Ah I see, this would count as a "new element" rather than an upgrade? That's true for the film like products like YBS, but Actis Hybris essentially has the air gap built in, making for much more reliable thermal performance for a given thickness. That said, PIR does look a bit more competitive...

Thanks! As far as I can tell, the changes to rennovations only bring all roof elements in line at a U value of 0.16, which is what I was aiming for anyway. Most bog standard loft insulation roll does have a thermal conductivity around 0.044W/mK, which I assume is what you're referring to as...

You're right it is still quite high, but we're (sort of) limited by the height of the window in the main bedroom, which goes up to 2.57m from the floor or therabouts. I know some people do lower below a window and frame it in but I'd like to avoid it if possible. Also the further it's lowered...
