FAQ

Frequently Asked Questions.

Should you have any glass related questions, please call and we will be happy to assist you.
1What is our Warranty?
Truthfulness is our policy. Each product we offer carries a separate warranty. Once installed (shower doors, thermal units, etc.) we will stand by our installation for a period of one year. The product itself will carry a manufacturers warranty against defect for 1 to 5 years, depending on the product. Any offer of a life-time warranty from another company in the glass industry is merely a sales pitch. Do not be fooled.
2What is the best cleaner for glass and mirrors?
There are many good brands on the market. We sell an aerosol can that produces a foam-spray on and wipe off. The most economical glass cleaner is a mixture of 1/3 white vinegar and 2/3 water and wipe with a newspaper. The newspaper does not leave lint on the glass. On mirrors do NOT use abrasives, alkali, ammonia or acids as these destroy the silver backing.
3Why do edges of a mirror turn black?
Most often it is in bathroom mirrors were moisture and contaminates in the air attack the silver backing causing discoloring and flaking. Soapy water or incorrect cleaning liquids accumulate on the edges of the mirror eroding the backing. At Glass Depots USA we try to avoid the deterioration by sealing the edges of the mirror.
4What is the difference between tempered and laminated glass?
Tempered glass is a safety glass used in doors and windows where safety is a concern. It is manufactured by heating and then rapidly cooling the glass. This cooling process causes the outside surface to form a hard “skin” which is up to 7 times stronger than “annealed” glass. When broken, it shatters into small, less harmful fragments. Laminated Glass is both a safety and security glass. It is made by bonding two pieces of glass together with a plastic inner layer called polyvinyl butyl. The plastic prevents the glass from separating when broken, which reduces the danger of serious lacerations. However, laminated glass cracks much easier than tempered on impact.
5Why do insulated or thermal glass units fog up?
All insulated units will eventually fail. Insulated glass is made using two pieces of glass bonded together with a spacer creating an air space in the center that produces the insulation. Even when properly installed, heat, cold, expansion, contraction, uv-rays and moisture eventually cause seal failure. Glass Depots USA provides a limited 5 year manufacturer’s warranty.
6What do I do if only one side of my window is broken?
Unfortunately, you have to replace the whole unit (glass portion). Due to the way insulated windows are produced, both pieces have to be replaced. Sealing a unit has to be done at the factory and cannot be done on site.
7Where can I find replacement parts for my shower door?
Great question with a not so great answer. Shower door manufacturers are terrible at putting their name on their product. Most manufacturers buy their glass and metal from different suppliers. The best place to get parts for your door is from the company your purchased it from. If you are building a new home, be sure to keep a list of suppliers where your builder received his products from. If you don’t know where your shower door was purchased from, then may the luck of the Irish be on your side. Taking a picture of the part you need and calling/visiting local glass shops would be your best bet. I can look at a part right away and tell if it came from our shop or not. Sometimes, parts can be interchangeable, but not always. Spending the small amount of money to give it a try can sometimes be better than buying a whole new door.
8What is the difference between regular glass and safety glass?
Annealed glass or float glass is the basic form of all glass. When broken, annealed glass will shatter or break into large fragments. The thicker the glass, the more dangerous the fragments. Safety glass or tempered glass is glass that has been processed by a heating it to make the glass stronger. When broken, tempered glass will shatter into small fragments, making it less likely to cause severe injury. Another safety glass is called laminated glass. Laminated glass is when two pieces of float glass are bonded together to keep the glass from breaking apart. Laminated glass is typically used in auto glass. All shower doors, by most building codes, must be tempered and must display the tempered stamp or “bug” somewhere on the glass itself. The “bug” will also display the name of the company who tempered the glass. This may be different from the manufacturer of the shower door but is still a reference when determining where the door came from.
