Hello all,
I've just laid the OSB3 flooring for a garden room build and I've included 2mm expansion gaps as suggested in nearly everything I read about OSB. I have a question though ... can I fill those gaps with something flexible like silicon, expanding glue, or tape to help keep the building airtight?
I'll also be putting OSB wall sheathing and roofing.
Or am I worrying about nothing?
Thanks for your advice everyone, and sorry for the rookie question.
