Heat Strengthened Glass
About
JTG’s Heat Strengthened Glass is approximately two times the strength of annealed glass and does not exhibit the small particle break pattern of tempered glass. Spontaneous breakage due to nickle-sulfide crystals does not occur with heat strengthened glass. This product is recommended when excellent resistance to extreme solar stress and cyclic wind loads is required
Available thicknesses glass
1/8″, 5/32″, 3/16″ and 1/4″
