Hi,
Have got a suspended timer floor (chipboard) in our small 1980s bungalow, the underside is easily accessible due to the large void at one end.
Wondered how worth while insulating under it would be?
Our gas heating bill is around £500 a year, so would the cost of the insulation realistically be recovered this century ?
Assume Kingspan or polystyrene etc are the materials of choice, but should it be pushed up against the chipboard floor or an air gap left.
Also does a vapour barrier need to be fitted and if so on which side of the insulation ?
thanks
