Rick coughed up some electrons that declared:

Hi,

Can any of the subscribers recommend me a good loft insulation for a
semi-detached two story family house please.

Either PIR board (eg celotex - if you have enough ventilation that it
doesn't cause condensation problems. Expensive but twice as efficient as
rockwool typically, thickness for thickness.

Or sheepswool - the green and un-foul alternative to rockwool. Similar
u-values, and last time I checked, similar prices. Not sold in the sheds
but easy to find local distributors via google.

At the moment I have some old rather scraggy fibreglass material I
need to replace.

Been looking at this, any advice would be much appreciated ???

That looks like "fad" to me. It may reflect radiant heat but what about
conduction? Doubt it will do any harm, but I'd combine it with a layer of
wool too.

Cheers
