Annealed Glass
Standard float glass that has been slowly cooled from high temperatures to relieve internal stresses, resulting in a product that can be cut and fabricated but breaks into large sharp shards.
Technical Details
Annealed glass is the basic product of the float glass manufacturing process. After being formed on a tin bath, the glass is slowly cooled in a lehr (annealing oven) to relieve thermal stresses. It can be cut, drilled, and edge-polished after production. However, it does not qualify as safety glazing because it breaks into large, dangerous shards.
Frequently Asked Questions
Can annealed glass be used in railings?
No. Building codes require safety glazing (tempered or laminated) for railing applications. Annealed glass breaks into large dangerous shards and does not meet ANSI Z97.1 or CPSC 16 CFR 1201 standards.
