Hi
I am in the process of new build
About to put in floor insulation and underfloor heating and liquid screed.
when I got planning the regs were 60mm of polyiso (foam insulation) but now they have increased dramatically
I do not have the space to install deeper insulation as the sub-floor is in place.
Is there any better insulation on the market that would meet new 2008 regs for a house with underfloor heating?
Is there foam insulation that can be got in 30mm thickness - I was considering 2X30mm in an effert to reduced thermal bridging ?
ta in advance
