Natural stone sheet (Flexible Stone Veneer)

Natural stone sheet (Flexible stone veneer) is an innovative finishing material made of thinly peeled sheets of natural rock. Although made of real natural stone, it is thin, lightweight, easy to cut with scissors, and bendable, making it possible to install even on curved surfaces such as cylindrical columns.

Using natural stone sheets as a finishing material, you can easily create a luxurious hotel-like space just by applying them. Because real natural stone is used, each sheet is a one-of-a-kind product, and the variety of natural stone designs created by nature over the years is soothing.

Natural stone sheets are a popular finishing material sold around the world, but their disadvantage is that they are backed with resin and fiberglass, which makes them flammable. For this reason, it is impossible to obtain certification as a noncombustible material.

However, at Each DreaM, we have succeeded in developing the world’s first natural stone sheet that does not burn. We are the only company in the world that offers completely non-combustible natural stone sheets, and as of August 3, 2022, we have passed preliminary testing approved by the Minister of Land, Infrastructure, Transport and Tourism.

History of Natural Stone Sheets (Flexible Stone Veneer)

It began when a German furniture designer accidentally discovered that when trying to remove natural stone tiles from a broken table top, the surface layer of the natural stone peeled off and remained attached to the resin, and after research and development, was granted a patent. Today, it is produced and sold worldwide.

 

Applications of natural stone sheets (DIY wall decoration, furniture remake, etc.)

Natural stone sheets can be used as a finishing material for walls, columns, ceilings, curved wall surfaces, furniture, lightweight signs, lighting, cabinets, doors, and many other areas. It is also suitable for DIY remodeling of stores and houses, and furniture remodeling.

 

Non-combustible natural stone sheet (natural stone non-combustible wallpaper)

World’s first! Completely non-combustible natural stone sheets. [ Non-combustible wallpaper ]

Each DreaM has developed the world’s first incombustible natural stone sheet.
We are the only company in the world that has a natural stone sheet that does not burn.
This sheet is made of real natural stone that can be used as incombustible wallpaper.

Natural stone sheets made by Each DreaM are backed by our special technology and our own fiber reinforced ceramic (FRC) and basalt fibers, and will not burn because all the constituent materials are made of incombustible materials.

Like natural stone sheets sold around the world, it is thin, lightweight, flexible, bendable, and can be easily cut with scissors. In addition to the features of conventional natural stone sheets, Each DreaM’s natural stone sheets have the added feature of being non-combustible.
Please check the video. You can see the thinness of about 1mm, flexibility, and non-inflammability.

Construction method (How to paste)

The installation method is the same as for commercially available natural stone sheets, which can be easily applied with architectural adhesives or double-sided tape. However, since the adhesives and double-sided tape will burn in case of fire, it is best to adhere them with noncombustible materials such as pin-tacker or inorganic adhesives. If you wish to use construction adhesives, we recommend natural stone board, which is natural stone sheet pressed onto calcium silicate board with our noncombustible material. With natural stone board, heat is controlled by the natural stone sheet and the calcium silicate board, so the heat does not go to the adhesive on the back side, and the adhesive will not burn.

 

Passed ISO 5660 heat generation test, a preliminary test approved by the Minister of Land, Infrastructure, Transport and Tourism

Passed ISO-5660 test for exothermicity of natural stone sheet.
Each DreaM natural stone board. passes ISO-5660 heat generation test.

EDM’s natural stone sheets have passed the “ISO-5660″ heat generation test, a preliminary test for MLIT certification, which was conducted on August 2, 2022. Therefore, we are in the process of obtaining MLIT certification if we apply for it.

Natural stone sheet itself is about 1 mm thin and flexible, so in order to give it strength, natural stone sheet and calcium silicate board are bonded with noncombustible material to make natural stone board, which has passed the test.

The total heating value is 0.2MJ/m2, which is much lower than the specified value of 8MJ/m2. The maximum heating rate is only 1.45 kW/m2, which is almost zero when viewed graphically. The material does not burn at all, and there is no change in shape, so you can confirm the overwhelming results.

【Details of exothermicity test】
In the ISO-5660 exothermicity test, the product is ignited and burned in an air environment with an external ignition source (ignition spark) and radiant heat (in the range of 10 ~ 100kW/㎡) applied, and the oxygen concentration in the combustion exhaust gas and exhaust gas flow rate are measured to determine the exothermic rate using the oxygen consumption method.

【Evaluation Points for Heat Generation Tests】
1. the total calorific value for 20 minutes after the start of heating shall be 8MJ/㎡ or less.
2. No cracks or holes penetrating to the back surface that are detrimental to fire protection shall be present for 20 minutes after the start of heating.
3. the heating rate shall not exceed 200kW/㎡ for more than 10 seconds continuously for 20 minutes after the start of heating.

Test Number: ⅢC-21-0036
Test name: Exothermicity test (Cone Calorimeter Test)
Test Date: August 2, 2020
Test specimen: Natural stone board (natural stone sheet + fiber-reinforced ceramic solution + calcium silicate board)

The major difference between commercially available natural stone sheets and those made by EDM is their noncombustibility.
Natural stone sheets sold around the world reinforce the strength of natural stone with resin and fiberglass. Therefore, in the event of a fire, even if the natural stone does not burn, the resin of the reinforcement material will burn, as will the adhesive and double-sided tape that adheres it to the wall. Toxic gases are also produced in case of fire.

Natural stone sheets made of EDM are backed with Basalt Fiber Reinforced Ceramic (FRC), our special technology, and the entire structure is made of noncombustible material, so it will not burn and will not emit toxic gases.
The product has passed the ISO-5660 nonflammability test.

 

Frequently Asked Questions (Q&A)

Is the thickness of the natural stone sheet constant?

Since natural stones are thinly peeled by hand along the cleaved surface to form sheets, the thickness is not consistent.
The uneven appearance of the peeled natural stone is very unique and is the beauty and charm of natural stone sheets.

Are there any natural stone sheets other than the color variations shown in the catalog?

Since natural stone sheets are made of real natural stone, no two are exactly alike, and there is variation in color.
There are many natural stone sheets available in colors other than those shown in the catalog, so please contact us for more information.

Is the installation method (how to apply) the same as for general natural stone sheets?

Natural stone sheets are generally installed by bonding them to the wall with adhesives or double-sided tape. However, if glued with adhesives or double-sided tapes, they will burn in case of fire, so we recommend that they be discreetly pin-tacker or glued with a nonflammable adhesive.
Alternatively, with our natural stone board, even in the event of fire, the natural stone sheet and calcium silicate board provide heat protection, so there is no problem in bonding with general construction adhesives because the heat will not reach the back of the calcium silicate board, which is the reinforcement material.

What is the heat resistance temperature of natural stone sheets?

The natural stone itself used in the natural stone sheet has a heat resistance temperature of 1000℃.
The reinforcement part of the natural stone sheet is made of Fiber Reinforced Ceramics (FRC) developed by our company, which does not burn even at a temperature of 1200℃.
