Advantages / Demilec, your natural insulation and environmentally friendly spray foam, Liège et Wallonie
1. Airtightness
Soudal SPF O3 foam covers even the smallest holes or cavities and leaves no room for air in its holder, in contrast to fibrous insulation (glass wool, rock wool, ...). Indeed, in cases of poor air tightness, insulation can lose up to 5 times its effectiveness (according to IBP Stuttgart).
Poor air tightness will create areas of condensation (thermal bridges) with consequences such as odors, mold and heat loss!
2.Thermal insulation continuous and seamless
The spray foam makes it possible to thermally insulate a building on an ongoing basis: the spray foam has no joints, a major source of heat loss.
Soudal SPF O3 diffuse water vapor while being airtight.
3. Acoustic insulation
