ZEH-compatible 'Rock Cell Board' for use in thermal insulation and insulation reinforcement.
Inorganic thermal insulation material Rockcell board
The lock cell board made of rigid material with flexibility follows the irregularities of the structure and simplifies the contractor's work.
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.

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 affordable, high-quality, and highly durable. Other products are also manufactured using our original technology.
