The use of solar PV is an area of growing importance as a way of meeting Building Regulations Part L requirements and ensuring energy efficiency measures are in place.
Choosing the right underlay and ventilation for a roof which has integrated in-roof solar panels is fundamental to ensure risks of condensation are minimised.
This can be challenging due to the abundance of information and varying recommendations from membrane suppliers in the market. Glidevale Protect aims to simplify this process.
While technically any type of membrane can be installed—whether it’s an air and vapour permeable membrane (LR) like Protect Viking Air, a vapour permeable (LR) membrane like Protect VP300 and VP400, or an impermeable underlay (HR) like Protect A1 Solar—the important factor is that the ventilation requirements can differ depending on whether it is a warm or cold roof as well as the underlay type that is ultimately chosen.
Glidevale Protect has answered some of the most commonly-asked questions to help make things simpler for the installer. The FAQs cover everything from the different choice of pitched roofing underlays available and the associated ventilation strategies for an impermeable roof covering, in accordance with BS 5250 and the latest NHBC Standards.
