Reflective Breather Membrane for Timber and Steel Frame Construction
Proctorwrap Reflect is a water resistant, non-woven polypropylene, foil faced laminate with a patented three layer composition, providing breathability, as well as secondary protection to the building during construction. Proctorwrap Reflect is vapour permeable, has low emissivity and an enhanced foil surface designed to improve the thermal resistance of timber and steel frame structures. It has a high strength to weight ratio.
The product is installed on the external face of the timber frame, foil side face out, similar to that of a traditional breather membrane but with added thermal benefits.
Proctorwrap Reflect complies with the low vapour resistance requirements set out by TRADA and the NHBC. The existing legislation requires a breather membrane in walls to have a vapour resistance not greater than Sd 0.12m / 0.6 MNs/g. Proctorwrap Reflect has a vapour resistance of Sd 0.08m / 0.4 MNs/g.
We can provide a range of solutions, with U-values down to as low as 0.18W/m2 K in standard timber frame walling applications.
