OK Guys,

I'm thinking that the whole idea is too much trouble for me to do,
Doing it properly, ripping up the living room floor and insulating between the joists will take me a long time (If you saw my woodwork you would get why) Embarrassed

I thought I would lay insulation on top of the floor but after measuring the tops of the door frames....nope Roll Eyes

So any comments on this underlay? Undecided

Thanks again Smiley

If you only have space for this thickness of underlay it is probably about as good as you can get. I've used it and it is a good surface on which to lay laminate.

Thanks Woody,

I was hoping for a bit of both, I think that noise might be a problem (I never noticed noise before as I had both good carpet and good underlay down)
I've been sitting here every evening listening to footsteps Sad

Incidentally I've gone round the edges with expanding foam (now the skirting is gone) and I don't think there's a draft any more

Sealing that gap will probably make more difference than insulating the floor.

A 5mm thick underlay will make next to no difference to the heat lost through the floor by conduction. However putting a layer of any sheet material down might well stop heat loss via draughts coming through gaps.

I refer to my previous reply... The best insulation in the world needs to be about 50-60mm thick to achieve the level of insulation recommened for floors in the Building regulations. So a 5mm thick fiber board would be at least 12 times worse than the regulations recommend.

Thanks CW and others for all your help

I did understand that to do the best job I should take up the existing floor but to be honest its too much hassel.... Embarrassed

So it will be just the green stuff....I know there's not much U value there but now I'm getting worried about the noise
I'm thinking there might be a few rugs, one or two of them hanging on the walls Wink

I might start knitting one

It has a vapour barrier and is good for noise. It works out at £2 a square meter, which is not too bad for 5mm underlay of this type.
