ZEH-compatible 'Rock Cell Board' usable for thermal insulation and insulation reinforcement.
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.
basic information
【Specifications】 ■Size: 910mm × 1820mm ■Thickness: 5mm to 50mm (in 5mm increments) *If exceeding 50mm, it will be bonded with two or more sheets. 【Seven Characteristics of Lock Cell Board】 ■Durability Minimal aging changes, contributing to the longevity of buildings. ■Insulation A low-density foam with a completely independent bubble structure. ■Combustibility Made primarily from inorganic calcium carbonate, it only carbonizes and does not burn. ■Workability Can be cut with a utility knife, can use adhesives, and is easy to install. ■Adhesion Excellent adhesion with all types of adhesives, mortars, and cements, allowing for use with driven applications without affecting construction time, enabling low-cost external insulation construction. ■Aesthetic Quality Can be finished with tiles, paint, mortar, and various other finishes, allowing for high aesthetic quality in construction at low cost. ■Other High water resistance and moisture resistance, resulting in minimal reduction in insulation properties and reduced likelihood of internal condensation.
