Scientists develop game-changing ‘glass brick’ that could revolutionize construction: ‘The highest insulating performance’::The team of scientists developed an aerogel glass brick, which is a translucent and thermally insulating material.
I wish the article would have mentioned an R-value or at least something to describe the actual efficiency of its insulating ability.
Any time an article references another, immediately jump ship and read the original.
The glass brick has a measured thermal conductivity of 53 mW/m*K and a compressive strength of nearly 45 MPa.”
“This is the highest insulating performance of any brick found in the technical literature, let alone on the market. Additionally, it comes with the property of light transmission.”
