The base layer is a polyethylene foam, which provides strength and stability during installation. The profiled open-cell polyurethane layer allows the foam to breathe by permitting moisture and airflow to pass through its open-cell structure. This enables ventilation into the roofing system while maintaining a secure seal. ## **How It Works** Ventilated foam is designed to seal roof gaps while still allowing airflow. The closed-cell PE base creates a firm, supportive structure that fits securely into roof profiles, while the open-cell polyurethane section allows air and moisture vapour to move through the foam. This helps ventilate the roof cavity, reducing condensation build-up and improving overall roof performance. ## **Key Benefits** - **Promotes roof ventilation:** Allows airflow into the roofing system to help regulate temperature and reduce condensation. - **Manages moisture:** Enables moisture vapour to escape, reducing the risk of mould, timber decay, and corrosion. - **Strong and stable:** The closed-cell PE base provides durability and structural support during installation. - **Protects against the elements:** Helps prevent wind-driven rain, debris, insects, and pests from entering the roof space. - **Easy to install:** Lightweight and flexible, making it simple to fit on site. ## **Typical Uses** Ventilated foam is commonly used in roofing applications where ventilation and weather protection are both required, including: - Roof eaves - Roof ridges - Roofing junctions and cavities - Residential and commercial metal roofing systems It is suitable for projects where condensation control, airflow, and protection from external elements are important. --- Image ![BB900- Profile Ventilated](/sites/default/files/2026-01/Airflo-%20BB900-%20Profile%20Ventilated%20.jpg) ## Installation - Ventilated foam is quick and easy to install: - Ensure the installation surface is clean, dry, and free from debris. - Measure and cut the ventilated foam to the required length. - Position the foam into the roof profile at the eaves or ridge. - Secure in place as required before installing the roofing material.
