Olympia Steel Buildings Foam Closures and Eave Trim For Pre-engineered Steel Buildings and Prefab Metal Buildings
A foam closure strip is mounted on top of the eave strut of the steel building to seal the building against moisture and leaks. Because the inside foam closure strip has the same profile as the roof sheeting, when the roof is attached to the building a tight seal is created against air infiltration, saving money on heating and cooling costs. For additional protection against leaks, an outside foam closure is attached to the outside steel building wall panel. To secure the entire assembly a metal eave trim closure is placed over the outside foam closure. The top of the metal eave closure has the same configuration as the roof sheeting, therefore where the metal eave closure meets the roof it creates a tight seal preventing leaks.
Olympia Steel Competition’s Metal Building Foam Closures
Other metal buildings companies only use top foam inside closures. There is no foam outside closure and no metal eave trim closure. This allows the building to leak at the eave and the insulation to become wet causing the insulation to sag. Ultimately, the insulation WILL need to be replaced.
