The system
Japanese technology, a proven process.
ThermBlock doesn't stop heat through thickness, but through reflection. Here's how it works, and how it's applied on every type of surface.
The system, in cross-section
Three coats, one protection.
On your roof or façade, ThermBlock builds up in three complementary coats, each with a precise role, from the adhesion primer to the top coat.
ThermBase
Adhesion primerThe base coat that ensures perfect adhesion.
Coverage, ~100 m² / bidon 15 L
ThermBlock
Thermal insulation & waterproofingInsulation, waterproofing and solar reflection in a single product.
Coverage, ~30 à 45 m² / bidon 15 L
ThermTop
Top coatThe colorless top coat that enhances and protects the color.
Coverage, ~100 m² / bidon 15 L

The principle
Four effects, one product
Reflect the sun
The micro-spheres bounce back up to 86.2% of infrared radiation, the band that carries heat, and 84.9% of the full solar spectrum, before the building heats up.
Stop heat at the surface
A micro-porous, air-layered structure stops heat right at the surface: thickness is no longer the deciding factor.
Flex without cracking
Over 200% elasticity follows the materials' expansion under temperature swings.
Stay 100% waterproof
The acrylic film provides lasting protection against water, humidity and mold.
Hybrid technology
Two liquids, two protections
When you open a pail, ThermBlock comes as two layers: a white liquid that protects against infrared, and a clear liquid that protects against ultraviolet. Mixed together, they form an emulsion packed with millions of hollow acrylic micro-spheres.

Under the microscope
The difference shows at ×200.
Scanning electron microscope images. These are not diagrams: this is the material itself, photographed in cross-section.
×20The film in cross-section
The dry coating forms a continuous, even layer on the substrate. This thickness (DFT > 0.3 mm) carries the insulation and waterproofing.
×200The hollow micro-spheres
Close-up: the material is almost entirely made of air-filled hollow spheres, about 50% by volume. That is what reflects radiation and makes the product lighter than water.
The same ×200 view, across five coatings
At identical magnification, most reflective coatings show no hollow spheres at all.

Spheres present, film not flexible
COOL ONE
No spheres
ECO COOL
No spheres
MIRA COOL
Almost no spheres

Application
A process for each surface
Brush, roller or airless spray. 2 coats minimum, dry thickness > 0.3 mm. Apply between 5 and 35 °C, humidity < 85%.
Slab / concrete
- 1Thorough cleaning (detergent, brush, water)
- 2Apply one primer coat, let it dry
- 32 to 3 coats of ThermBlock
Sheet metal
- 1Cleaning / stripping of the old system
- 2Treat sensitive points (bolts, parapets) with bands
- 3Anti-rust where needed, then ThermBlock
Waterproof tarpaulin
- 1Apply ThermBase for adhesion
- 2Let it dry completely
- 3Apply ThermBlock
