Hi and thanks for reading, timber frame due to go up in a couple of weeks, our plans show overkill in our opinion on roof insulation, It's a dormer so habitable roof space and our plans show tlx gold under rafters, then 150mm celotex and a further 38mm of kingspan, we have been told this is overkill and very pricey!!! We need to achieve uv 0.16 in roof any better suggestions? Many thanks
