I'm just in the process of refurbishing our main bedroom and its ensuite........I'm in the process of taking the opportunity of lifting the wooden floors up and putting lots of insulation material between the joists, I'll probably have the chimney bricked up and blocked off...still keeping the ornamental fireplace (we don't use it).
Every room that we refurbish we do exactly the same, up come the floor boards and lots of insulation material between the joists. We note the house warms up quicker when the heating comes on and stays warmer for longer, but most importantly the level of draughts is diminishing....mind you with a house with 24 air bricks, the cavities are well ventilated and the windy cold sea breezes still represent a challenge from time to time, we can hear when the tide turns, down our chimney!
