A couple of years back I posted a question .. didn't get very far,
thought I'd try again.

I have a modern highly insulated 2 storey house, and this time of year
the upstairs get very hot .... and with high values of insulation it
does not cool quickly ... bedrooms are very hot.

One option is install a LOT of thermal mass and draw the curtains by day
and open the windows by night.



We recently had the 9 inch solid walls of our house insulated with 90mm
EPS board and finished with the light weight render. We never really had
any overheating problems prior to this but everyone has noticed the
house is much cooler! Whether 9 inch solid walls are classed as 'a lot'
of thermal mass I don't know but we certainly notice it is cooler than
other houses that have the insulation applied internally or are of a
different construction.
