INSULATING FLOORS
Discussion
90 year old house, no cavities, recently had loft insulated but i dont feel a great deal of diference.
Downstairs front and rear rooms are wooden floors and i'm thinking off fitting 100mm kingspan between the joists under the floor, do you think the outlay (around £360) is worth the benefits, or should i just forget the idea.

We've done that in a 1880s victorian place and it has made a huge difference.

Old pine floorboards are brittle and we did not want to trash >30% by lifting them all so we did it from underneath - ie cut bits of kingspan to fit and then push up and batten in to place under the floorboards.
How deep is the void under your house?
Ball-acher of a job but well worth the day or so it took 2 of us to do the 5mx5m lounge.
PM me if you want any more hints and tips!

We had a problem with damp in our Victorian Terrace a few years back. Had to take up all the floor boards in the living room / dining room and replace the wall plates and most of the boards.
While we were doing it, we installed new airbricks to the front and back elevations, and installed 50mm of polystryrene between each floor joist. Then put the floor boards back down.
Total result, the dining room and living rooms are much warmer, our heating is turned right down and we can walk around barefoot on the timber floor boards even in winter.

Suggest you look here for your insulation needs, I saved a fortune. Their offers vary day by day so you have to keep your eye on it. I got some 150mm sheets 2.1m2 for £15 each.

Currently doing just that myself but in the loft. I put 50mm Kingspan in the loft on our end wall (semi) with 50x50 battening. The difference was immediately noticeable. Last week I had another delivery of 6 sheets to do under the tiles inbetween the rafters. Each sheet is 2400mm x 1200mm x 100mm like you are proposing. I stuck them in the dining room against my security shutter which goes into the conservatory (its closed during the winter) and when I opened the door yesterday it was like a blast furnace! Thermostatic radiator valve is normally on 4 but with all that insulation in there its now one 1 so it works.

I paid just under £28 per sheet which I thought was good, and that was delivered, the stuff came from ebay. I'm so impressed with it I'm going to do the log cabin down the end of the garden because I think it would be as good as a house. Do wear a mask when you cut it as the dust gets in the back of your throat, but you can cut it with a rip saw and its easy to shape. I cannot comment on how efficient it is compared to other methods but I bought it because the specialist recommended it. If I can feel a difference just with it stacked up against the roller-shutter then it obviously is going to save me something and with gas costing me about £100pm, I am more than happy to try and reduce that.
