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.
