Smaller build with Isotex

[RichyO]

Hi there, new to this site and very glad I’ve found it too! I’ve been considering a durisol build for a smallish garage build (40sqm approx wall area, 3xwalls with 2 doors). Attracted by simplicity of the block build approach. However, looks like durisol may not now be an option due to administration so checked out Isotex and wondered why I hadn’t spotted that before - looks good. However, turns out they have minimum order of 140sqm due to transportation costs.

 

Has anyone managed to get around this by teaming up with another build!? Any other advice given the current durisol situation? I have contacted them but it’s gone quiet unfortunately..

 

Many thanks.

Double up the wall thickness and get a decent U Value.

Durisol going will the the ICF industry a favour.

 

But as it is just a garage, why not block and render.

Hello,

I am building a passive house in France. Initially i was going to use Durisol, then I found Isotex. The reason I chose a heat treated wood based ICF was because there are Termites on the land and although they don't eat Polystyrene they can burrow into it.

As far as I have been able to find out, the differences between the two blocks are as follows:-

1) Isotex is a denser block i.e. more wood chips are pressed to form it than is used to make Durisol.

2) The concrete infill on Isotex covers the joints so helping with airtightness.

3) Durisol is sold by the pallet so you may have to buy more than you actually need. You send your plans to Isotex and they work out what you need.

 

I have contacted Isotex in France and Italy. they are a bit snooty and like talk to my architect rather than me.
