Verge Trim & Oversills

Our range of verge trim products are specifically designed for installation under windowsills and where the roof meets the insulation. We have a selection of verge trims in different shapes and sizes to suit various connection purposes. Our range of oversills are designed to extend the length of an existing windowsill. This ensures that the windowsill overhangs the insulation and that no water ingress can accumulate behind the insulation system. Our oversills come in different depths, making them a versatile addition to your insulation project.
