ᐅ Installation of Decentralized Blauberg Ventilators – Which Expanding Foam to Use?

Hello everyone,

We will soon be installing our decentralized ventilation system. We chose the Blauberg Vento fans because of their excellent heat recovery efficiency...

Which mounting foam should be used to seal between the drilled hole and the fan? Is there a particularly insulating type?

Thank you very much for your answers.

Good luck. Christian

It is important to use a non-expanding two-component foam here. These foams are also used for installing windows and doors.
