Good for you, you’re not a waster wih a 1950s $3/bbl oil mentality. The operable, insulated, automatic-on-photocell window shutters available now are just too expensive, the cost/benefit ratio doesn’t work for the average homeowner on his own dime. And yet here is an opportunity for some major insulation manufacturer to develop mass produced units backed by public financial support, to cover vast numbers of energy-robbing window-holes in homes. Plus you can add insulation panels to walls, like thick, new siding; and “quilts” over roofs. Hey, it’s your own money you’re heating the cold night air with, why?
Well, the loft insulation is 6” thick already. I find after the double-glazing I just don’t need the gas central heating on as much or at such a high level.
I have toyed with the idea of cavity wall insulation. I’ve done it before, but I’ve heard bad things since about it restricting air flow. Any comments?
I’m told that “blown” wallpaper is quite a good insulator - considering you have to put the stuff on anyway you might as well.
