Heat Strengthened Glass Market Professional Survey Report 2019

Heat Strengthened Glass -MARKET ADVISORY SERVICES

Heat-strengthened (HS) glass has been subjected to a specifically controlled heating and cooling cycle, and is generally twice as strong as annealed glass of the same thickness and configuration.

HS glass must achieve a residual surface compressive (RSC) level between 3,500 and 7,500 PSI for thickness up to 6mm, according to ASTM C 1048.

It has a greater resistance to thermal loads than annealed glass and when broken, the fragments are typically larger than those of fully tempered glass and initially may remain in the glazing opening.

Heat-strengthened glass is not a safety glass product as defined by building codes.

It is intended for general glazing, and is usually the choice for commercial applications where additional strength is desired to withstand wind load and thermal stress, but the strength of tempered glass is not necessary or required by building safety codes.
