Bitumen polymer membrane rolls are the most widely used materials for flat and very flat roofs.
The new generation of bitumen roofing is made not of oxidized, but of polymer bitumen (APP or SBS) and with mechanical reinforcement – fiberglass or polyester. They are flexible and durable, suitable for a wide range of surfaces. The bitumen membrane is able to ensure water tightness even on completely straight surfaces.
Fusible materials are most often applied in two coats to new buildings, ensuring maximum effect and long-term durability of the roofing. And one layer is applied to the bitumen roof in case of renovation. Bitumen flat roofs are applied by heating with a gas burner.
