Tests have shown that a damp content of 5% in a plain brick wall, for example, can lower the insulation performance by up to 50%, especially where cavity wall insulation has been installed. Porous building materials, such as natural stone and brick normally have good insulating properties as they have air filled cavities, which offer low thermal conductivity, but only when they are dry.

By having defected cavity wall insulation removed it will prevent thermal bridging to the interior of your property but will also leave your exterior walls with 0% insulation.

By applying Properla superhydrophobic masonry creme to the exterior walls you will increase thermal resistance, reduce frost damage and prevent the growth of microbial spores.

Properla will reduce heat loss by 30% and comes with a 20 year manufactures performance guaranty.

Super Hydrophobic Wall Barrier key features:

Super Hydrophobic

Water cannot stick to the coated surface but forms droplets that run off the surface.

Insulation Barrier

Reduces water absorption by more than 95%. Dry walls mean less heat loss.


Masonry remains clean and attractive as dirt is unable to take hold.


Water and moisture are able to escape the masonry due to the high breathability rating of the products.
