The Architectural Edge
When building with Glass Blocks there are a number of factors that you will need to consider:
Visual privacy - ranges from low (see-through) to high (view
totally obscured).
Visible light transmission - indicates the percentage of light
that passes through the block; typically ranges from about
30 to over 80 percent.
Color - the vast majority of glass blocks are clear, but
color-tinted blocks are also available.
Core - most blocks are hollow, but there are solid-core
blocks too.
Finish - represents the type of finish on the block's surface,
such as smooth, fluted, wavy pattern and grid pattern. The
finish can also incorporate etching, sand-blasting, frosting
and painted designs.
