What is the Thickness of Glass Used in Most Residential Replacement Windows?
The vast majority of residential windows use Single Strength glass which is 3/32” thick. For larger windows, Double Strength, or 1/8” thick glass may be required. For extremely large residential window it may be necessary to use 5/32” or 3/16” thick glass to assure adequate wind-load resistance. A few manufacturers use Double Strength glass as a standard in lieu of Single Strength because of it’s greater resistance to breakage and better noise reduction characteristics.
