Its closed-cell structure resists moisture, while foil facings on both surfaces reflect heat and enhance thermal efficiency. Certified by the BBA and rated highly by the BRE Green Guide, this board complies with UK building standards. Proper installation involves ensuring a smooth surface, correct fixation, and sealing, allowing for maximum performance; further detailed guidance is available to ensure successful application.
Material Composition and Technical Specifications
The Celotex CW4000 75mm insulation panel is primarily manufactured from a core of polyisocyanurate (PIR) rigid foam. This core provides excellent thermal insulation and enhances the panel’s structural integrity. This core material, with a density of approximately 30 kg/m³, offers a suitable combination of lightweight handling properties and durability, facilitating easy installation without compromising strength. The PIR foam features a closed-cell structure that effectively resists moisture ingress and maintains breathability. This is a crucial factor in preventing moisture accumulation within wall cavities. Both surfaces of the panel are finished with low emissivity foil facings, which further improve thermal performance by reducing radiant heat transfer. Moreover, the product is environmentally friendly, boasting zero ozone depletion potential and a low global warming potential, ensuring compliance with contemporary sustainability standards. The PIR foam is also classified as chemically inert, contributing to the product’s durability and safety in building environments.
Thermal Performance and Certification
The exceptional thermal performance of Celotex CW4000 75mm insulation panels is achieved through carefully engineered properties that enhance energy efficiency and ensure compliance with UK building standards. Featuring a thermal conductivity of 0.022 W/m.K, these panels effectively reduce U-values, enabling the use of thinner insulation layers whilst meeting regulatory requirements. The foil facing on the panels improves heat reflection and enhances U-values in sealed cavities. This contributes to more stable indoor temperatures and minimizes energy loss over time. The panels are designed with environmentally friendly materials, supporting sustainable construction practices. Accreditation from the British Board of Agrément (BBA) and a high A rating in the BRE Green Guide affirm that these panels meet both national and local standards for cavity wall insulation. It is important to note that ongoing compliance hinges on correct installation practices. Celotex CW4000 is suitable for applications where fire safety, durability, and environmental considerations—such as the use of low GWP gases—are priorities. Proper installation ensures the insulation performs optimally, supporting energy efficiency and safety in UK buildings.
Installation Guidelines and Practical Applications
Proper installation of Celotex CW4000 75mm insulation panels necessitates careful preparation to optimize performance and longevity. Begin by ensuring that the surface is smooth, removing any projections or uneven areas to allow the boards to sit evenly. The thermal performance of the insulation is maximized when the surface is prepared correctly. Surface preparation is crucial for a secure and effective installation. If necessary, apply a suitable smoothing compound or suitable fixings to create an even plane, supporting the insulation panels adequately. When installing the insulation, a damp-proof membrane should be fitted to prevent moisture ingress. This membrane must be aligned with the existing damp-proof course to maintain the integrity of the building’s moisture barrier. Wall ties should be positioned at centers of 600 mm horizontally, particularly for the first row, to provide adequate fixing and support. Installing appropriately spaced wall ties ensures a stable and secure insulation layer. Use a compatible adhesive or timber battens to establish a continuous perimeter seal around the insulation panels. This not only improves thermal performance but also helps prevent air leakage. Storage of the boards must be managed with care. Keep them protected from direct sunlight and moisture, storing them flat in a dry, covered location to prevent damage or warping before installation. Additional tips for a successful installation include fitting the boards tightly together to prevent gaps and maintaining a clean, dust-free surface during installation. Proper handling and storage will ensure the insulation maintains its quality and effectiveness over time.
Conclusion
The Celotex CW4000 75mm provides a high-performance insulation solution recognized for its reliable thermal properties, supported by relevant certification. Its composition ensures effective thermal resistance, making it suitable for a variety of building applications across the UK. Proper installation, in accordance with the manufacturer’s guidance, is essential to optimize both efficiency and safety.
For the best results, it is important to adhere to detailed technical specifications and comply with current UK building regulations. This helps to ensure energy efficiency and regulatory compliance throughout the lifespan of the insulation.
