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 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.
A unique feature of Proctor Air’s BBA certificate is the clarification that it can be used on roofs featuring solar PV. Please speak to the technical department for further clarification.#

Novia VC200 Reflective is the latest addition to the Novia vapour control membrane range. Using enhanced technology, Novia has created a highly reflective vapour control layer suitable for use in insulated wall, roof and floor applications. VC200 Reflective helps to prevent interstitial condensation problems, and is also highly reflective and so delivers greatly improved R and u-values when correctly installed.

Vapour Control Layers (VCLs) are used to manage the transition through the building envelope of naturally occurring moisture vapour, which is produced by general building use. This product also performs the additional function of an air-leakage barrier, to prevent losses due to unwanted convection flows. We advise the use of Novia compatible butyl and foil sealing tapes to ensure a complete barrier integrity throughout the entire life of the product.
