Window Glazing — Evacuated Glass

Fans of the Curiosity Bin (LINK HERE) might be intrigued by my latest adventure – an
opportunity to examine a crate of an early (Think Generation 1.0) example of
evacuated glass.

A form of insulated glass, evacuated glass consists of two layers of glass molded
together with an air space separating them from each other. Imagine a glass bottle
flattened into a window pane.

Unlike the Thermopane style insulated glass there is no spacer bar and each pane
is completely sealed and remarkably thin. These examples made some thirty odd
years ago were thicker than laminated glass but thinner than the current insulated
panes common to the vinyl insulated window industry.

It is difficult for photographs to do justice to this remarkable cache from the
past, but I tried.

I have no idea who made them or the R value of one pane.

Here are some educational links I found on line:
