitable countermeasure and all of the staff workers grasp it in advance are important.
By observing all of these above points, it is possible to secure the safety in the construction site, and protect staff workers’ health.
Let’s consider to take enough safety countermeasure in order to proceed the construction smoothly.
For construction site safety, it is inevitable to take planned countermeasure and cooperation of all of the staff workers.
Let’s always pay attention to safety and have a posture to be able to cope with a predictable risk.
Maintaining safe work operation environment not only directly links to success of the project, but also links to the health and happiness of all the persons connected.
Let’s share the thought of safety first, and always try best to prevent from danger before happening every day.
Safe construction will lead to reliance and high quality, and will make a part of establishing better work environment.

We are introducing and explaining gypsum board in the blog this time.
Nowadays, as one of the indispensable materials for architectural interior decorative work, we thought we would like to research gypsum board more in detail, so we coordinated the following article.
Picture quoted from Yoshino Gypsum Co. Ltd.
Picture quoted from Yoshino Gypsum Co. Ltd.
Gypsum board is a kind of construction material used for wall and ceiling finishing, and reinforcement in the construction and interior decorative work.
Generally, it is also called as「dry wall」or「gypu board」.
Gypsum board has different common names in countries and areas.
As there is a possibility of difference in the areas, when confirming a name used in particular area, kindly try to check its own naming.
●Dry wall
In many countries such as USA, Canada and others, it is called as「dry wall」.
This name derives from dry type construction process of gypsum board.
●Gypsum board
「Gypsum board」is related to the main component of gypsum.
This name is general in the world.
●Plaster board
It is called 「plaster board」in England and some English speaking countries.
This name derives from the fact that plaster was used for wall finishing before.
●Wall board
It is called「wall board」in some areas.
This name is related to be used for wall finishing material.
●Board rock
It is sometimes called「board rock」in Japan and some countries.
This name is a common general naming for pointing gypsum board.
●Construction plaster board
It is also called「construction plaster board」in some areas.
It is a name often used in the construction industry.
Firstly, the main component of gypsum board is, a mineral raw material (calcium sulfate dehydrate) called gypsum.
This gypsum is the main material of gypsum board. By hardening it, it constitutes solid board shaped structure.
Its structure consists of two paper sheets sandwiched gypsum center layer usually.
Generally, its thicknesses are various sizes from 1/4 inch to 5/8 inch.
Main general size is 4×8 feet.
Gypsum board is used for wall and ceiling interior decorative material. In order to finish the room space inside, it plays a role of base material for painting and sticking on tyles, wall papers and so on.
In addition, it is also used for partition wall, sound insulating wall, fire resisting wall and other structure construction.
Characteristic:
Gypsum board is relatively light and easy to handle, so it is being generally used in the interior decorative work very much.
It is possible to use various kinds of gypsum board in the market, so it is important to select appropriate kind according to the content of interior decorative work.
1.Interior decorative finishing of the wall and ceiling
Gypsum board is the most used for the interior decorative finishing of wall and ceiling generally.
It is used to combine with joint compound, and makes smooth surface.
By doing this, it is ready to fit wall paper, other decorative material and/or to paint.
2.Screening
Gypsum board is used for hiding electricity wiring, piping, heat insulating material and so on in the wall.
It is possible to place wiring and piping without opening the wall, so it provides functional screening, while keeping beautiful sight.
3.Fire resisting property
Some gypsum board has fire resisting property, so it plays a role of delaying fire expansion.
This is important for commercial facility, multi-family residence and so on.
Using example: Fire resisting gypsum board is used at the office building partition wall, so it is securing safety to prepare for fire breakout in case.
4.Sound insulating property
Gypsum board excels in sound insulating property. By using it at the wall or ceiling in interior decoration, sound transmission is controlled. This characteristic is suitable for using it at the apartment and office building.
Actual usage: On the wall of art studio, a kind of gypsum board of high sound insulating property is installed, so noisy sound outside is controlled as much as possible, and is providing creative environment.
5.Light weight property and easy handling
Gypsum board is light, so handling it is easy. For this reason, quick progress of interior decorative work process becomes possible.
Example: In DIY(do-it-yourself), installing gypsum board and handling are easy, so new wall surface can be made quickly.
Because of its various usage and excellent characteristics, gypsum board is one of the indispensable construction materials in the modern interior decorative industry.
From interior decorative finishing up to screening, fire resisting property, and sound insulating property, it is bringing into high effectiveness by various usages.
When planning interior decorative work, considering gypsum board utilizing method is an important process.
Chances are that the ways of using gypsum board are different according to work kinds and requirements.
In interior decorative work of big scale decorative renovation work or that with special requirement, it is important to receive an advice from its specialist.

Hello, everyone！ We here are Office recovery and restoration Dot.Com. website.
We are taking charge of「Interior decorative finishing work」「Original state recovery and restoration work」mainly in Ikebukuro at the midpoint, and in all over Kanto district for you.
This time, we are explaining a theme of,
What is OA floor? What kind of merits・demerits are there, and how is it constructed?
If you are an office worker, you may sometimes hear of the theme, however, on OA floor, if you actually asked about it, it may be hard to precisely answer that at once, so we are roughly explaining it.

The picture quoted from Japan Free) access floor Association website. The official website is here.
In the office, OA floor is, mainly pointed to be, so-called double flooring, which is, in order to make cable wiring such as LAN, power source and others smooth, for providing space passing wiring on the existing floor and executing work on it.
As a general name, it is also called「free access floor」and so on.
It was only used for some limited placed at server room, clean room and so on before. However, in the modern days when IT introduction advanced, it is also used in almost all the general offices.
Main merits of OA floor are as follows:
There are above features.
On the contrary, demerit points can be taken up such as:
As the biggest merit, the freedom of wiring・layout goes up.
Usually, wiring should be protected to pass on the floor with mold, or it should be considered not to interfere office staffs walking. However, by wiring under the floor and putting out the line by the desk, it decreases the possibility of stumbling, and visual neat feeling changes very much.
No possibility of stepping on the wiring or hurting it with furniture also means to protect it.
From the beginning, the reason of it made for server room and clean room is exactly for this.
If it is a light weight type, as it is also easy to remove it, it can flexibly cope with layout change too.
In addition, for just in case, non-combustible material is often used for it.
The demerit point which is the most often taken up is, in the case of installing OA floor which was executed other floor work before, the floor goes up, there may be oppressive feeling. Therefore, we usually have to install a slope.
We install OA floor on the original floor, and in proportion to the heightened, usually in order to move out big household goods and stocked goods, equipment easily, we install a slope.
For this, in the case of having installed high OA floor particularly, the slope also becomes long, and extra space is going to be necessary.
In the modern times, as most of offices are constructed in anticipation of executing OA floor as the standard, so this problem only occurs when executing work from afterwards, not in order.
On lacking of strength which we took up above demerits, as there are various kinds of OA floor too. For example, there are「pillar supporting type」which is by using jack, freely pulling up to a certain degree, which can be freely wiring below, and「placing and spreading type」which is oppositely in block state and groove is on up and down.
As to the materials, there are various kinds too. There are inexpensive resin made, strong steel made, and heavy concrete made, and so on, which are manufactured by various makers and are being sold.
At heavy places such as server room and so on, we must adopt an OA floor to be able to endure heavy load.
Recently, resin made type with enough heavy durability products have been increasing too.
If you request the relative construction, it may be good to take counsel of requiring how heavy load bearing is needed to endure the OA floor.
1.We move goods at which area OA floor will be placed, we expose the floor ground.
2.After cleaning, we make the floor neat not to have凹凸. We get rid of protrusion and the like.
3.Placing cushion sheet, we go on lining up OA floor on it. We go on cutting the connecting parts such as edge part at the site.
4.We install slope・frame.(If it is a property of originally made for OA floor use, this process is not necessary. )
5.We go on spreading in finishing materials such as tile carpet, vinyl chloride tile and so on, on OA floor.
6.Others, after inspection, we pass the property to the tenant renter.
A special adhesive which can be sticked and stripped easily is used for tile carpet for OA floor finishing.
In the server room, antistatic function added tile such as SEIDEN tile C or the like is used.
We are brieflyintroducing tenant examples which our company executed construction before as follows.
The picture of curved surface wall construction. Seeing the lower part, concrete type OA floor is visible.
In this picture, tile carpet is partly constructed at the same place.
At the same site, different place. As it is concrete type OA floor, it is not possible to change the layout easily. However, there is satisfactory durability for wiring protection.
We so far explained What is OA floor? What kind of merits・demerits there are, and how it is constructed?
Nowadays, in the general office, the case of wiring been stretched on the floor has become little. However, because of office relocation or so, at the new location, if it is not OA floor, it is necessary to request the relative new construction to a contractor.
Including OA floor, we are happy to receive your full set order of interior decorative work.
