hi there. We have bought an old Schoolhouse from the 1890's that was
converted around 1982 into a home. The Lounge has a mezanine level,
meaning that its double height for much of it and there is a raised
floor are that is a good few feet heigher than the ground outside. We
bought the house just before the summer and when it was windy the
lounge became incredibly cold with cold air coming in along all the
skirting and up through any gaps in the flooring. I thought it might
be a good idea to insulate, but I'm not sure where to start. I was
wondering whether to put some form of insulation underneath the
floorboard or whether to fill the space with some kind of insulation.
Would appreciate any comments as I'm planning on doing this work soon
before it starts getting cold again and my wife threatens to move out!!

Thanks in advance if anyone has any suggestions

Ade
