Internal Wall Insulation

Condensation is one of the most common causes of damp in the indoor environment. Fortunately, there are numerous ways to help combat the problem, one of which is the installation of internal wall insulation.

Twistfix is a proud supplier of ISO-THERM, an innovative thermal wall insulation solution designed and developed by leading brand Wykamol. Combining waterproofness with vapour-permeability, the product enables walls to resist the lateral transference of damp while providing exceptional thermal benefit that results in dramatic cost-savings in terms of energy usage. ISO-THERM insulation is sold as part of a comprehensive kit which also contains the specialist adhesive required for installation.
