Proper Installation of Permavent Breathable Membranes
To ensure the effective performance of Permavent breathable membranes, it is crucial to follow the guidelines set forth in the BS 5534 Code of Practice. Installers must meticulously adhere to the relevant building regulations to guarantee compliance and satisfactory outcomes.
It is important to note that Permavent membranes serve as a secondary barrier against wind-driven rain and snow and should not be relied upon as the primary waterproofing layer. While these membranes can withstand UV exposure for up to 3 months, it is considered best practice to promptly install the primary waterproofing finish, such as slates or tiles.
During installation, it is essential to orient the Permavent membranes correctly, ensuring that the side with the Permavent logo is facing upward.
For applications involving tile and slate roofs, the membrane should be laid horizontally across the rafters, commencing at the eaves. Properly secure the membrane in place using either battens or membrane tape, taking care to maintain a secure and tight fit.
By following these installation instructions, you can maximize the effectiveness of Permavent breathable membranes and contribute to a reliable and resilient roofing system.
