Eyren Posted July 26, 2006 Share Posted July 26, 2006 We were quoted a horrendous sum for a high-tech insulation job for our conservatory (over 1500 pounds ) - OH and I "fitted" sheets of extra-wide aluminium foil, as sold for turkey-roasting, on the inside for a little over a fiver Not quite as effective or u"Ooops, word censored!"trusive as the fancy stuff, but the temperature is noticeably lower in summer. Probably not suitable for dormer windows, though... Quote Link to comment Share on other sites More sharing options...
