TERMORASANTE AEROGEL is a thermal bridging regulator, anti-condensation, anti-mold, highly reflective and breathable lime thermal finishing plaster.

The application of a thin (4 - 10 mm) finishing coat can raise the surface temperature of walls by 3 to 5 °C. Thanks to its excellent heat reflectance, it creates a high thermal comfort in the room.

It can be used for any type of new construction, as well as during the restoration, renovation or refurbishment of old buildings, including of solid stone walls.

Typical Applications

Thermal insulation
Thermal bridging regulator
