Start your journey to net zero by thinking fabric first

With one of the most innovative combinations of reflective and air tightness membranes available, our technical experts can help you value engineer your project to meet energy efficiency targets.

Get ahead of the game

Construction membranes

In order to meet demanding fabric energy efficiency targets and the more onerous Building Regulations, the building’s wall construction should combine a thermally efficient and airtight solution.

Glidevale Protect’s unrivalled construction membrane offering includes a range of reflective, insulating membranes for use on the warm and cold side of the insulation to improve the overall thermal resistance of the wall and meet low U-value targets.

This includes our high performance air and vapour control layers (AVCLs), which have been specially developed to facilitate high levels of air tightness, significantly reducing air leakage and improving energy efficiency in buildings.

Success Stories

Glidevale Protect’s air tightness products and reflective external wall membranes work particularly well together to support stringent low carbon and Passivhaus type designs. Read about how a combination of membranes helped Scotland’s first multi-story building achieve Passivhaus standard here.


Our innovative, zero energy ventilation solutions are simple methods for condensation control in homes, which complement any fabric first approach. The Intelligent Passive Stack Ventilation System (iPSV) is natural passive stack with a difference. As a fully automatic solution, it opens and closes depending on relative humidity levels, ensuring the correct ventilation levels are maintained.
