Hiya, it's a complicated calculation. But a loose lay insulation such as rockwool (energy intensive to produce) or sheeps wool or woodfibre will have a lower value but is better at reducing voids vs PIR. Difference in building energy use will likely prove negligible for a project this size. That's my 2 pence. Don't mean to derail the thread, which is awesome!

Thanks for the pennies! Want to come and build it for us?

Thank you, wish I’d have had you to grab a chat with a few years ago!
@jonny that’s really kind of you. I must get more bike pictures, was off to work on the trackshark today. Yeah we really couldn’t be happier with it, hoping most of the scaffolding is coming down tomorrow so we can get a proper look at things not hidden away.
Got our solar panels fitted and really couldn’t have squeezed any more out of the roof space! Really happy with how they look with the all black as well. Don’t worry, that ones not cracked, just dusty..
Also, saw this headline in this week’s newspaper! New homes built by the housing association up here have been quoted a year for metering connection.. A really terrible situation for some folk locally but must admit feeling a little smug knowing we don’t have to go through that ordeal

As you know all about sustainable practice, and you're insulating your home, I reckon you're the right person to ask.
I noticed you're using PIR insulation. Do you know anything about the balance of using a more eco friendly option? ie the impact of producing PIR vs how much less energy you'll use to heat the home.
We have the option to insulate a new roof with rockwool etc rather than PIR, can't really work out what the best, least impact route is.
