Sopratherm CW4050 (manufactured by Soprema and formerly known as the Celotex CW4000 product range) is a high-performance insulation board aimed specifically at partial fill cavity wall applications. While the brand name has updated from Celotex to Sopratherm, the product specifications and exceptional quality remain exactly the same.
Manufactured from rigid polyisocyanurate (PIR) using a blend of blowing agents that have zero ozone depletion potential (zero ODP) and low global warming potential (GWP). These handy-sized sheets also benefit from low emissivity foil facings on both sides.
With Sopratherm CW4050 (Celotex), you are specifying an insulation board that:
- Is easy to fit between wall ties using cavity tie clips for retention
- Comes in conveniently sized boards for installation between cavity wall ties
- Includes low emissivity foil facings giving improved thermal insulation performance within cavity air spaces
- Has excellent dimensional stability
- Provides reliable long-term energy savings for buildings
- Is available in a standard board size of 1200mm x 450mm
Multi-use Sopratherm / Celotex cavity insulation boards
Although Sopratherm CW4050 is designed specifically for use in partial-fill cavity wall applications, it can be used for any application where there is a need for a smaller-sized sheet of PIR insulation. For example, it is perfect for insulating loft spaces when access is restricted and the larger Sopratherm GA4000 sheets (formerly Celotex GA4000) won't fit through access hatches.
