I'm sure a question asked allot.
If one is after dg thermally broken aluminium windows is there a rough m2 rate (supply only)?
Does one have a guide for the comfort glass or low e per m2 instead of dg?
When I have a client being told low e glass is better than dg, I need empirical evidence to support such a statement.
Many thanks
Merry Xmas to all
