Ventilated Roofing Foam for Moisture and Airflow Control

What is Airflo Ventilated Foam?

Airflo Ventilated foam is a combination of a lightweight, open-cell polyurethane and a closed-cell polyethylene (PE) foam. 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.
