When installing STRUCTASEAL® EPDM roofing, the inner corners are folded and fixed. This is possible because sufficient EPDM membrane is available at this angle. For external corners this is different and it is recommended to work with prefabricated EPDM corners. These are available in two variants:
The external corner 45º external corner is used to seal skylights etc. The STRUCTASEAL® prefabricated EPDM external corners are applied in combination with Contact Adhesive and the MS Polymer.
