Proctorwrap Reflect® is a vapour-permeable, low-emissivity membrane specifically designed to enhance the thermal performance of timber and steel frame structures.

This non-woven polypropylene foil laminate provides excellent breathability, as well as secondary protection to the building during construction. It 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 vapour resistance requirements set out by TRADA and the NHBC. The existing legislation requires a breather membrane 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.

The A. Proctor Group can provide a range of solutions, with U-values, down to as low as 0.18W/m2 K in standard timber frame walling applications.

Once Proctorwrap Reflect is applied to the walls, the primary wall covering should be installed within 3 months.

Proctorwrap Reflect must be covered as soon as practically possible on completion of installation. Any damaged areas should be repaired or replaced before completion.
