Prestoplan's PresWall Plus system will deliver an independently proven "Ψ" value performance that is "built in", often eliminating the need for renewable technologies.
Most reasonably well constructed systems are delivering performance in line with the current Accredited Construction Details (ACD y=0.08). The PresWall Plus system has been developed to deliver a cost effective, thermographically modelled performance of y=0.031¹. This provides valuable points to attain Code Level 3 or 4 compliance without requiring costly renewable technology.
