[Iceverge]

Are you planning on stick building the frame? 

 

Have you considered blown insulation AKA cellulose. 

 

There's lots going for it.

No it will be open panels. Preferred the rockwool approach as we can do that ourselves

Getting the cellulose pumped isn’t cheap either. It’s good, but rockwool + DIY will be more cost effective.

avoid a cold-ventilated sub floor like the plague,

And 450mm isn't enough to justify beam and block.

The very clear difference is that below a slab you can have ground, (which insulates) or insulation, whereas below beams you have a draught.

Experience speaks. Agree, a ground bearing slab will benefit the overall u value calcs.

What's the UK price now?  It's 4-5 years since I priced it here at €150/m3. 

 

Fitting mineral wool isn't particularly nice as jobs but it's very doable. Has anyone done blown mineral wool?
