Lightweight EPS Concrete Panels - R Value Query

G'day All

I wasn't sure where to put this post as there is not an insulation or structural insulating panel (SIP) category.

While on eBay the other day I came across DIY Affordable Homes selling Lightweight Precast Sandwich / Concrete Panels

Lightweight Precast Sandwich Concrete Panels | eBay

When I followed the link to their webpage DIY Affordable Homes I was surprised to read the R value claimed for the panel.

According to the "manufactures tests" a 60mm panel has an R vale of 7.69. This appears very high compared to EPS (polystyrene) which for a 50mm panel has an R value of 1.28 (for VH class).

Is this some new wonder insulation or are the "manufactures tests" much more "generous" than AS 2464?

I would be interested in others opinions or at least let me know what I am missing. :rolleyes:
