    Hi,

    In a room there's 2 air vents (about 5cm wide, circular shape) in the wall. I want to block one of them atm, will unblock again in late Spring.

    What's the best material to use, to maximize prevention of air coming in?

    Thanks,
    Pa.

    A towel. Why do you want to block them?

    To keep the cold out and heat in. Previously used a towel but was wondering if I used something else would it be much more effective?

    Foam expanding spray gun or simply just cardboard and masking tape with a towel tucked in.

    If I use expanding foam it this easy to remove at a later date?

    A balloon will fill the gap and be easy to remove - blow it up in situ. Combined with cardboard and masking tape that should deal with most drafts.

    Yes. It will set as a kind of solid sponge structure and you can cut it or dig it out after in pieces.

    It sticks very solidly to the surfaces around it though so it will leave a small amount of film where it was stuck to the sides of the hole.

    Don't block vents without knowing what you're doing.
    What room?
    What's in the room?
    Is there a combustion appliance in the room?

    There's a stove fire in the (living) room. Coal and wood.

    Is the vent up or or down low?
    Is it a pipe or will blocking it up from the inside result in air still flowing in through a cavity.

    What’s the issue with it.? Might a external Louvre vent help ?

    :eek:
    Hope you have a working CO monitor and alarm so.

    Proceed with caution.

    Very unusual to have two vents in the one room. Are they close together? Is it possible that there used to be two rooms and that a partition was removed?

    Some non sealed stoves/gas fires require 2 vents in the room.

    Double checked- there's only 1 vent in the room
    The vent is a pipe, parallel to the group, round, pipe between it and the concrete.
    The stove is shut (as in not open fire), attached directly to chimney
    Have no CO monitor in the room....

    A high one for regular ventilation and a low one for rooms with CO source
