ProPERLA Masonry Crème creates an invisible insulation barrier for single skin buildings and those built with a cavity. It has been proven to help retain heat in walls and reduce heat loss.
UKAS accredited tests have demonstrated that by reducing water absorption of the walls, ProPERLA Masonry Crème lead to thermal performance benefits. It has been proven to meet ETAG 004;2011.
Testing in a hygrothermal chamber revealed that a wall coated in ProPERLA Masonry Crème and subjected to repeated heat-rain conditions in accordance with ETAG 034:2012, resulted in reduced heat loss when compared with the uncoated (control) wall. The uncoated wall showed on average an increase of 6⁰C of heat loss in comparison to the walls coated with ProPERLA Masonry Crème.
ProPERLA Masonry Crème 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 out twice as quickly as it would if the walls remained dry.
Independent testing has shown that ProPERLA Masonry Crème reduces water absorption by 96.3% and meets the British standard for water vapour resistance BS EN ISO 7783:2011.
