Flat roofs

LamekatusedAs to flat roofs we use coil material based on APP and SBS bitumen and consider the climate of Northern Countries. The material also includes the produce of acknowledged German, Dutch, Lithuanian, Finnish and Russian companies. The installation of material uses either gas-welding or cold gluing method; the latter ensures safety in fire-risk environment. Bitumen coil materials can be installed on old bitumen coating, masonries, concrete and cement surfaces, and timber base and isolation plates of mineral wool. For new roofs and those needing additional thermal insulation we recommend two-layer thermal insulation with special dowels attached to roof ceiling, the top layer of which is load-bearing mineral wool plate with ventilation grooves, bottom layer is polystyrene or mineral wool, the thickness of which is determined separately for each particular roof according to thermal resistance calculations.
