What is Proctorwrap Reflect?

Proctorwrap Reflect is a vapour–permeable, low–emissivity wall membrane designed to enhance the thermal performance of timber and steel frame structures while providing reliable secondary protection during construction

Where is Proctorwrap Reflect typically used?

It is used over sheathing on the external face of timber and steel frame walls to provide vapour permeability, water resistance, and improved thermal performance in the adjacent cavity.

How does Proctorwrap Reflect support moisture management?

Proctorwrap Reflect has vapour permeability with a vapour resistance Sd value of 0.08 m, allowing water vapour to pass through the membrane while maintaining a class W2 resistance against the passage of liquid water.

Does Proctorwrap Reflect help improve thermal performance?

Yes. It utilises a low–emissivity foil which gives it a reflective surface. This enhances the thermal resistance of an adjacent cavity in wall buildups, improving the U–values in timber and steel frame constructions.

What are the key benefits of Proctorwrap Reflect?

• Vapour–permeable and reflective membrane for improved thermal performance, achieving a thermal resistance of 0.71m²K/W
• Provides secondary protection to the building structure during construction.
• Low vapour resistance – compliant with NHBC requirements for use a vapour permeable membrane.
• Certified by BM TRADA.
• Water resistant and suitable for typical site conditions.
• Multiple roll widths available (1.5 m, 2.7 m, and 3 m).
• Has an EPD to demonstrate low environmental impact.

What are the available roll sizes of Proctorwrap Reflect?

Proctorwrap Reflect is available in a range of wide rolls including 1.5 m × 50 m, 2.7 m × 100 m, and 3 m × 100 m options.

Is Proctorwrap Reflect certified or independently verified?

Yes. Proctorwrap Reflect has received Q–Mark certification from BM TRADA (certificate number CPS-053), providing independent verification of performance and manufacturing quality.

Does Proctorwrap Reflect offer protection during construction?

Yes – the membrane acts as a secondary weather protection layer, safeguarding the structure from rain and wind during construction before the primary external cladding is installed.

Can Proctorwrap Reflect contribute to building regulation compliance?

Yes. Its vapour resistance and thermal performance characteristics support compliance with regulatory standards.

Is technical support available?

Yes. Technical guidance, specification advice, and detail support are available to help ensure optimal performance and integration with your wall buildups. We can also conduct u-value calculations to demonstrate the effect of using Proctorwrap Reflect in your wall construction and calculate the risk of interstitial condensation.
