ZEH-compatible 'Rock Cell Board' usable for thermal insulation and insulation reinforcement.
Inorganic thermal insulation material Rockcell board
The lock cell board with flexibility has the ability to conform to the irregularities of the structure, simplifying the work for the installer.
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.

Company information
Product development focused on "safety" and "environment." The external insulation material "Rock Cell Board" has excellent adhesion to mortar, allowing for both embedded and post-application use, and can be finished directly with mortar or tiles. This means that no special installation hardware or processes are required, enabling low-cost external insulation. Additionally, we can provide cut samples of the Rock Cell Board, so please feel free to contact us. The soundproof rubber mat "Otonashikun" is made from material recycled from automotive rubber parts, making it inexpensive, high-quality, and highly durable. Other products are also manufactured using our original technology.
