The White Roof Strategy: Reducing AC Bills with UV Waterproofing
In Malta, a traditional black bitumen roof can reach temperatures of 80°C in August. This heat radiates down into the penthouse, forcing AC units to run at max capacity.
The Physics: Black absorbs UV radiation. White reflects it. A "Cool Roof" can lower internal ceiling temperatures by up to 5°C.
The Solution: ZNR WP 2K UV
Old liquid membranes crack under the Mediterranean sun because UV rays break down the polymers. ZNR has engineered WP 2K UV specifically for high-exposure zones.
Why it beats traditional Liquid Membrane:
- Elasticity: It stretches 150% without snapping (vital for thermal expansion).
- Reflectivity: Pure white finish acts as a thermal shield.
- Walkability: Handles foot traffic for roof maintenance.
Application Protocol
Don't just paint over dirt. The substrate must be primed with ZNR P 200 Acrylic Primer to ensure the membrane bonds chemically to the concrete.
