ONDUTISS AIR
BBA certified high vapour permeable roof membranes in a range of grammages (100 - 160) | 1x50m /1.5x50m
ONDUTISS AIR
The ONDUTISS AIR range comprises high-performance, vapour-permeable membranes engineered to enhance the waterproofing integrity of roofs and buildings.
Suitable for both cold and warm roof applications, these membranes are crucial for comprehensive moisture management. Optimal Condensation Control & Waterproofing: It is best practice to install a breathable membrane, such as ONDUTISS AIR, beneath Onduline roofing sheets, tiles, and BARDOLINE roof shingles. This ensures robust protection against condensation buildup, contributing to maximum waterproofing performance and long-term roof health.
ONDUTISS AIR membranes are available in various weights to suit diverse project requirements, from 100 gsm and 120 gsm to premium 140 gsm and 160 gsm options. Higher grammage indicates superior tensile strength and enhanced durability for demanding applications.

The ONDUTISS AIR range of high-performance membranes is engineered to provide superior moisture management for roofs and buildings. Designed for both warm and cold roof applications, these vapour-permeable membranes are essential for ensuring the long-term health and waterproofing integrity of your structure.
While the membranes are completely waterproof, preventing liquid rain and snow from entering the roof structure, their unique composition allows water vapour to pass through. This is essential for proper moisture management.
While the membranes are completely waterproof, preventing liquid rain and snow from entering the roof structure, their unique composition allows water vapour to pass through. This is essential for proper moisture management.
How it Works: In every building, moisture is generated from daily activities like cooking, showering, and even breathing. This moisture, in the form of water vapour, naturally rises and tries to escape through the roof. If it hits a non-breathable layer, it condenses back into liquid water. Over time, this condensation can cause significant problems, including dampness, mold, and damage to the roof's timber structure and insulation. ONDUTISS AIR acts as a crucial barrier, blocking external water while allowing internal water vapour to escape, preventing this destructive condensation cycle.
A "Breather" for Your Roof: By letting the roof "breathe," ONDUTISS AIR helps maintain a dry, healthy environment within the roof space. This also helps to preserve the effectiveness of your insulation, which can be compromised by moisture.
The ONDUTISS AIR range offers a selection of products designed for different applications and performance needs. The grammage (gsm) of the membrane is a key indicator of its strength and durability.
100 gsm & 120 gsm: These lighter membranes are perfect for general-purpose applications like sheds, carports, and residential roofs where you need reliable waterproofing and condensation control. They provide an excellent balance of performance and value.
140 gsm & 160 gsm: These are the professional's choice for more demanding environments. The higher grammage translates to superior tensile strength and tear resistance. This is especially important for commercial, industrial, or agricultural buildings where the roof may be exposed to greater stress during installation and throughout its lifespan. These premium options offer enhanced durability and peace of mind for long-term projects.
