EPDM Pre-Formed Internal Roof Corner is designed for larger 90° internal junctions requiring increased coverage around the adjoining roof surfaces and upstands. The 150 × 150 × 200 mm profile provides a generous bonding area, helping create a dependable waterproof connection at critical roof details.

Its factory-formed shape simplifies installation and reduces the need to cut and fold EPDM membrane into complex internal corners. Flexible 1.2 mm EPDM accommodates normal movement while providing a clean and consistent finish.

Suitable for residential, commercial and industrial flat roofing, the corner can be incorporated into new EPDM installations or used when refurbishing existing compatible roof details. Install using the appropriate EPDM adhesive and sealant.
