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.

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 allows for 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 renovations of apartment buildings and public housing. When double flooring is adopted to mitigate noise to the lower floor, it can sometimes lead to the "drum phenomenon." However, simply installing double flooring on top of "Otonashikun" can help reduce this phenomenon. Of course, "Otonashikun" can also be installed directly on the floor (with a thickness available in 5mm increments). With "Otonashikun," flexible soundproofing measures can be implemented according to your budget. Currently, we are offering samples through catalog downloads. If you are interested, please contact us. *The drum phenomenon of double flooring refers to a situation where air is trapped between the slab (floor concrete) and the panel floor, amplifying sound due to the sealed air, causing impact noise to resonate like a drum.

• Anti-vibration rubber

"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.

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 causing a fire, fire-resistant insulation materials are 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 fire 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 under OA floors. It can be cut with a utility knife and can be easily installed using adhesive. 【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 easily installed with adhesive ■ 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 from inorganic calcium carbonate, making it fire-resistant ■ Can be bent and installed without slitting, even on curved surfaces *For more details, please feel free to contact us.

The "TB Board Method" by Fujikasei Kogyo is an external insulation method for wooden house foundations that has excellent termite resistance. The external insulation method offers several advantages, including increased durability of the foundation, improved thermal environment under the floor, and labor-saving construction. Additionally, by incorporating termite resistance, it effectively addresses the weaknesses of traditional external insulation methods against termite damage. In the unlikely event that termites cause damage to the building, a 10-year termite insurance policy is provided for peace of mind. 【Features】 ■ Safe termite resistance ■ Non-combustibility ■ Insulation properties ■ Moisture and water resistance ■ Lightweight and easy to process *For more details, please refer to the catalog or feel free to contact us.
