U Values

[PhillVR6]

After the suprising amount of usefull advice I recieved on my windows thread, do any of you have any suggestions as to where I might find a table showing u values for roofs walls, windows etc, or perhaps the u values required by building regs over the years?

Thanks,

Phill

See if your library has a set of CIBSE guides or a copy of Faber & Kell. Or give your local planning office a call.
