WATERPROOFING WITH HEAT-APPLIED BITUMINOUS MEMBRANE AND REFLECTIVE PROTECTION
Warm roof with thermalinsulation panel, waterproofed with a double layer of smooth bituminous membrane, applied hot, completed with a protective, reflective liquid coating, resistant to water stagnation and suitable for the application of new membranes
1 SUPPORT / LOAD-BEARING ELEMENT
It must have a minimum slope of 1%. Alternatively, a sloping screed can be created using WINPLAN 370 or WINPLAN PRO. For bonded screeds with a thickness between 1 and 3 cm, it is recommended to use WINGRIP® NEXT as a fresh-on-fresh adhesion promoter.
2 PRIMER
Roller, brush or spray of the bituminous primer ECOIMPRIMER, with a total consumption 150–200 g/m².
3 VAPOR BARRIER
Hot application of the COVERBLOCK 4 mm bitumen-polymer membrane, which functions as a vapor barrier and is reinforced with a glass–fiber mat coupled with rot-proof aluminum foil.
4 ADHESIVE FOR INSULATION BOARDS
Roller or brush application of the water-based bituminous adhesive WINGLUE or WINGLUE FAST,
with a Consumption of 0.8 kg/m².
5 THERMAL INSULATION ELEMENT
suitable for torch application of bituminous membranes.
6 WATERPROOFING (FIRST LAYER)
First layer of EXPERTA 300 elastoplastomeric (BPP) bituminous membrane applied by torch, featuring cold flexibility of –15 °C and reinforced with a rot-proof continuous-filament polyester non-woven fabric stabilized with glass.
7 WATERPROOFING (SECOND LAYER)
Second layer of EXPERTA 400 elastoplastomeric (BPP) bituminous membrane applied by torch, featuring cold flexibility of –20 °C and reinforced with a rot-proof continuous-filament polyester non-woven fabric stabilized with glass.
