PROCTOR Air® Breathable Roof Membrane - 1m x 50m

Proctor Air® is an air and vapour-permeable, highly water-resistant roofing underlay. Its characteristics allow even very complex pitched roofs to breathe, without the need for air gaps or secondary venting.

The high-performance meltblown core at the heart of Proctor Air allows natural air movement to ‘supercharge’ the passage of moisture vapour from the roofspace, making the formation of condensation in the roofspace virtually impossible.

PROCTOR Spacetherm® Silica Aerogel Blanket

Aerogel is a synthetic porous ultralight gel-like material created by removing the liquid component from gel and replacing it with gas, without any degradation to the gel structure. This produces an extremely low thermal conductivity which is perfect for thermal insulation.
