Thematic glossary for decision-makers

Under-slab insulation

A process consisting of placing an insulating material under a slab on grade to limit the building's heat loss.

Thermal conductivity

A material's ability to conduct heat, expressed here in mW/mK; the lower it is, the more insulating the material.

Acermi Certification

French label guaranteeing the performance and quality of thermal insulation according to recognized standards.
