We’ve just moved into a house which has a very old, uninsulated loft conversion accessible from the first floor by a stairwell.
With fuel prices being what they are we’re keen to get some insulation in place, but aren’t sure what to do for the best. We know the ideal is to get the now-dilapidated conversion refreshed and to have insulation boards etc put in at the same time, but we won’t have the money for that for a few years.
What should we do in the meantime? Is it worth laying rolls of insulation between the rafters in the loft and thereby preventing heat loss through the ceilings of the first floor rooms? (The rafters were reinforced when the loft conversion was done, so they're nice and deep). But what about the big gapping stairwell which will funnel heat out of the doors and up to the roof anyway. Is it worth the bother? Can anyone think of any other options?
Any thoughts (on cheapish) solutions very welcome. (Incidentally, the house already has cavity wall insulation).
