I was just chucked in level to the underside of the boards. No ventilation of any kind - and the boards were turned, had a saw cut run down each side and relaid as T&G flooring (the tounge was a glued in fillet).

No vapour barrier of any kind other than the boards were pretty well fitted (and mother wanted them polished and exposed anyway) and did have endless coats of wax.

The house is still in the family - my kid brother and his family lives there now - and there is absolutely no evidence of any rot or damp under that floor.

Just anecdotal evidence I guess - but seems to back up Vikings exerience

So I'm trying to find a cheaper LWA and maybe fill some of the first layer with something else, then a LWA up to the floor joists and then wool between the floor joist laid on top of the LWA to get the best u value and to also stop the mice (of which I seem to have hundreds of) from eating any other insulation, which so far they have eaten all of the insulation from the heating pipes.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2850&Focus=201198#Comment_201198 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2850&Focus=201198#Comment_201198 Fri, 02 May 2014 10:36:36 +0100 barney
It was probably around 10- 12mm beads, they came from a nearby concrete block works that used to make LECA blocks amongst other things.

I suspect my old man did a deal with the guy running it (they had been old army buddies) and I can remember it turning up in a tipper from the supplier - I may even have filled the odd barrow and had a ride round on the journey from road to lounge.

I can't imagine for a minute that it was expensive (pro rata).

It doesn't have a particularly good insulation value - you'll need roughly 3 times the thickness to match EPS.

Finding a supplier who deals in bulk is the key - buying it in jumbo bags by the m3 is fearsomely expensive - particularly from so called specialist suppliers - you want the people who are supplying by the many tipper load to civil engineering projects and can blow it straight in or dump it outside in 20m3 plus loads.

Try looking for Plasmor or Alfa bulk suppliers

Good luck anyway

Think I might have to sack this idea as it's going cost thousands.

I have no advise for you Victorianeco, I'm new to this myself. I really wanted to use LWA because my heating pipes run under the floor and bloody mice keep eating all the insulation. So once I insulate and put new flooring down my pipes will be beyond the thermal barrier and if fecking mice eat the insulation again I could end up with burst pipes. The prices for LWA are just so high and I could insulate using BDPM and wool (or something) for 1/3 of what the LWA is coming in at.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2850&Focus=201383#Comment_201383 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2850&Focus=201383#Comment_201383 Tue, 06 May 2014 12:16:51 +0100 Victorianeco https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2850&Focus=201384#Comment_201384 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2850&Focus=201384#Comment_201384 Tue, 06 May 2014 13:02:56 +0100 ClareB1 ]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2850&Focus=201397#Comment_201397 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2850&Focus=201397#Comment_201397 Tue, 06 May 2014 17:21:17 +0100 jamesingram Same with lime product , wood fibre insulation . all shipped from France, Germany etc.

So, for my project, some context might help. The first thing is I have a very small flat I'm doing this in - under 50sqm. I decided the best way to lower my 'footprint' would be to convert my 3-bed terrace into 2 flats, so did the upstairs with dabbed insulated plaster board, created an internal bathroom, and put a kitchen in the old bathroom. This is now let out. The ground floor will be my new, smaller, home.

I decided (due to rotten joists in many places thanks to previous owners raising ground levels, plus poor floorboards, plus limited wall space due to it being a small, open plan flat), to go for solid floors & underfloor heating. Because it is what I know the most, and have worked with the most, I always knew I'd be doing a hempcrete slab. Initially I was planning on silicone-coated LECA, but I uncovered enough concerns about the silicone coating not being guaranteed to have coated each clay ball fully etc. PLUS the fact I'd need 200mm of it rather than 170mm of foam glass, which would need digging out, that I decided to go with the foam glass. It's costing £135 per m3, and I will be using 9m3.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2850&Focus=201424#Comment_201424 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2850&Focus=201424#Comment_201424 Wed, 07 May 2014 00:00:32 +0100 slowbuilding
So, I dug out my floors to 380mm, and will have 35mm of gravel first, just to level things firmly, then 170mm foam glass, then 100mm hempcrete slab (this gives me better than 0.25 I need for Building Regs). On top of the hemp slab I'll put ufh pipes, and then a 50mm lime mortar / screed in one, with terracotta tiles on top.]]>
