Energy Efficient Wall Coating

ProPERLA wall coating from Cosy Home Energy is a range of exterior waterproof paints & coatings designed to reduce energy costs and protect homes.

Moisture in building materials is a key driver to energy loss. Wet materials transfer heat much quicker than dry materials. Tests have shown that a damp content of 5% in a plain brick wall can lower the insulation performance by up to 50%. By keeping walls and roofs dry, ProPERLA waterproof paints & coatings help to improve thermal efficiency.



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.

Insulation Barrier

Reduces water absorption by more than 93%. Dry walls mean less heat loss.
