Hi all, I'm doing a garage conversion to domestic use. I'm putting in a suspended timber floor, so joists, and then a cavity underneath. They'll be thick PIR insulation between the joists, with the cavity under that. I'm having to rework pipework as currently the existing pipework is in the way...

Over the last few months I've been exploring under floor heating as a posiibility for my ground floor. The house was built in 1884 and has a basement, I mention this becauase even with insulation and carpet, the floor is always cool and if I'm going to lay a wood floor it will be worse. As I...

Morning all, I'm refurbing a ~100yr old house and currently doing the kitchen. It sits on a ~250mm (9'') concrete slab and gets a bit nippy in there so I want to insulate it.

I'm looking to insulate under a couple of rooms before I get the floors sanded. My rough plan was to use something like Kingspan insulation boards, by jamming sections between the joists (or supporting with nails or battons). This seems like an easier solution than standard loft insulation...

I am insulating the ground floor of our Victorian house, have the floor up now and cleared rubble etc below to leave a nice space for ventilation below the floor joists. My question is should I cover the ground soil with anything like a layer of plastic or should I just rely on the ventilation...

I am intending to take advantage of the new government grant to replace my flimsy insulation, the problem I have is I have floored the loft out and use it as a storage place. I have no problem in taking it up but the new insulation required I believe will come above the rafters. Is there a any...

We are having a loft conversion. Both the building control plans and our quote stated we wanted rockwool 100mm under the new floor. Instead our builder has just reused our old loft insulation (very old and patchy) and added a tiny amount of Knauf Loft 44 in places. Floor is now down and walls...
