    I had builders build a stud wall and insulate the roof in my garage - so I can work there (with a heater if required) in the winter

    Everything looks ok and I'm happy with the result

    But... I've just checked the edges of the stud wall that has had plaster boards put on...
    There's a draught coming in!!

    What do I do?
    How do I get rid of the draught?

    When getting advice about building a stud wall on this forum, I think someone mentioned foam that could be sprayed around the stud wall

    I can't find any spray foam
    The only thing I can find are stick on foam excluders - that you use for doors and windows

    What should I be looking for?

    Thanks

    Poke a screwdriver thru the plasterboard and poke foam tube thru to seal, small hole to fill when set.

    thanks for the reply - i haven't been able to reply until now
    not sure if this would work

    the air is coming through the side gaps. see the following pic:

    any ideas?

    the only logical thing i can think of is removing the plaster boards and applying expansion foam - but just afraid i might have trouble putting boards back if the foam has set

    suggestion: would it be a good idea to take off plaster boards, apply foam and then quickly put boards back - allowing the foam to seal?
    is that a good or bad idea?

    also: would it be a good idea to apply foam on the other side of the garage door? the concern here is that the foam would stick out and not look very nice?

    any advice would be great

    thanks

    ok... this sounds a lot better solution to me - will be much neater
    and given that the wall won't be moving, caulk should be ok

    would u recommend anything on the outside - the garage door itself?
    i'll take a pic of this later and will update this post
    thanks

    EDIT: i've just taken a pic of the garage door to illustrate

    the gap is all around the garage door - behind it is now insulation material contained within a stud wall

    can i, should i do anything about the gap on this side?

    see below for the pic i took:

    You could put up timber frame to seal or use foam.

    @foxhole, i think i'd like to use foam - but am just afraid what it will turn out like
    just want to know if is easy to sculpture before it fully dries
    importantly: if i make a complete mess, how easy is it to remove?

    thanks

    You don't touch it before it dries, once dry can be carved easily [bread knife can be used].Spray area with water before foam as it helps it expand, use sparingly you will find it expands far further than anticipated, don't be in a hurry to trim any still wet will make a mess.[/b]
