What's the difference between double strength and double pane glass?
Double strength is one glass piece that stronger than single strength glass but is not insulated. Double pane is an insulated glass option which uses two pieces of glass sealed with a gasket.
How thick is glass on a Clopay door?
Non-insulated glass options are approximately 1/8" thick. Insulated glass is approximately 1/2" thick. Black or white laminate are approximately 1/4" thick.
Why do I need tempered glass?
When tempered glass breaks it crumbles into pieces instead of shattering into shards with sharp edges. Because these shards are dangerous, any residential door that can have glass in the bottom section (Avante and Modern Steel with contemporary window options) must use tempered glass.
Can you change insert design just by ordering new inserts?
For Classic, Gallery, Bridgeport, and Modern Steel, YES as long as you are changing to an insert for the same glass size. For Canyon Ridge and Coachmen NO because the frames are notched for the window design, so the notches would be incorrect for a different window design. The overlays are applied on top of the frames, so frames cannot be changed in the field.
Can a customer change from non-insulated glass to insulated glass?
For steel doors, YES if their door model allows insulated glass. They will need to order both new glass and new retainers. The glass can also change the door’s springing weight, so new springs may be needed. For wood doors, the wood door team would need to look at the exact door specifications to confirm if this is possible. Avante doors may be able to change, but due to the complex labor needed to change glass, ordering new sections (and springs) would be the better option.
Do we replace glass under warranty because of condensation?
If the condensation is between the two panes on insulated glass, then YES if the issue occurs during the window warranty period. If the condensation is on the front or back of the glass, then NO - this is an environmental condition and is out of our control.
What is U-Value?
U-Value is a measure of the heat transmission through a building part (such as a wall or window) with lower numbers indicating better insulating properties. For example, the R Value of insulated glass is 1.47, while the U value varies depending on the type of door material and if the door is operable or fixed, per the ASHRAE Handbook.
