Hi - I am new to posting on the forum but have used it for a long time- great resource! I plan to lay engineered wooden floor, and wanted to know if a good underlay can give the same heat performance as putting rock wool insulation under the floor? It is a joisted suspended floor. The aim...

I am planning to run SpeedFit pipe in the insulation under the floor screed. I will be running it in the SpeedFit conduit. Should I clip it in place or leave it running in a channel in the insulation?

hi. does anyone have any ideas on insulating the cavity between the first floor ceiling and the second floor without having to take the ceiling off or taking the floor boards up. I am thinking about pumping some if that wooly insulation that is normally pumped into cavity walls. Does anybody...

For thermal and noise benefit, considering insulting under floors in single storey 1930s property, brick cavity wall (filled). Important factors: - not sufficient crawl space to work underneath, so need to do from above. - timber T&G floorboards. - soil solum. Original plan was simple: 1. Loft...

I'm replacing my kitchen floor and altering some wiring so while I'm under the floor I was considering insulating the heating pipes to reduce heat loss. Only using the cheap grey foam that's about 99p for a metre. Also offers frost protection. Then it dawned on me about the cold water main...

Pleease can someone help. I live in the central Highlands of Scotland in a timber style cottage we recently had the roof insulated but find we loose a great deal of heat and get a lot of draughts from the floor which is the suspended type, however there is not enough room under the floor for...

Hi My daughters 110 year old house has a void under the floor boards, I'm thinking of insulating the under the floor boards with kingspan 25mm insulation boards. Is this a good idea or what? Cheers

When building floors, why don't more people lay a concrete slab, then, say, 100mm of PIR insulation, then a chipboard floor? It seems to be that it would result in a warmer feeling room - less thermal mass anyway? Thanks Gary

Hi, I am at a complete loss as to what to do best here. We are having roof put on conservatory and would like under floor heating fitted. The problem is the new flooring is to be laid throughout most of downstairs including Kitchen into Conservatory. I think the best way would be to put...

In the process of rewiring and repiping the house, so ceiling between ground and first floor has been removed. Would you insulate between joists or is it pointless as both floors are heated. There's acoustic insulation all over under the flooring upstairs, so no noise problems. Thanks for your...

Hi Everyone Hope I have posted in the right forum We moved into a 1920's house a year ago and over the winter have been aware of how much draught comes up into the house from a fairly large crawl space under the house I'd like to insulate down there-I have searched and seen suggestions...

I was wondering how you go about insulating floors in Victorian houses. Under the floor, there is a dwarf wall, which sits on earth. On top of the wall sit untreated rafters, on top of which sits sheets of compressed wood bits. I know these type of floors must have air flow via the air bricks to...

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...

Working through the house re-doing a few rooms, and the lounge and hallway are looming up on the list. We want to lay a timber floor, probably engineered rather than solid, but I want to lay insulation under the floor as the existing floors are not insulated. Our ground floor is 20mm...

hi, Going to be pulling up most of the upstairs floors in a 2 storey house to get a rewrire done and install underfloor heating throughout. While floor is up and before rewiring is done, considering installing insulation under the floor to minimise heat from downstairs rising upstairs...

I'm thinking of doing this too, however, is it a fire hazrd having loft insulation under my 1920's floorboards? there are small gaps between some of the floor boards where the connecting sections have been damaged. Just wondering if it's a fire risk if there was some ash to fall down this gap?

Hi We want to sand down and treat our existing floorboards in our sitting room but there is no insulation underneath the floor. I'm concerned that it will get pretty cold underfoot. We don't want to lift the existing floorboards but do have access underneath them at some points - is there a...

Hi all - loving the new forum look. Great on the mobile (not been on here in a while). I'm going to be moving into a new house next month and have an insulation question. It is a bungalow but has a large (and very dry) basement. The ceiling of the basement, which is the floor of the main house...

I live in a 1960s/ 70s detached house by the coast, I've recently increased the loft insulation to about 350mm the house can be drafty at times with air coming from behind light switches and under bedroom doors, can I fill the void under the bedroom floors with something like glass mineral wool...

Hi all, I recently installed PIR insulation under the floorboards in my lounge. Hopefully some of the details here might help someone, given there aren't many tradesmen who offer this service (given the time involved, I can see why!). The house is 1930's with a suspended floor and it's about...
