Our glass offerings are tempered and meet or exceed known safety requirements and regulations. Standard Clear and Sand Blast are 3/16” thick, but thickness can increase to ¼” or larger depending on glass size and application. Standard 1 ¼” Beveled glass is ¼” thick, but thickness can also increase depending on glass size and application. Acceptable tolerance on 1 ¼” Bevel is 1/8”. All Architectural glass is 5/32” thick, and thickness will not vary. Single tempered glass is standard for all interior applications with the exception of wine cellar doors. Insulated glass is standard for all exterior and wine cellar doors. When ordering a product in which insulated glass is standard, the specific glass type chosen will be insulated over clear glass with the interior side of the door being clear unless otherwise specified. A ¼” black matte spacer is used on a majority of applications, but the size of the spacer can vary depending on window size and application. Standard Clear, Sand Blast, and 1 ¼” Beveled glass are available in all designs ordered in standard sizes. Due to tempering restraints, our Architectural Glass will occasionally have certain limitations depending on design. Please consult the Door Style Limitations section for a detailed list of these limitations.
