"Rock Cell Board" is an insulation material that excels in workability, processability, adhesion, and durability, primarily used for external and internal insulation. Since its main raw material is inorganic calcium carbonate, it only carbonizes and does not burn. It can be cut with a utility knife, can use adhesives, and is easy to install. It allows for low-cost installation without special parts or extra processes, including "external insulation tile finishing," and there are examples of installation such as "internal insulation renovation," where mortar is applied directly to the product and wallpaper is pasted to complete the work. 【Installation Examples】 ■ External insulation tile finishing (insertion) ■ External insulation tile finishing (post-application) ■ External insulation renovation with mortar finishing ■ Internal insulation renovation *For more details, please refer to the PDF materials or feel free to contact us.

The floor beneath a free access floor is prone to surface condensation if it is not insulated. Additionally, due to limited space, it may not be possible to install thick insulation materials. In the event of a short circuit and fire, non-combustible insulation materials will be necessary. Lock cell board is a fire-resistant insulation material made primarily from inorganic calcium carbonate. It has self-extinguishing properties, and once the source of fire is removed, it only carbonizes without spreading flames. It is available in thin thicknesses of 5mm and 10mm, making it suitable for installation even in the limited space beneath a free access floor. It can be cut with a cutter and can also use adhesive, making installation easy. 【Features】 ■ Minimal aging changes, contributing to the longevity of the building ■ Low-density foam with a completely independent bubble structure ■ Can be cut with a utility knife, and adhesive can be used for easy installation ■ Various finishes are possible, including tile, paint, and mortar ■ High water resistance and moisture resistance, resulting in minimal reduction in insulation performance and reduced internal condensation ■ Fire-resistant due to the use of inorganic calcium carbonate as the main raw material ■ Can be bent for installation on curved surfaces without slitting *For more details, please feel free to contact us.

What is concerning due to the earthquake is the detachment of exterior materials. There have been reports of injuries to passersby caused by the detachment of exterior materials. Rockcell board has flexibility and adaptability, which allows it to absorb the movements of the substrate caused by seismic shaking, making it difficult for the surface finishing materials to transmit movement. Additionally, since Rockcell board is primarily made of inorganic calcium carbonate, it has good compatibility with other inorganic materials such as mortar and concrete, allowing for direct tile application. 【Features】 - Minimal aging changes, contributing to the longevity of buildings - Low-density foam with a completely independent bubble structure - Can be cut with a utility knife and is easy to install with adhesive - Various finishes are possible, including tile, paint, and mortar - High water resistance and moisture resistance, resulting in minimal reduction in thermal insulation and reduced internal condensation - Inorganic calcium carbonate as the main raw material makes it fire-resistant - Can be bent and installed on curved surfaces without slitting *For more details, please feel free to contact us.

"Rock Cell Board" is an insulation material that excels in workability, processability, adhesion, and durability, primarily used for external and internal insulation. Since its main raw material is inorganic calcium carbonate, it only carbonizes and does not burn. It can be cut with a utility knife, can use adhesives, and is easy to install. It has very good adhesion with various adhesives, mortars, and cements, allowing for direct tile application.

Rockcell board is a fire-resistant insulation material made primarily from inorganic calcium carbonate. It has self-extinguishing properties, and when the fire source is removed, it only carbonizes without spreading flames. Even if welding sparks hit it at a construction site, it will only carbonize without catching fire. 【Features】 - Minimal aging changes in the insulation material, contributing to the longevity of the building. - Low-density foam with a completely independent bubble structure. - Can be cut with a utility knife, making processing easy. - Various finishes are possible, including tile, paint, and mortar. - High water resistance and moisture resistance, resulting in minimal reduction in insulation performance and reduced internal condensation. - Made primarily from inorganic calcium carbonate, making it fire-resistant. - Can be bent and installed on curved surfaces without slit processing. *For more details, please feel free to contact us.

"Rock Cell Board" is an insulation material that excels in workability, processability, adhesion, and durability, primarily used for external and internal insulation. Recently, there have been numerous reports of fire accidents at construction sites caused by sparks from welding igniting insulation materials. Insulation materials exposed to sparks during welding or cutting of rebar and steel frames need to be fire-resistant. Additionally, since these areas are often damp, moisture resistance, water resistance, and weather resistance are also required. Rock Cell Board, which is fire-resistant and has high moisture and water resistance, is an insulation material that can be safely and securely used for insulation in underground pits, both during and after construction.

Rockcell board is an insulation material that has been widely used under harsh conditions requiring water resistance and weather resistance, such as in external insulation construction methods, and it can be directly finished with tiles. Due to its independent bubble structure, the insulation material itself does not allow water to pass through and has about 5 to 7 times the moisture resistance (water vapor permeability resistance) of plastic foam insulation materials. Additionally, it can be installed using both the injection method and the post-adhesion method, making it an easy-to-install insulation material. 【Installation Examples】 - Single-family homes - Inns and hotels - Nursing and rehabilitation facilities, etc.

With the revision of the Building Standards Act in 2025 approaching, there has been an increasing focus on insulation performance in recent times. Rockcell boards have numerous achievements in applications such as "folded insulation" and "insulation reinforcement." - Despite being a rigid board, it has the flexibility to conform to uneven surfaces. - It can be easily cut with a utility knife, making it easy to process. - Thickness options start from a low 5mm, which is less common in other insulation materials, with product specifications available from 5mm to 50mm in 5mm increments. - The thermal conductivity is 0.037 W/(m·k) *Measurement method JIS A 1412. Due to these characteristics, it has been considered as an insulation material that simplifies the contractor's workload. To date, Rockcell boards have been widely used as insulation materials under harsh conditions that require water resistance and weather resistance, such as external insulation methods. Due to their closed-cell structure, the insulation material itself does not allow water to pass through, offering about 5 to 7 times the moisture resistance (vapor permeability resistance) of plastic-based foam insulation materials. Additionally, being primarily composed of inorganic materials, it has a proven track record of over 40 years as a fire-resistant insulation material. 【Construction Examples】 - ZEH-M/ZEH-M Oriented multi-family housing - Insulation renovation for multi-family housing - Inns and hotels - Government offices - Nursing and rehabilitation facilities, etc.
