Two winters with no loft insulation is quite enough and I have been
costing the various options, which turn out to be

Wool batts
Conductivity 0.038 W/mK
£11.30 /sqm

Flax rolls
Conductivity 0.037 W/mK
£15.00 /sqm

Isowool rolls (glass fibre)
Conductivity 0.04 W/mK
£1.70 /sqm

Even if VAT needs to be added to the glass fibre option it still looks
loads cheaper than either of the others so I can see why the
eco-products haven't hit the mass market yet. I'd be prepared to pay a
bit more for them, but an order of magnitude more sticks in my gullet

Anyhow whats eco-unfriendly about glass fibre. Its only sand, isn't
it?
