What is low-emissivity (Low-E) glazing ?
cutting-edge technology :
thermal bridges for enhanced performance.
The advantages of low-emissivity glazing
In summer, it prevents overheating by controlling solar heat gain.
reducing your energy footprint.
In short, more light, less heat loss and better insulation.

Focus on therm 1.1 glazing
Therm 1.1 glass is a reinforced thermal insulation glazing (ITR) that combines high energy performance with optimal transparency. Produced by cathodic spraying and laser crystallisation, it provides natural light while limiting heat loss. With a Ug value of 1.1 W/m²°K (double glazing with a 16 mm argon gap), it meets the requirements of bioclimatic projects.
Difference between Therm 1.0 and Therm 1.1
Therm 1.1 offers transparency comparable to clear glass, with a solar factor of 65%, allowing free solar energy to be captured. It combines thermal performance (Ug of 1.1 W/m²°K) and visual comfort. Therm 1.0, with a Ug of 1.0 W/m²°K, has an even more efficient coating for energy-efficient projects.

|---|---|---|---|---|---|
| THERM 1.1 | 82% | 11% | 65% | 1.4 W/m²K | 1.1 W/m²K |
| THERM 1.0 | 70% | 22% | 49% | 1.3 W/m²K | 1.0 W/m²K |
