Cool roof coatings.
For professionals.

Covalba markets 4 Cool Roof systems for renovation:

• Liquid coating: for all types of roofs
• Liquid waterproofing: for bitumen membranes, concrete, tiles, EPDM, PVC, etc.
• Anti-corrosion paint: for corroded metal roofs
• Solar lacquer: for skylights and skydomes

For new construction or roof waterproofing replacement, choose a white waterproofing membrane.

Cool Roofs help mitigate global warming, reduce the effect of urban heat islands, increase indoor thermal comfort and reduce energy requirements.

Key benefits include

• Less heat inside the building.
• Reduced energy costs for summer air-conditioning in certain types of building.
• Reduced greenhouse gas emissions thanks to lower energy consumption.
• 50% reduction in the building's impact on urban heat islands, limiting air pollution, health risks and power consumption peaks.
• By retaining less heat, the white roof improves the longevity of the waterproofing complex.

A single-sided photovoltaic system on a dark roof loses yield in the hot season. Studies have shown that single-sided panels installed on a cooler roof, e.g. with a white or green roof, can increase yield by around 10%.

As for two-sided photovoltaic installations, their yield will also increase by 20% to 25%, thanks to the action of the reflective paint, which not only reduces the temperature experienced by the panel, but also reflects more light towards it (albedo).
