So about to start adding insulation to my suspended floor couple of questions.
1. Can pir board touch the external walls. I am guessing not so plan to put a bit of dpc between wall and board.
2. Can expanding foam touch exterior walls.. guessing not so again will add some doc.
3. What is the best foam to use.
4. Will I notice much of a difference between 50mm v 75mm board. Cant use 100 due to air flow.
Thanks
