U values for older houses ?

In a previous thread a discussion formed over the merits of new houses
over old, one obvious advantage being the greater thermal efficiency
of new houses.

The current building regs for the U value of external walls is 0.35.
My 1950's "ventilated brick cavity brick" is apprently 1.9.

Does anybody know what the likely U values would be for older houses
e.g. victorian houses with solid brick/stone walls, cottages with 2
foot thick stone walls etc.

TIA

According to Myson heat loss calculator, a 200mm solid brick wall is
1.8, 18inch solid stone is 2.5.

Thanks both for the info.

Looks like there ain't no such thing as a cosy cottage then !.

Once you get it up to temp :-)

I'm happy with cosiness inside my 18" walls but I always have the heating
on just a bit so that I never have to heat it up from cold.

Check out cob then. 2 ft thick mud, straw and cow dung. Excellent U
values
