R-33/inch insulation

I came across an ad for next generation kingspan optim-r insulation.

I attached the brochure here:

I’m obviously deeply skeptical, but, thought the community here would be interested.

Obviously if this material really is this thermally resistant it’s a game changer.

Don't think evacuated foam is a new concept

I am certain the price is not game changing

The panels are vacuum sealed and can't have any penetrations. That is how they are getting such High R values. Great for a flat roof assembly but limited use in a wall assembly. The Kool Therm K12 Framing board is R16.7 for 2" thick that KingSpan makes and is priced reasonably in comparison to PolyIso and XPS IMO.

Looks like about US$ 67 per 4x8' sheet. Better than Thermax ($76 for R13).

I paid around $55 a sheet but had a larger order placed, 2 houses. For the exterior of my house it was around $5,500 for the material.
