Cold air from loft vent (moved to new thread)

[NewHomeOwner93]

The loft vent is letting freezing air into the upstairs landing, it can get pretty chilly.
I need to change this vent pictured or adjust it somehow.
If i can identify the brand or version it is I can then do something to stop the cold coming in.
Any ideas folks would be appreciated.

Hello, just came across this post whilst searching for solutions to the same problem you have! We have the exact same vent in the landing and it’s causing quite a chill. Just wondering, what solution did you find for it? Thanks.

It's always best to start your own thread, rather than jumping on an old one!

Could you post a photo of your vent?

The OPs vent was one typical of a PIV (positive input ventilation) system, and shouldn't be blocked up.
These systems are installed to reduce condensation and mold problems.
They may let cool air in from the loft, but that coolness should only affect a small area around the vent; the benefit of little condensation, usually outweighs the small amount of extra heating required.
Many of these units also have a small built-in heater that raises the temperature of the incoming air slightly in cooler weather.
