Frequently Asked Questions (3)
Generally, breather membranes allow water vapour to escape from inside a building without the need for extra ventilation.
The thickness of a breather membrane will all depend on the project type. For example, 135gsm thickness membrane will be suitable for more advanced roofing projects.
It is widely recommended to use breather membrane is most roofing projects. However, in unique situations a non-breather membrane is more suitable.
Breather Membranes
Breather membranes, also known as breathable membranes, allow insulated structures to quickly release excess moisture vapour into the atmosphere and keep the internal components of wall and roof structures dry whilst fulfilling the task of a secondary protection membrane and preventing penetration by external environmental impurities such as dirt and rain. These membrane types are installed on the cold or exterior side of the insulation beneath the main outer building lining, roof tiles or cladding.
