Why Permavent was chosen

Permavent APEX was chosen thanks to it’s high vapour-and-air permeability, reducing condensation and allowing for excellent heat transfer without the need for additional ventilation at low or high levels of the roof. This is especially important around solar installations, that by design trap and hold heat.

This allowed for the installation of number of photovoltaic panels in an array across the roof that will use sunlight to generate free, clean electricity thereby powering the home in a sustainable and less environmentally impacting way.

Sandtoft Neo clay pan tiles were used to set off the contrasting flat roofs finished in a GRP coating with a dark Anthracite colour.

Branch Manager at SIG Roofing, Adrian Dann, believes in the quality and value for money of Permavent underlays, along with the technical support provided by Permavent.

How Permavent Products were installed:

Permavent APEX was installed as per the manufacturer’s instructions and building standards regulations, in compliance with BS5534 & BS5250.
