Stay Dry & Warm
When applied ProPERLA exterior wall coatings create a waterproof, super hydrophobic surface. Independent tests have shown that it reduces water absorption by 93.4% and therefore meets the British standard for water vapour resistance BS EN ISO 7783:2011.
Test demonstrated that by reducing water absorption of the walls, the wall coating leads to thermal performance benefits & has been proven to meet EAD 040083-00-0404. With Utility bills at an all-time high ProPERLA wall coatings have never been so beneficial.
Improves thermal efficiency and contributes to lower energy consumption and lower energy bills, by keeping walls dry. Damp walls act as ‘thermal bridges’ – enabling heat to transfer from the inside to the outside environment 50% quicker as it would if the walls remained dry.
Crucially, ProPERLA Facade Coating is a highly breathable wall coating. Water vapour permeability testing was conducted in accordance with BS EN ISO 7783:2011 and it demonstrated that the coating had little effect on the water vapour diffusion of the substrate.
