The following is a list of frequently asked questions. If you have a question not mentioned below, please feel free to contact us for additional information.
Q: How can I tell if I should replace my windows?
A: Look for the following:
Are your current windows energy efficient?
If your windows have wood frames, are they showing rot?
Do your present windows get a lot of condensation on the inside?
Do fabrics, drapes and carpets show sun fading within a short time (1 year)?
Are you feeling drafts around your windows?
Q: When selecting a product and an installer, what should I look for?
A: Choose an installer with a proven track record and good local references. Your choosen products should have a good warrantee, be, at least, double pane construction, and be suitable for your application.
Q: Is low-e glassdesirable? Why?
A: Low-emissivity glass (low-e glass), has a very thin coat of material on the glass to make it more efficient, especially in very sunny, hot areas such as the west coast. It helps reflect standing heat away from the surface of the glass, keeping unwanted heat out in the summer and desired heat inside in the winter. Low-e glass is the most cost effective way to increase the energy efficiency of the windows.
A: Low-e coatings can also help reduce furniture and carpet fading by reducing the amount of ultraviolet (UV) radiation that enters the home. Harmful ultraviolet radiation can alter the chemical structure of dyes and other colorants in carpets and furniture causing fading.
Q: Once ordered, whatis the wait time for delivery of my windows?
A: Custom orders typically take seven to ten working days to manufacture.
Q: Can Miller Glass custom-build windows to fit an odd-sized opening?
A: Yes, Miller Glass' suppliers custom-build windows to the nearest 1/8" increment and can produce a variety of shapes and sizes.
Q: My windows get condensation on the inside. What causes this?
Condensation is caused by humidity (the amount of water vapor present in the air). When this water vapor encounters a surface at a cooler temperature than that of the surrounding air, it turns to visible droplets of moisture. Double and triple glazed windows reduce the condensation effect somewhat, and vinyl window frames won't be subject to rot like older wooden frames are. You can reduce the moisture in your home by using fans in bathrooms, kitchens and laundry rooms to circulate the air. A dehumidifier may be helpful in removing excess humidity from the air.
Q: What does AAMA and NFRC certified mean to me?
A: The American Architectural Manufacturers Association (AAMA) sets all performance standards, product certification and educational programs for the window industry. When a product passes AAMA tests, it ensures long, reliable service if properly installed and maintained correctly. The National Fenestration Rating Council (NFRC) is a non-profit organization created by the Department of Energy and supported by the window, door and skylight industry to provide consistent ratings on window, door and skylight products pertaining to the energy performance of that product. A NFRC label is placed on window, door, and skylight products to inform consumers about the U-factor of the product. Factors taken into consideration for the U-factor rating include the ability of the product to block warming caused by sunlight, light transmittance and air infiltration through cracks in the product assembly.
Q: What is the best way to evaluate a window's energy performance?
The easiest way to compare energy performance of different windows and doors is to read the National Fenestration Rating Council (NFRC) label. It provides valuable energy efficiency information about the product including the u-value, solar heat gain and visible transmittance values. Also, check to see if the product is ENERGY STAR® qualified.
Q: You spoke of a rough opening, what is that?
A: It's the opening in the wall frame that a replacement window must fit into. As a rule of thumb, the rough opening should be a half-inch taller and wider than the frame of the window being installed.
