Insulating downstairs ceilings?

[sergeantash]

I'm working on my 1927 house, removing floorboards upstairs whilst carrying out upgrades to the plumbing etc - one opportunity I hadn't considered is using the opportunity to insulate under the floorboards (downstairs ceilings) whilst the boards are removed.

So, I'm wondering...

- Is this of benefit, does it make a substantial difference?
- Can I use same sort of insulation as in a loft? B&Q flexible material stuff?
- Is it ok to cover/wrap around central heating pipes and electric cables?
- Can I literally stuff the stuff in to fill the voids or should I just layer single sheets?

Appreciate your help!

We did this in the floor of our bathroom because Mrs RR was worried about people down in the kitchen hearing her having a tinkle. The bathroom used to be quite warm because there's an Aga in the kitchen but the insulation has made it appreciably cooler so I wouldn't do it again.

Interesting, so provided the upstairs rooms are sufficiently heated its quite a good thing to do - the fact that your bathroom was cooler after proves that the insulation is effective I guess this also proves that the heat is retained downstairs for longer which is one of the goals, my house is always very warm upstairs, but cold downstairs.

If that's what you want to achieve, why not?

Wickes are selling 4 rolls of 170mm glass wool for £29.97 at the moment, 8.1m2 each. This is half the price of B&Q's current offer.
