A brief overview of the advantages of outdoor vent covers:
-
protects against precipitation
-
protects against insects and rodents
-
prevents cold air from entering the system when it is switched off, thus avoiding cold air and condensation on the outside of the system in the event of a cold
-
protects against wind - especially vent covers with backdraft stopper and hood
-
protects against solar radiation
Here are some examples of the correct installation of a ventilation system for exhaust air.
-
we recommend using plastic or insulated antibacterial ducts
-
install backdraft stopper designed to mount completely inside the duct in the outside wall duct, approximately in the middle of the duct, with the axis vertical
-
install an exterior vent cover with a valve on the outside of the external wall
-
install the duct in the outside wall with a 1-2° slope towards the outside, so that if condensation occurs inside the system, it will not accumulate in the duct and will flow outside
-
install
Briefly summarise the advantages of this system: the installation of plastic or insulated antibacterial ducts provides maximum airflow with minimum resistance and silence, the installation of a duct in a wall with a slope will not accumulate condensation, the installation of a two-valve system (one inside the duct and one in the outdoor ventilation grille) will provide maximum protection from cold and from the build-up of condensation on the outside of the duct.

-
install an exhaust vent cover with a backdraught shutter on the outside of the wall
The advantages of this system are identical to those of the cooker hood system - backdraught shutters in the duct provide protection against frost and prevent condensation from accumulating.
