About the same as here - just put in 270mm of insulation in the new
extension roofspace so it'll be nice and cosy all winter!

I've just finished fitting the recommended 270 mm thickness of insulation in
my loft, plus I have 170 mm of insulation under the floors (a summer long
arduous job), and had cavity-wall insulation done last month, plus with the
permissive-E double glazing throughout I am now astonished at how warm the
house is. The thermostat is set to switch on the heating if the temperature
in the hall (coldest part of the house) goes below 22C, so far this autumn
the lowest temperature in the house has been 23C so the heating has yet to
come on.

In the evening the lounge easily heats up 26C due to the warmth given off by
the TV and ourselves. If it has been a sunny day then we have to open quite
a few windows because it does get too hot, even at this time of year. I have
to sleep with the window open in the bedroom because it gets too hot in the
room as the night progresses.

Great stuff Nick and well done!

Be careful you don't make your house too stuffy though as that can be unhealthy.
We sleep with the bedroom window open all year, even in snow. We shut it when
the wind is strong though as the inside doors rattle and keep us awake.
Bedroom temperature is usually circa 10C in winter and around 15C in summer
which is just right for a good night's sleep. Mind you we have a lot of other
windows open usually, partly because we are a bit over the threshold for a safe
amount of radon gas and so we need to ventilate as much as we can. I presume you
are radon free?

Will.
