Foam infill strips (also called roof infill strips or foam fillers) are profiled foam seals designed to fill the gaps created by the shape of metal roofing sheets. These gaps naturally occur where roofing meets structures such as battens, flashings, gutters, ridges, and walls.
When installed correctly, foam infill strips help create a weather-tight, professional finish and are a critical detail in quality roofing installations.
Foam infill strips are commonly installed at:
Eaves and wall junctions
Ridge capping and barge flashing areas
Box gutters and apron flashings
Shed roofs, patios, carports, and verandahs
They are suitable for both residential and light commercial metal roofing projects.
Using the correct foam infill strip helps to:
Reduce wind-driven rain entering the roof cavity
Block dust, insects, birds, and vermin
Improve roof performance in exposed or coastal areas
Support long-term roof durability by limiting moisture ingress
They are especially important in Australian conditions, where wind and heavy rain can force water into unsealed roof gaps.
Our foam infill strips are profile-matched, meaning they are shaped to suit specific metal roofing profiles rather than being generic foam.
Available options include infill strips for:
Other common COLORBOND® and ZINCALUME® roof sheet profiles
Choosing the correct profile ensures a tighter seal and easier installation.
