Enlargement in cellular concrete: roofing




by airsp » 11/05/10, 23:46

Hello,

We are leaving to enlarge the house in aerated concrete.

We are offered a PES sandwich panel roof of 160MM (u = 0,22), without a high floor.

I wanted to make a high floor with creation of lost roofs and insulation of these roofs (glass wool 200 or 260mm).

Wouldn't it be cheaper?
What is this solution worth?

Thank you
