I'm trying to work out the losses in my new (1970) bungalow.

Many thanks to everyone who helped with this or the previous question
about underfloor heating.

My spreadsheet (not guaranteed correct, or even sensible) is on my
website, if anyone is interested:

There are three scenarios:

1) the original almost uninsulated house (July 2005)
2) what I hope to have by mid January after loft insulation to 250mm
and low-e 28mm double glazing (January 2006)
3) and my plan for the next phase with Cavity Wall insulation and some
other improvements (Next Phase)

Of course, the key thing to realise is that U-values have to be added
up as reciprocals..... Thanks again.
