Which leaves the Holy Grail, discussed on here before - how to
insulate under a suspended timber floor, with no access from
underneath, without removing the floor.

Filling the entire void is not an option, unless you want your joists to rot
away within a few short years.

You can't get access under the floor and you don't want to take the entire
floor up? - then it cannot be insulated, end of story.

You could insulate above the existing floor, with 75mm celotex or similar,
then put a floating floor above that, but then you'd lose about 90mm of room
height (and your internal doors would be 90mm shorter too) plus you'd have
to put new skirtings all the way around

These have been my conclusions, every time I've thought about it :-(

I can only see two ways to make the floor warmer, short of a detested
fitted carpet, with its propensity to collect dust, and stains from
coffee, wine and mouse blood. Or ripping the lot out and replacing
with concrete, which would be stupid and unnecessary ;-)

One is to remove my skirtings, prise up the floorboards, insulate,
tidy up the boards on a table saw, refit, fit new skirtings and
decorate. In three rooms and a hallway.

The other is to continue to collect relatively inexpensive Persian
rugs, and attach Tri-Iso insulation to the backs of them. That way
much of the heat loss would be eliminated.

Hence my reference to the Holy Grail - don't bring me common sense,
bring me solutions ;-)

Surely only one or two long boards removed would provide access to
blow insulation under?
Even if you wanted to remove ALL the boards, sawing through the tongue
on one with insert favourite sawing device here would release them
all (once skirtings off).
