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.
Water cannot stick to the coated surface but forms droplets that run off the surface.
Water and moisture are able to escape the masonry due to the high breathability rating of the products.
Masonry remains clean and attractive as dirt is unable to take hold.
Reduces water absorption by more than 93%. Dry walls mean less heat loss.
ProPERLA wall coatings have been rigorously tested and certified by the UKAS accredited testing laboratory, Lucideon (No. 0013), to give you peace of mind.
Lucideon is an independent materials testing and analysis laboratory. Using their state-of-the-art facilities and scientific expertise, Lucideon can thoroughly test product performance and provide impartial results.
ProPERLA wall coatings have been tested for durability, thermal insulating properties, breathability and water repellency.
