Key Features and Specifications of the 60mm Version
The Celotex CW4000 60mm board is engineered to deliver effective insulation performance through its precise specifications and physical attributes. It measures 1200 mm by 450 mm, with a thickness of 60 mm, and is manufactured from polyisocyanurate (PIR), a material recognized for its low thermal conductivity of just 0.022 W/m·K. The foam core has a density of approximately 30 kg/m³, ensuring the board is lightweight and easy to handle during installation. Polyisocyanurate (PIR) is a chemically inert material, contributing to its durability and resistance to moisture. Each individual board covers an area of 0.54 m², while a pack of ten provides a total coverage of 5.40 m², simplifying project planning. The squared edges of the boards facilitate accurate alignment and a seamless fit, supporting efficient installation. Its high compressive strength of 120 kPa guarantees durability and stability in various applications. The product is certified with BBA approval, confirming compliance with UK construction standards. Additionally, the surface's flame classification as Class 1 ensures it meets safety requirements for fire performance in building environments.
Thermal Performance and Environmental Impact
Exceptional thermal performance is a key attribute of the Celotex CW4000 60mm insulation board, primarily due to its low thermal conductivity value of 0.022 W/m·K. This effectively minimizes heat transfer through cavity walls, supporting energy efficiency within buildings. Such insulation efficiency plays a significant role in reducing heat loss, resulting in decreased heating and cooling demands. The foil facing enhances this performance by reducing radiative heat transfer within sealed air spaces. Additionally, the adjustable thickness of the board allows for meeting specific U-value targets without increasing overall material usage, offering flexibility in installation. From an environmental perspective, the product benefits from its polyisocyanurate composition, which helps maximize energy savings over the lifespan of the building. Its BRE Green Guide rating of A further demonstrates its environmentally friendly credentials. Polyisocyanurate is known for its excellent thermal insulation properties, contributing to its high performance. Certification affirms its compliance with performance standards, ensuring that both thermal effectiveness and sustainability are consistently maintained.
Installation Process and Compliance Standards
Proper installation of Celotex CW4000 60mm insulation boards begins with careful preparation of the wall surfaces to ensure optimal adhesion and effective thermal performance.
Surfaces must be clean, dry, and permeable, with any gloss paint, vinyl wallpaper, or loose materials removed to promote proper bonding. Damaged areas and dampness should be repaired before fitting insulation. Ensuring surface quality is crucial for maximum insulation effectiveness.
Accurate measurements of wall heights and cavity widths are essential, with precise markings for battens or installation points.
Boards are cut on stable surfaces using fine-tooth saws or utility knives and fitted snugly between studs to minimize gaps.
Seal perimeters with gypsum-based adhesives and tape, then secure boards with mechanical fixings such as battens and screws.
All installation steps must adhere strictly to the manufacturer's instructions and relevant standards, ensuring continuous vapour control and thermal integrity.
