Condensation control

As buildings are increasingly designed to be more airtight and energy efficient, it’s important to achieve the correct balance of ventilation and aid the occupier health and well being. Left unchecked, the build-up of harmful condensation can lead to mould and mildew which damages interior decoration.


Glidevale Protect’s comprehensive range of airtightness solutions include air and vapour control layers (AVCLs), air barriers, a range of loft access hatches and sealing tapes. As the requirement for increased airtightness in buildings intensifies in order to address the global challenges of climate change, a fabric first approach from Glidevale Protect ensures full compliance to the latest regulations, including Passivhaus, helping to deliver low carbon designs and improved energy efficiency.
