What Are ONDULINE Classic Vented Foam Fillers Used For?

ONDULINE Classic Vented Foam Fillers are designed to close the corrugation gaps beneath roofing sheets while maintaining ventilation through the roof structure.

Corrugated roofing sheets naturally create openings where the raised profile meets the supporting roof structure. These gaps can allow rain, dust, draughts and debris to enter if left unprotected.

Vented foam fillers help reduce these openings without completely restricting airflow, making them particularly useful where roof ventilation is required.

Common applications include:

• Garden Sheds: Helps protect stored tools and equipment while allowing ventilation through the roof structure.
• Garages and Workshops: Reduces exposed corrugation gaps and supports airflow beneath the roofing.
• Summerhouses and Garden Buildings: Helps maintain ventilation while improving protection against wind-driven moisture.
• Stables and Animal Shelters: Provides additional protection against dust, debris and wind-driven rain.
• Agricultural Outbuildings: Suitable for barns, storage buildings and utility structures requiring ventilated roof details.
• Wood Stores and Storage Buildings: Supports airflow while reducing unwanted gaps around the roof covering.
• Roof Repairs and Refurbishments: Suitable for replacing existing vented foam fillers on compatible ONDULINE Classic roofing systems.

Vented vs Non-Vented Corrugated Roofing Foam Fillers

Choosing between vented and non-vented foam fillers depends on the ventilation requirements of the roof structure.

Vented foam fillers are designed to maintain airflow while helping prevent unwanted debris and wind-driven rain from entering the roof space.

Non-vented foam fillers provide a more complete closure of the corrugation gaps where ventilation is not required through those openings.

Always follow the roofing manufacturer’s recommendations when selecting vented or non-vented fillers.

Technical Specifications

Installation Guidance

ONDULINE Classic Vented Foam Fillers are designed for straightforward installation beneath compatible corrugated bitumen roofing sheets.

For effective weather protection and ventilation:

1. Prepare the Roof Area: Ensure the eaves or ridge area is clean and ready for installation.
2. Position the Foam Filler: Place the filler beneath the roofing sheet, aligning its shape with the ONDULINE Classic corrugated profile.
3. Check the Fit: Ensure the foam follows the corrugations and closes the intended gaps.
4. Maintain Ventilation: Ensure the ventilation openings remain unobstructed.
5. Install the Roofing Sheets: Secure the roofing sheets using the manufacturer’s recommended fixing method.
6. Inspect the Finished Installation: Check that the foam fillers remain correctly positioned and that airflow paths have not been blocked.

Important: Vented foam fillers should not be used as a substitute for properly designed roof ventilation. The required ventilation area and positioning should be established in accordance with the roof design and manufacturer’s guidance.
