The Celotex Cavitywall is perfect for superior performance thermal insulation in application of partial fill cavity wall insulation. It includes a polyisocyanurate rigid foam and insulation core, along with a thermal conductivity that comes out to be 0.022 W/mK. There are also aluminium foil facings with low emissivity at both the sides. This is formed through a rigid polyisocyanurate (PIR) through a blend of blowing agents with low global warming potential (GWP) and zero ozone depletion potential (zero ODP).


Advantages

    1. Conveniently fits in between cavity wall ties through cavity ties clips
    2. Clips offer Retention
    3. Gives long lasting reliable energy savings for all buildings
    4. Foil facers with low emissivity provide improved thermal insulation along with cavity walls air spaces
