Product description

Flat Roof Pipe Sealing

Alfa Flat Roof Sleeves are water-repellent and ageing-resistant while providing strain relief, which makes them the perfect solution for the fast and durable sealing of tube penetrations through flat roofs. The elastic rubber (EPDM) collar is extremely resistant to humidity and ageing and withstands even high temperatures. The attached square flange is covered with butyl adhesive which is highly ageing resistant and guarantees a reliable, tight sealing.

The sleeve is applied with the rubber collar facing downward so it is flush with the adjacant areas and does not pose a tripping hazard. The elastic rubber accomodates buidling movements and relieves strain in the sealed area. The pipe flashing protects the building from damages caused by unregulated air exchange. It is used on walls, floors and special buidling components. The aluminium/butyl flange can also be glued to bituminous felts.
