A product line designed to resolve all waterproofing needs
A LINE OF PRODUCTS DESIGNED TO SOLVE EVERY WATERPROOFING NEED
The WINGUM PLUS® H₂O system is available in different colors and performance versions:
REFLEX (reflective)
Reduces roof temperature by up to 50% compared to traditional bituminous membranes, offering several advantages:
- Far greater roofing durability over time since roofing is not subject to high temperatures.
- Greater efficiency of solar panels which normally suffer from excessive heat conditions.
- Internal temperatures inside buildings are directly improved during summer months when temperatures are much higher.
RAPID
Provides fast rain-proof protection only 4 hours after application at 20° C, allowing quick project completion and “wet-on-wet” application. Ideal for small areas, fast interventions, and complex geometries.
BROOF T2
For roofs with solar panel installations, Winkler has developed a Broof t2 certified version according to UNI EN 13501-5 – standards for external fire exposure, also available in reflective variant.
