Waterproofing with cold bituminous membranes

Warm roof with heat-insulating panel, waterproofed by a double layer of cold-applied bituminous membrane with Winglue adhesive, laid under ballast.

1 SUBSTRATE / LOAD-BEARING ELEMENT

must have a minimum slope of 1%. Alternatively, a sloped screed can be created using WINPLAN 370 or WINPLAN PRO. For bonded screeds with a thickness from 1 to 3 cm, it is recommended to use WINGRIP NEXT as a fresh-on-fresh bonding promoter.

2 PRIMER

apply bituminous primer ECOIMPRIMER by roller, brush, or spray, with a consumption of 150–200 g/m².

3 VAPOR BARRIER

Hot application of the 4 mm COVERBLOCK bitumen–polymer membrane, which acts as a vapour barrier and is reinforced with a fiberglass mat coupled with a rot-proof aluminium sheet.

4 ADHESIVE FOR PANELS

Application by roller or brush of the water-based bituminous adhesive WINGLUE or WINGLUE FAST, with a consumption of 0.8 kg/m².

5 THERMAL INSULATION ELEMENT

6 ADHESIVE FOR MEMBRANES

Application by roller or brush of the water-based bituminous adhesive WINGLUE or WINGLUE FAST, with a consumption of 0.8 kg/m².

7 WATERPROOFING

COVERGUM SPECIAL elastoplastomeric (BPP) bituminous membrane with cold flexibility of –20 °C, applied cold with a suitable adhesive. The membrane is reinforced with non-woven continuous-filament polyester stabilized with glass, rot-proof.

8 VERTICAL UPSTAND WATERPROOFING

Construction of the vertical upstand of the waterproofing by hot application of COVERGUM SPECIAL elastoplastomeric (BPP) bituminous membrane, with cold flexibility of –20 °C. The membrane is reinforced with non-woven continuous-filament polyester stabilized with glass, rot-proof.

9 FLASHING

Installation of flashing for the fastening, protection, and sealing of the vertical upstand of the bituminous membrane.
