Hi
New here and new to diy, apologize in advance if I dont use the correct terms for everything, I ll try my best to put the right words to the right things.
I am putting 100mm celotex insation boards between the horizontal joists in my garage, thus creating a ceiling.
My question is, do I need to dot the boards of air vent to keep some degree of air flowing between the lower space and the above ?
I am not looking into making my garage a leavable area, and the only things that will go above the ceiling for storage are mostly xmas decorations... Just trying to keep the temperature above freezing in winter.
thank you
