| Premolded Corners- for consistent, worry-free inside & outside corners of single ply roofing. Premolded corners provide a guaranteed, uniform, permanent corner seal. Portals Plus Premolded Corners eliminate the cutting, folding, stretching, and cementing of membrane and base flashing materials into unnatural shapes. All edges on the Corners are feathered to allow the best posssible adhesion without the fear of curling edges. All Portals Plus Premolded Corners are seamless molded construction and available for both inside and outside corners. Premolded Corners reduce the high cost of roofing installation and the even higher cost of callbacks due to leaks. |
