it depends on the quality of construction of the existing house.
You may be better off spending similar figures increasing the insulation standard of the existing dwelling. ie increased attic insulation, draugh stripping, insulate the attic access hatch, etc...
please tell me why not double insulation?
Hi Sydthebeat,
I'm trying to eliminate draughts in my windows..they're tilt and turn uPVC and basically they're rubbish, you can hear the wind whistling in through them! (if I won the lotto tomorrow i'd replace them straight away)....they've been adjusted and tightened on numerous occasions, even had a guy from the manufacturer here for 2 days but no major improvements....I've used EPDM self adhesive srtips on some of them but to no avail, can you recommend any product or come across any suppliers of such products that can help me?
- Top up the bead insulation previously blown into the cavity as an inspection of this show many peaks and troughs along the wall.
I didn't go for it because of the cost. The house already has a heating/hotwater system so the solar would have to be installed alongside with a new large storage tank and connections to existing system. Even at 4 -5000 euro you are still looking at 10 years hot water costs up front and it wont supply all your hot water.
