The cool roofing solution
A proven technology, a professional application, a measurable result.
How does it work?
A dark roof absorbs up to 90% of solar radiation. That energy turns into heat, which then enters the building.
The cool roofing coating reverses this. Its high solar-reflectance formulation sends most of the radiation back, while its thermal emissivity releases residual heat.
The result: your roof stays close to ambient temperature, even under direct sun.
A coating built for performance and longevity
Coolaris applies exclusively the cool roofing paint from Mon Toit Frais, a French manufacturer renowned for the excellence of its formulation. A coating at the top of the market: ultra-high-reflectance pigments, durable technical binders, and anti-UV additives that preserve performance over time.
Anti-UV and anti-soiling additives
Reflective performance preserved over time.
Multi-layer application
Layered system ensuring thickness and homogeneity.
Why cool roofing is becoming standard
Energy performance
Direct reduction of thermal load on the building and the cooling system.
Indoor comfort
More stable temperatures, fewer peaks, better environmental quality.
Roof protection
Fewer thermal cycles, longer lifespan for the waterproofing layer.
Non-intrusive solution
No structural overload, application possible on an occupied site.
Reversible and serviceable
The system can be locally retouched or refurbished if needed.
Environmental commitment
Direct reduction of cooling-related emissions.
What changes in practice
| Criterion | Standard dark roof | Coolaris-treated roof |
|---|---|---|
