We have an integrated double garage which has no insulation, and lots of gaps down the sides of the garage doors, etc. Gets very cold and dusty. Since I want to relocate the freezer in there, I need to raise the temperature and make the space generally nicer and cleaner.
Was starting to research insulated garage doors, when I realised that the catnic lintels we have in there are full of holes. Not sure if these are actual vents or just holes to make the piece of steel lighter? They vent horizontally and then downwards to the outside.
Does anyone know if I need these holes to be there? Any reason I shouldn't cut a panel of Celotex and slot it in over the inside surface? Or is there something more effective I could do like fill the lintel with foam? (Not sure that I can get access to it)
Thanks.
