Hi,
I am looking for some advice on whether or not an airtight Membrane in worth installing on the ceiling in my new build bungalow. I plan to airtight seal around doors and windows. I have a 6in cavity which will be pumped and I'm going to put thermal slabs on the inside off the exterior walls.

Also, Is HRV worth installing still without the airtight membrane installed.
Thanks.
