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 principle

Four effects, one product

Reflect the sun

The micro-spheres bounce back over 90% of solar radiation (up to 86% of infrared) before it heats the building.

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.

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

  1. 1Thorough cleaning (detergent, brush, water)
  2. 2Apply one primer coat, let it dry
  3. 32 to 3 coats of ThermBlock

Sheet metal

  1. 1Cleaning / stripping of the old system
  2. 2Treat sensitive points (bolts, parapets) with bands
  3. 3Anti-rust where needed, then ThermBlock

Waterproof tarpaulin

  1. 1Apply ThermBase for adhesion
  2. 2Let it dry completely
  3. 3Apply ThermBlock
