Hi All,

I am looking to get some insulation in my loft however the loft is fully
boarded with nailed-down floorboards. I don't particularly want to go
through the hassle of lifting them and then relaying them after and also a
builder we got to quote reckoned that this wouldn't be a good way to go as
the joists are quite shallow and banging around would probably disturb the
ceilings. He also reckoned that as the current guidelines are for a 10 inch
insulation layer we wouldn't be able to relay the boards anyway without
compressing the insulation and compromising it. He advised us to either a)
lay the insulation on top of the boards (but this would make the loft space
unusable) or b) lay some other insulting material which can cope with some
loft-boarding on top of it.

Does anyone out there know of these other types of insulation (he was a bit
vague and I was a bit pushed for time by this point so didn't quiz him to
vigorously) and what their relative merits/pitfalls are? Are there any other
solutions bearing in mind we would like to use the loft space for storage
etc?

Cheers

==================================
You might consider using polystyrene beads (about 6mm) which can be poured
into cavities. You would need to drill suitable access holes but otherwise
no other disturbance. Obviously, the depth would be limited by the
overlaid flooring but it would be better than nothing.

You would also need to avoid any wiring which can be degraded by
polystyrene - plenty of dire warnings here from time to time.
