Taping Celotex Joints

lagi

I am fitting some celotex between my eaves and then overlapping some more across the eaves.Bought some silver tape to help with insulation but should i tape all joints or just the final layer?

Can i bump this up, getting to second layer now.

I would tape all the joints if I were you. If air can get past the insulation, there's not much point in having it. I tried the silver tape with limited success, I found the best way was gaffer tape or duct tape, then put the silver stuff on top of that. Gives a much stronger joint and you still have the reflecting silver bit.

I always tape all the joins.
