Key Features
- Edge Profile: Tongue and groove edge profile for a continuous layer of insulation and optimal thermal performance, as well as protection from wind-driven rain.
- Foil Facing: Features a low emissivity foil facing on both sides, enhancing thermal performance in sealed cavity air spaces and improving the achievable U-value.
- Ease of Installation: Lightweight and easy to cut and handle, resulting in an easy installation process. The boards are sized to fit standard cavity wall tie spacing.
- BBA Certification: BBA approved – certificate 16/5343 for Full Fill Cavity Walls.
Applications
- Use: Ideal for full-fill cavity wall applications. The product can be installed with up to a 10mm residual cavity (to support ease of installation and accommodate mortar squeeze) or as a full-fill solution with no residual cavity.
Storage and Handling
- Storage: Should be stored indoors in a dry space on a flat surface. If indoor storage is not an option, weatherproofing materials should be applied to protect the boards from weather conditions.
Celotex TC1090 Thermaclass Cavity Wall 21 is a high-performance PIR insulation board designed for cavity wall applications, offering excellent thermal performance with reduced thickness to meet target U-values. Its engineered tongue and groove joint and foil facings make it a robust and effective solution for cavity wall insulation.
