With the revision of the Building Standards Act in 2025 approaching, there has been an increasing focus on insulation performance in recent times. Rockcell board has numerous achievements in applications such as "folded insulation" and "insulation reinforcement." - Flexibility that conforms to uneven surfaces, despite being a rigid board - Easy processability, allowing for simple cutting with a utility knife - Thickness options available from a minimal 5mm (which is less common among other insulation materials) up to 50mm, selectable in 5mm increments - Thermal conductivity of 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 work for contractors. To date, Rockcell board has been widely used as an insulation material under harsh conditions that require water resistance and weather resistance, such as in external insulation methods. Its independent bubble structure prevents water from passing through the insulation material itself, providing about 5 to 7 times the moisture resistance (vapor permeability resistance) compared to 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 compliant apartment buildings - Apartment building insulation renovations - Inns and hotels - Government offices - Nursing and elderly care facilities, etc.

The soundproof rubber mat "Otonashikun" is made from rubber scraps generated by manufacturers of automotive rubber parts. The raw material used is unused rubber scraps, which are of high quality while keeping costs down, making it a cost-effective option. Recently, there has been an increase in the conversion of Japanese-style rooms to Western-style rooms in the renovation of apartment buildings and public housing. Some have been troubled by the drum phenomenon caused by double flooring adopted for noise reduction to the lower floors... By simply installing double flooring over "Otonashikun," a reduction in the drum phenomenon can be expected. Of course, "Otonashikun" can also be installed directly on the floor. (Thickness can be accommodated in 5mm increments.) With "Otonashikun," flexible soundproofing measures can be tailored to fit your budget. Currently, we are offering samples through catalog downloads. Please contact us if you are interested. *The drum phenomenon of double flooring refers to a situation where air is trapped between the slab (floor concrete) and the panel floor, which amplifies sound due to the sealed air, causing impact noise to resonate like a drum.

"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 during construction require fire-resistant properties. Additionally, since these areas are often damp, moisture resistance, water resistance, and weather resistance are also necessary. 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 from the construction phase to after completion.

The soundproof rubber mat "Otonashikun" is made from rubber scraps generated by manufacturers of automotive rubber parts. The raw material used is unused rubber scraps, which are of high quality while keeping costs low, making it a cost-effective option. In offices with OA flooring, conversations from adjacent rooms can leak through the space of the underfloor air conditioning. This is especially important for soundproofing under the floor when multiple companies occupy the same floor, from the perspective of information management. By installing the soundproof rubber mat "Otonashikun" over the OA floor, it is possible to implement soundproofing measures easily and affordably. We are currently sending samples of the rubber mat to customers who inquire. If you are interested, please contact us.

Rockcell board is an insulation material that has been widely used under harsh conditions where water resistance and weather resistance are required, such as in external insulation 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 (vapor permeability resistance) of plastic-based foam insulation materials. Additionally, it can be applied using both injection and post-adhesion methods, making it an easy-to-install insulation material. 【Construction Examples】 - Single-family homes - Inns and hotels - Nursing and elderly care facilities, etc.

The underside of 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 that causes a fire, fire-resistant 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, meaning that if the ignition source is removed, it will only carbonize and will not spread flames. It is available in thin thicknesses of 5mm and 10mm, making it suitable for installation even in the limited space beneath an OA floor. It can be cut with a utility knife, and adhesive can be used, 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 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. Recently, there have been numerous reports of fire accidents at construction sites caused by sparks from welding igniting insulation materials. Insulation materials in areas exposed to sparks during welding or cutting of rebar and steel frames, such as under-slab and seismic isolation layers, require fire-resistant insulation. Additionally, since these areas are often exposed to high moisture and humidity, moisture resistance, water resistance, and weather resistance are also necessary. 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 under-slab and seismic isolation layers from the construction phase to after completion.
