Can I insulate under my floorboards. Will there be a problem with condensation, what's best to use. thanks
There's a cellar underneath & an amount of pipework & electric cable. Have been looking at extruded polythene board, my house is freezing & no-one will come visit me, not even my kids!! Been bit bothered about the condensation aspect. If I put this board stuff underneath the boards will it prevent the airbricks doing there job. Apologies if you looked at my earlier question, Missed the 110 characters bit, new here. Doug

DO NOT use the extruded polythene board under your floorboards. Go to a home improvement center and explain the 'heat leakage' problem to someone there ... there are several GOOD things you can use, including your basic 'ceiling insulation' under those floor boards.
