75mm Celotex Cavity Wall Insulation Board Product Specifications
Homeowners lose over a third of the heat in their homes through the walls. By investing in partial-fill 75mm Celotex cavity wall insulation, you can reduce your energy bills and keep your home warmer for longer. It is a closed-cell, water repellent insulation board meaning not only will the boards provide weather-tight protection but moisture won't compromise insulation performance.
It is made from PIR (rigid polyisocyanurate), which has a thermal conductivity value of 0.022 W/mK. PIR is a good choice for homeowners who want to protect their homes from the elements and prevent air movement and heat loss in vulnerable exposure zones. PIR insulation promises durability and excellent thermal protection, better than that of most other building materials.
Let's check the specs:
- Flanked by low emissivity foil facings on either side for improved thermal insulation performance in cavity air spaces
- Can be fitted in new build or refurbishment insulation projects
- Celotex CW4075 is British Board Approved (BBA) for use as partial fill insulation in cavity walls
