Am insulating loft (as cold loft), ripping out the old tissue-thin insulation first as it is full of mouse crap and rubbish. Am having problems finding suitable (and cheap) first-level insulation to go between the ceiling joists before rolling thicker stuff over the top. Two problems:
- non-standard size at mostly 41 cm gaps (width of gap, not joist centres) with a few 33 cm at the middle.
- depth is not suited to the current standard sizes - they're only 50 mm deep, and I can't find loft roll (e.g. Knauf) at this thickness.
Can't afford the expensive loft boards that I could cut to fit. And even the semi-rigid rafter roll mineral stuff seems to be a factor of 10 more expensive.
Does anyone have any suggestions? Looking for a solution I can buy in person in the north-east or buy online and have home-delivered. Thanks
