I will insulating a suspended timber floor as part of a new extension build. I need 200mm wool for my u value of 0.18
What are the main advantages to using insulation slabs over loft roll other than the the loft roll is quite a bit cheaper. Thermally the only difference is 0.040 loft roll - 0.037 slab.
Will I notice any difference using the slab compared to the roll to justify the extra cost.
And yes I know I could PIR but looking to keep cost down and will being using celotex for the walls.
Thanks in advance
