The next evolution of roofing underlay technology; Proctor Air has been developed and manufactured to our precise specifications and requirements. This ensures the on-site performance of our material mirrors the off-site performance, while a 15 year warranty ensures peace of mind for any project, now and in the future.
Hydrophobic additive in all three layers of this next generation product amplifies water holdout, and this, alongside an air permeability of 35 m3/m2.hr.50Pa and an Sd-value of 0.02m means Proctor Air delivers robust and dependable performance.
Proctor Air has a Hydrostatic Head of water of over 1m as recommended by NFRC Technical Bulletin 6. It is good practice not to leave the underlay exposed longer than necessary. Under BS 5534, Proctor Air can be used in Wind Zones 1-4 at maximum 345mm battens centres without additional tape. At the same time, it reduces the risk of issues occurring in roof spaces due to poorly installed VCLs or ventilation, since neither is needed.
This means Proctor Air can be specified on all roof types not just without low- and high-level ventilation, or a vapour control layer, but with confidence.
After 25 market-leading years, The A. Proctor Group are once again pushing roofing forward and embracing the future of membrane technology.
The “Air” to the throne has arrived.
