RHS-Felt Retrofitting Seal 80-150

Description: Pass-through seal for square pipes installed on a felt roof ​while retrofitting. The weather- and ozone-resistant properties of EPDM rubber are the best possible, and it can endure continuous heat stress of +90°C (and intermittently up to +150°C). EPDM rubber also tolerates the acids and alkalis often found in the air in industrial areas. Should be installed with hot bitumen between two felt layers. Pass-through seals are recommended to use on flat roofs (< 11,5° slope). Contents: Seal.
