A high performance PIR insulation board suitable for partial fill cavity wall applications.
- External walls - partial fill masonry cavity.
Consult manufacturer for installation details.
Celotex CW4000 is a high performance, easy to install polyisocyanurate (PIR) insulation board featuring a low emissivity foil facing. Available in thicknesses from 40-100 mm, it is suitable for use in partial fill cavity wall applications.
Product features and benefits:
- Lightweight 1200 x 450 mm boards.
- Squared edges.
- Low emissivity foil facing.
- Achieves a BRE Green Guide A rating.
- BBA approved – certificate 16/5343.
- Excellent thermal conductivity - decreasing the thickness of insulation required to hit the required U-value, optimizing space in the construction design and helping to reduce the heating and cooling costs within the building.
- Low emissivity foil facing provides improved thermal performance in cavity air spaces, helping to reduce the U-value further.
- Easy to install – lightweight boards are straightforward to handle, fit and transport. Boards are 1200 x 450 mm to fit between standard wall tie spacing.
- BBA certification - third-party verification that the product has been assessed for its defined applications and is compliant with the relevant Building Regulations.
Application:
- External walls - partial fill masonry cavity.
Consult manufacturer for installation details.
