Hard to treat cavities are defined as:
The most cost effective and least disruptive way to treat cavities of this kind is to inject insulation material directly into the existing cavity.
WALLTITE® CV 100 is the injection grade. Applied in liquid form, the WALLTITE® CV 100 takes fractionally longer to expand into its finished closed cell foam, ensuring that all irregularities within the cavity are covered, sealed and insulated.
Injected into the hard to treat cavity, WALLTITE® offers the following advantages to specifier and homeowner:
The results that can be achieved will vary depending on the material used, but calculations based on the use of WALLTITE® CV 100 rigid closed cell foam insulation injected into a 40mm cavity suggest that the U-value of the refurbished wall should be in the region of 0.46W/m2K to 0.56W/m2K depending on the make up of the internal and external walls.
