Describe block glass and how it is made.
What will be an ideal response?
Glass blocks are made by fusing two halves of pressed glass together, creating a space with a partial vacuum. This produces an insulating value equal to a 12 in. (305 mm) thick concrete wall (U-value 0.51, R-value 1.96). Glass blocks are very strong and provide excellent security.
