Glidevale Protect provides new solution for solar roofs

  • 23 Aug 2023

With the recent update of the Building Regulations Part L and the use of solar photovoltaic panel (PV) systems on the rise, there is an ongoing need to reduce carbon emissions within new and existing homes. To meet demand, UK building materials producer Glidevale Protect launches a comprehensive collection of membrane and ventilation products for use on all cold and warm pitched roofs where in-roof solar PV panels feature.

One new addition to the range is Protect A1 Solar, a heavy duty, type HR impermeable roofing underlay. The 145gsm membrane offers unrestricted use in wind uplift zones 1-5 at the maximum batten gauge of 345mm to BS 5534, suitable for use throughout the UK & Ireland. Together with Glidevale Protect’s extensive choice of high and low level ventilation options, Protect A1 Solar offers one of a number of trusted solutions to reduce risk of condensation forming on the underside of in-roof solar PV panels.

Ventilation strategy

This can ensure the correct ventilation strategy is in place, avoiding risk of rotting roof timbers. Due to its impermeable design and high resistance to water vapour transfer, Protect A1 Solar eliminates the need for a ventilated counter batten space above the membrane, saving labour time and material cost.

Other Glidevale Protect pitched roofing membranes such as vapour permeable type LR underlays are usable in conjunction with in-roof solar PV panels. The Glidevale Protect Technical team offers complete guidance to aid specification via a full roof ventilation strategy and house type take off.

Matt Neary, Product Manager at Glidevale Protect, says: “We are pleased to offer a complete range of membrane options which, when used in conjunction with our ventilation products, gives our customers a tried and tested product package where in-roof solar PV panels are used.”
