Frequently Asked Questions

Typically, no. Most glass blocks are designed to be translucent (diffusing light) or patterned, not transparent. They obscure shapes and details, providing privacy.
Common applications include bathroom and shower walls, interior partitions in offices or homes, basement windows, exterior walls for light wells, and as decorative features in stairwells or lobbies.
Generally, no. Standard glass block assemblies are non-load-bearing infill panels. They are designed to carry their own weight and withstand wind pressure but not to support the structural weight of the building above them. Special engineered systems exist for limited load-bearing purposes.
