The advantages of
Cool Roofing
thermal confort
Our cool roofing solution reduces surface temperatures, lowering the interior temperature of your building by up to 10°C in summer.


air conditioning usage
Stop wasting money on air conditioning! Save on your energy consumption while extending the lifespan of your systems.
carbon footprint
Our solution helps fight global warming. Passive air conditioning avoids urban heat islands (UHI), while reducing the carbon footprint of your infrastructure.
solar panel roofs
Our technologies integrate perfectly with your solar panels. Enhance their performance by combining reflectance and photovoltaics for even more optimized energy management.

How Cool Roofing
actually works
Without
Drylast
Heat is absorbed by the roof. The building heats up. Air conditioning drastically increases energy consumption.
With
Drylast
Sunlight is reflected back into the atmosphere. The building reduces its energy consumption through passive air conditioning.

Two layers of acrylic primers. One layer of white paint and a top coat on the surface, preventing any further adhesion. These layers are not UV resistant and crack quickly.
cool roof technology
A single layer of polysiloxanes that stands out for its unique characteristics : a very high solids content of 95%, an elongation of 500%, and extreme resistance to weathering.
