I would like to know the maximum U-value that I could use for installing wall or floor in London.
I show you the Italian U-value table.
Zona climatica= climatic zone
struttura opache verticali= vertical wall
struttura opache orizzontali=floor
Exists a UK table like this?
Thanks you in advanced!

Limiting U values for the elements you requested under 2013 Part L:
0.18 for a wall
0.13 for a floor
So you will need a lot more insulation to achieve those U-values than for the U-values listed in the table you provided.Last edited by jrhartley; 08-02-2016 at 20:10.
