Solution for a flat roof on corrugated steel deck with one-layer polymer-bitumen membrane and stone wool insulation

AREA OF APPLICATION

Buildings with a large area and minimal equipment on the roof, logistic centers, warehouses.

SOLUTION DESCRIPTION

This is an excellent solution for large area roofs and prefabricated buildings and structures. The system with waterproofing in one layer significantly increases the speed of installation of the roof. The use of materials with high fire resistance provides additional safety and durability of the building.

The roofing covering consists of one layer of polymer-bitumen membrane with elongation not less than 30%, tensile strength not less than 600 N/50mm and tear resistance not less than 200N.

Two grades of stone wool thermal insulation are used for the thermal insulation layer: TECHNOROOF CS(10)60 is a more durable thermal insulation used for the upper thermal insulation layer, which distributes the external load to the lower thermal insulation layer; TECHNOROOF CS(10)30 slabs have lower compressive strength and are used for the lower thermal insulation layer. For formation of slopes and counter-slopes on the roof the TECHNOROOF CS(10)40 Slope stone wool slabs are used.

As a vapor barrier on profiled sheeting, Vaporstop CA 500 or CA 1000 self-adhesive aluminized membranes are used, which have high vapor barrier properties (including the points where fasteners are installed), is resistant to mechanical impacts and can bear the weight of a person.

• Vaporstop CA 500 is used in buildings with dry and normal humidity conditions of interior spaces;
• Vaporstop CA 1000 is used in buildings with all humidity conditions of interior spaces, including damp and wet conditions.

Insulation and waterproofing layers are mechanically fixed to the base with telescopic fasteners.
