Kingspan Optim-R (Vacuum panels)

[gc100]

Due to certain restrictions on my build it looks currently that I have 150mm of PIR insulation in my zinc vaulted roof. Does anyone have any idea how much Optim-R costs and where its worth the extra cost? Also does it retain its uValue over say 10/20 years?

 

Anyone know much about this? 

Thanks!

Kingspan also do this, perfect for a zinc roof, no idea of price though

Last year kingspan told me over the phone £68/m2 for 150mm Quad-Core roofliner, but almost certainly it can be had much cheaper if having via supply and fit from a contractor. This was the case with their prices for RW1000 panels.

Thanks for that but that Kingspan product is 0.08 W/m·K vs 0.02 of their standard PIR so don’t really see the point aside from ease.

 

i just released that I’ll never be able to use the vacuum panels as I need to put screws right through them into the joists with my roof makeup. 
 

thanks anyhow

Zero missing? "OPTIM-R E panels achieve a declared thermal conductivity of 0.009 W/m·K", source.

I was referring to the Quadcore linked above vs ‘standard’ PIR
