Hi
We have received our full plans back from the architect and we have endless amounts of Celotex needed.
They said:
70mm Celotex CG50000 cavity wall: 0.19 uvalue when finished
70mm Celotex FR5000 ground insulation: 0.20 uvalue
150mm Celotex FR5000 roof insulation and 40mm Celotex GD5040 under rafters: 0.13 uvalue
120mm Celotex FR5000 for ceiling and 60mm Celotex FR5000 for joists: 0.14 uvalue
A quote for this from our local builders merchant was over £5000 oh my gosh!!
Are there any alternatives that reach the same uvalues?? I have heard people mentioning getting seconds... do inspectors frown upon this?
Many thanks
