epsilonGreedy Posted November 6, 2019 Share Posted November 6, 2019 (edited) The material I am looking for will not be incorporated into the final structure of my house. The insulation performance of the material is not relevant, the criteria are light and bulky. I intend to make a linear sausage with a diameter of 400mm and will need at least 100 linear meters of this sausage. Someone has suggested straw bales, I would consider bubble wrap or packing beads though in the case of beads if the wrapper fails during a winter storm the result would be an eco disaster for the village downwind of my plot. Loft insulation works out at £15 m3 and I would need = 13 m3 I think for my 100m long sausage. Edited November 6, 2019 by epsilonGreedy Link to comment Share on other sites More sharing options...
PeterW Posted November 6, 2019 Share Posted November 6, 2019 Is this to wrap the bottom of the static van ..?? bales are best - tarps as a last resort to wrap them as the “flutter” if you’re not careful. Link to comment Share on other sites More sharing options...

No the intention is to keep frost off my footing walls. The B&B floor is in and the outer wall blocks are a block plus a bit lower. Outside of the outer foot wall is a muddy trench about a boot wide. A strong cavity fill comes to 20mm below the outer blocks. The blocks are 19Kg heavies so pretty weather resistant but my building inspector has vaguely mentioned his concern about a full winter of exposure. Straw bales were his suggestion but I don't want to create a high class winter residence for local rodents. Link to comment Share on other sites More sharing options...
Jeremy Harris Posted November 6, 2019 Share Posted November 6, 2019 The only caution I'd raise with using bales would be rodents. Rats and mice really love straw; within hours of stacking a barn the little buggers would start moving in en masse. Link to comment Share on other sites More sharing options...
Mr Punter Posted November 6, 2019 Share Posted November 6, 2019 Hessian sacking? http://www.tarpaflex.co.uk/acatalog/Hessian-Roll-137cm-x-46m-HESS.html Link to comment Share on other sites More sharing options...
Oz07 Posted November 6, 2019 Share Posted November 6, 2019 Are they 7n or upto the correct density for below dpc? Sounds like it at 19kg. I've never heard of this problem is he off his head?! Link to comment Share on other sites More sharing options...
Oz07 Posted November 6, 2019 Share Posted November 6, 2019 I still can't believe what I'm reading. Do you see blocks covered up with insulation in a builders merchant Link to comment Share on other sites More sharing options...
ProDave Posted November 6, 2019 Share Posted November 6, 2019 I can point you to a couple of new builds up here that have been built up to slab level (no doubt to "start" and lock in the PP) and then been left like that for several years and a few Highland winters, with no ill effects.

Onoff Posted November 6, 2019 Share Posted November 6, 2019 As a "temporary" measure I weighted a bit of of dpm down on my flat roof. 4 years later these 9" blocks had disintegrated and I was shovelling them off. Link to comment Share on other sites More sharing options...

Oz07 Posted November 6, 2019 Share Posted November 6, 2019 Celcons are supposed to be good at freeze thaw but anyway I'd be worried about op building inspector. Do you think it's like their equivalent of the "long weight" or left handed screwdriver. They get back to the office and say get on this tony guess what I've got this geezer doing on one of my rounds 2 Link to comment Share on other sites More sharing options...
Ferdinand Posted November 7, 2019 Share Posted November 7, 2019 Whilst I am also with the sceptics, gardeners protecting plants use far less bulky type insulation. The glass lids of cold frames, for example. Farmers use stuff that is like strong clingfilm over seed trenches. What about bubblewrap if you do do it ... or indeed Hessian sacking or just membrane?

JFDIY Posted November 7, 2019 Share Posted November 7, 2019 Cover the brick faces with DPM then bank soil around it, got to be cheapest way I'd think, assuming you can dig enough from the surrounding area without causing a mess. Link to comment Share on other sites More sharing options...
MikeGrahamT21 Posted November 7, 2019 Share Posted November 7, 2019 I’d say just some plastic sheeting to stop the water getting in will be the best thing, it’s the combo of wet and freeze thaw which has potential to damage them Link to comment Share on other sites More sharing options...
