The crowd in Cavan are called Interspec, they are based in Ballinagh. I was talking to the owner who seems to know a lot about a lot of things when it comes to houses. He said that no matter what company you go with, with respect to ICF, it is the best build.
....its Integraspec by the way.
And no, not all ICF systems are the same...
- polarwall use extruded polystyrene as opposed to expanded polystyrene (EPS) by other suppliers..... I don't know which is better
- some, but not all systems have furring strips so that you can screw plaseter board onto as opposed to dab & slab
- the thickness of the UPS varies also 50mm's each side upwards. Integraspec are at 63mm's each side.
- euromac have a roofing systems & concrete insitu system. (have not seen that from anyone else)
...apart from the system, you need to watch that the installer is experienced & knows what he is doing. The walls have to be straight.
- also does your builder know how to correctly apply the acrylic renders so that it does not crack in the future. (he will tell you yes... ask to see where they have done this, inspect, have your engineer inspect)
...just a few things to be aware of.
Fortunately for you, as far as I can see, Integraspec looks to be a pretty good system.
Have you got quotes on how much this will cost v's a highly insulated conventional form of construction?

BTW, just be wary of "he owner who seems to know a lot about a lot of things when it comes to houses" ... he's a salesman...... has he told you of any downsides?
Is his system/bulder homebondeed/premier bonded etc etc?
