do you have this in US http://www.durisoluk.com/icf-technical-advice/polystyrene-icf-woodcrete-icf/ no need for bracing and you can fill 8ft at one lift with no support because it is wider and very stable

are they a lot more more money in US than poly forms--
not seen these mentioned before here
looks a good system to me with all insulation on outside of concrete so that can become a real thermal mass.
downsides please if you have experience of them

The insulation value of the wood blocks is low relative to foam.
The blocks are heavier than foam and shipping costs are higher.
The benefits of having the concrete all inside the insulation envelop are overblown in my opinion. The mass benefit of having the concrete all inside the insulation envelope is only fully realized if you allow your interior temperature, and hence the concrete, to swing several degrees throughout the day. Most people in the US don't do this; they set a temperature at the thermostat and let it maintain a near constant (+/-1 deg F) interior temperature, especially if they have an electric heat pump for HVAC; otherwise your risk of energizing the electric heat strips outweighs any savings benefits of allowing the temperature to swing up and down (not to mention the comfort aspects).

Hi,
ok thats your opinion and accepted
but physics says that concrete will not gain or loose heat at a quick rate -so the temperature swing will be much slower,virtually nothing once target temp is reached with high thermal mass inside insulation.
the stated insulation value of blocks with insulation included is 0.15 --so it is better than the poly foam .
lets assume they are exaggerating like most suppliers with vested interest --
It is so easy to attach extra thin of your chosen insulation on exterior-then finish as per your choice - to give 100% wrap and no thermal bridging ad get down to passiv or better spec
I can understand why some choose SIPS ,where getting concrete to job is hard and expensive
My opinion --from what i have read so far -- much easier to attach things too as you can screw directly to it any part you like ,can even hang heavy things on it and in uk cost of them is similar to poly foam type blocks ,but no racking needed and If house is only one level can be filled in one lift .
hoping someone has an even better reason for me not to think woodcrete is not a good alternative for poly formers
I have very open mind on the subject .
delivery costs are free in Uk on both systems

I think Durisol are great blocks. They breathe and if you use lime plaster interior and real cement stucco exterior then you will have a very comfortable home. I like the ability to attach anywhere also. Fire resistant and no fumes if there is a fire. They are used quite a bit in the UK and have a great track record so no reason not to use them I'd say.

If you get a quote please reply with info. I believe it is more expensive than ICF when including the delivery.

I think it would be great in a crawlspace or garage because you can leave the interior unfinished.

no problem
but i do live in scotland not US
where are you based?

after much technical searching -- woodcrete is not the way
and now ifound a concrete pumper that will do it reasonable priced £600 perday 8hrs on site it looks like ICF is back at top of the list
two days of pumping will kill the job

Other than the higher price, the problem with woodcrete\nexcem\durisol IMO is the lack of air- and water-tightness that foam and a solid concrete wall provides. That means you have to parge the exterior with a cement mix plus below grade you still need a bituminous or dimple membrane layer. Door and innie window jambs seem problematic; everything just seems like it has to be perfect or else you will have water problems - still better than all wood construction however. But I do think this is an awesome system for a breathable mediterranean or adobe house where you already require stucco and plaster. I love the feeling of those solid walls

If I could have an ICF with interior woodcrete (or aerated concrete) and exterior foam and with small ties to hold it together (so I get a solid concrete wall), that would be almost perfect - get all of the exterior benefits plus on the interior I get thermal mass and the ability to leave garages and crawlspaces unfinished (no drywall for fire code).

Hi the price for durisol 365 blocks which have in built PIR insulation comes out at 8gbp per sqm --you need 8 to blocks to make 1 sqm --a truck load,uk truck smaller than US ones which equates to 1440 blocks wil cost 900gbp for delivery to site 350miles
so thats 8.2bgp per sqm on site-- definately cheaper than poly ICF blocks +-no bracing required
bracing was quoted to me by becoowall at 180bgp per week +500gbp to return them at end of job --delivery to job was built into block pricing
so durisol is coming back into favour .
as far as the breathable bit --it says in the manual that walls should have thin parge coat if not being rendered on outside

Scott.....can you put that in US dollars?

I didn,t convert cos exchange rate is variable -but todays rate says 1.27dollars to the pound
I also see Imade a mistake
$10.50 per block --8 blocks to sqm
wish it was $10.50 per sqm LOL
so price sqm=$84.00 delivered to site
but i can,t say its same price in us

I was quoted $19.70 USD per R22 14" block (for a big order). Includes delivery to my area (Minnesota). Each block is 12" high and 24" long. So ~$10 sq\ft wall just for block; so about double the cost of poly ICF.

yes that is interesting - so yes more expensive in US,
more study required before final choice i think.
I got quote today for integra spec at $50 per sq m or $5.5 sqft and that works out at about 1/2 price of durisol .
my pricing was for the largest durisol block 365 with inbuilt insulation or 14" in your units-same as you quote.
maybe i should be shipping ICF to states .LOL

Hi Scottishjohn I am also in Scotland (Central) and looking into the possibility of using ICF. Have you gone any further with your design. Have you been to see any houses that have gone done this route. I would love to visit a site before, during or just after a pour.

I have looked at every type available in the world
I am stuck in planning phase at this time,
but my current favorites is probably VELOX or ISODOM 2000
https://econekt.co.uk/izodom/ is scottish agent
but until i have design to get a quote on -i am stuck to get accurate pricing
durisol is still on the list --but until plan cannot get quote either.
If you got plans --send them to your chosen system supplier for quote -and get quote for bracing system --thats a must ,except possibly for durisol or velox.
go onto to build hub .org and search there plenty of people using all dif types
