Hullo. Can anyone help me to work out which way to insulate under the floor in my living room. We have floorboards and a large crawl space underneath.
DIY books and colleagues have suggested blanket insulation and netting. Have started and actually stapling the insulation material to the joists seems to work ok - netting just to hold material in place right?
What depth insulation should be used - just trying 100mm - just to stop draughts to living space from air vents underneath.
However, can't find (after searching for some time) info. on whether insulation should be butted right up against the floorboards from underneath or suspended to leave a small space between the floorboards and the bottom of the joists - not hanging below joists but so still a space between floor boards and the insulation - to trap warm air - or will this cause condensation / stale air / problems.
Thanks
