Ultrotherm Internal Insulation Boards

Protecting Against Condensation and Mould Growth

Mould growth caused by condensation is a major problem in the UK. The primary methods of preventing it are increasing the surface temperatures of walls and improving ventilation.

Installation of the Ultrotherm System increases the surface temperature of walls by insulating them – therefore reducing the risk of condensation. In most cases the installation of the Ultrotherm System will be enough to prevent condensation and mould growth. However it can also be used in conjunction with Dryzone System Mould Resistant Paint and ventilation measures such as Humidistat Fans.
