I am looking to insulate the ceiling of the cellar in my victorian terrace, which is also the floor of the living room. It consists of a wooden floor, joists 400mm apart, about 150mm deep.

I was interested in the Eco-Wool offer at B&Q. Would this be a suitable insualtor bearing in mind the need for airflow etc?

Also, what would be the best method of installing the insulation? I was thinking of holding it up with chicken wire or similar, what do people reckon would be the best?

Any help will be very gratefully received, as my feet are getting colder and colder!

As a much cheaper alternative to chicken wire, I used galvanised steel wire. The way I did it was to put a screw into the side(near the bottom) at the end of the left hand joist. Put a loop in the end of the wire and hook it on, then make a loop 600mm down the wire, put a screw through the loop, screw into the right hand joist, just so the tension pulls the wire straight. Just carry on, my joists were a bit closer then yours. You get a criss-cross of wire that holds the fibre up. Worked well for me.

150 uncompressed -- the air entrapped does the work
