Frequently Asked Questions


About Buying Sun Products

Q. Where can I buy Sun windows and doors?

A. Sun Window products are distributed regionally in KY, TN, IN, OH, IL (and surrounding areas) through Authorized Dealerships and Direct Builder Sales (in select areas). To find the Dealer or Representative nearest you, visit our Dealer Locator Map.

Q. How much do they cost?

A. Sun Window products are very competitively priced. Sun Windows, being a regional manufacturer, avoids the high cost of large over-head and national advertising, as well as maintaining lower freight costs on regional deliveries. These savings allows Sun Windows to put more into the product and pass greater savings on to you.

Request pricing using our online form and we will be glad to provide you a quote on your project.

Q. Do you offer computer designs and quoting for my windows and doors?

A. Yes. Sun Windows can provide a detailed print-out of your complete order, listing the specifications for your window and doors, including the location of each and the rough openings. This service will help you and your builder coordinate the layout of your windows and doors and prevent errors in framing sizes.

Q. How do you compare to other window and door brands?

A. Sun is competitive in quality and pricing with most of the nationally recognized, brand name windows and doors. We encourage you to send us your "other brand" specifications and let Sun prepare you a competitive analysis. This will provide you with an equal comparison of matching products and options. We welcome these questions and the opportunity point out what makes Sun such an outstanding value. Being the biggest is not always best.

Q. Can I get professional window help to better determine my window selections?

A. Sun representatives can be very helpful in working with you and the distributor to better design the windows to best suit your home needs and at the most affordable prices. Their extensive product knowledge will aid you in the selection of Sun products and options. They can also provide you with a detailed quote showing actual drawings of the products as well as details of the sizes and options for your new project.

Q . Can I purchase windows outside your Marketing area?

A. This is question we hear a lot. Our primary market is in the Midwest within approximately 250 miles of our Owensboro, KY Factory. It is possible to purchase outside this circle. Send us your inquiry by E-mail or using our online contact form, and we will attempt to help where we can.

Q. Can I purchase small parts from you?

A. Yes, but properly identifying the part can be difficult, especially on older products. Most customers send a sample of the part needed and we attempt to provide a replacement. In some instances parts for older products are no longer available.

Q. How are your Products delivered?

A. Most Sun Windows and Doors are delivered by our own fleet of delivery trucks. Sun Windows also uses factory trained loading and delivery personnel. This is another great reason to select Sun Windows. You not only get great products, you get the whole Sun Team working for you. In some instances, especially for locations outside of our primary market area, 3rd party freight may be the best option. This would be handled by special quote. Many parts can be shipped using UPS or FedEx.


About Sun Products

Q. What is the exterior covering on your Clad Wood Windows?

A. Unlike many companies using thin vinyl and soft roll aluminum, all SunClad Windows feature heavy extruded aluminum exteriors to include the main frame with its intergral nailing fin as well as the sash or door panel. This provides exceptional strength and long life for the windows and doors. The exterior finish is our high durability powder coat finish.

Q. What colors do Sun Window’s come in and can I change the color in the future?


Clad Exterior Color Options

SunClad™ Exterior Colors

Sun's High Durability Powder Coat Finish is available in a wide range of Standard Colors, Feature Colors, and Metallic Finishes as well as in Custom Match Colors. You also have the option of using various color combinations to create a unique visual accent. Color cards available upon request.

Custom Match Colors

Multi-Color Combinations

About Product Performance

Q. Are Sun Windows Energy efficient?

A. Yes, Sun windows and doors are very energy efficient. Sun Windows is a certified partner in the NFRC Certification program and the U.S. Department of Energy and the Environmental Protection Agency Energy Star® program. Sun Windows is proud to be part of these energy savings certification programs.

Q . Do Sun Windows have R-Value ratings?

A. All Sun Windows are tested by independent testing agencies and each product lists the tested results. The test values are documented in U-values. U-values measure the amount of energy transferred through a unit, where R-values measure the resistance to energy flow. These values are simply mathematical inverses. Some companies will convert U-values to R-values to try to give the customer an "insulating value" similar to what is provided by wall insulation. U-values are the industry standard value for comparison of window and door energy performance. Our Performance information is available in our Technical section.

Q. Do I really need the warm-edge insulated glass spacer or is the old design aluminum spacer adequate?

A .Sun Windows uses a warm-edge spacer system on all window and door products. This spacer reduces the conductivity of the insulated glass edge by 75% over old design aluminum spacers and produces more even glass temperatures over the entire insulated glass area. The result is a warmer glass unit that is less susceptible to glass stress. See our featured IG Spacer, Duralite™ for more information.

Q. Do I get Energy Tax Credits?

A. Tax credits imbedded in H.R.4, a new comprehensive energy bill is available until December 31, 2006. The bill also includes tax credits for commercial buildings. For more information go to the Primary Glass Manufactures Council web site at,

Q. Why do my windows "fog-up" when it is cold outside?

A. If moisture appears on the inside glass surface of your windows or doors (this is called condensation) you have an imbalance in your homes environment. Please read our article on Condensation for more information.

About Testing & Certification

Q. Are Sun Windows tested and certified?

A. Yes. Sun Windows participates in several certification programs to ensure that our products are consistently manufactured within the required standards. Sun participates in the following certification programs and testing standards: WDMA Hallmark Certification program, SIGMA Insulated Glass Manufactures Association, Energy Star®, NFRC National Fenestration Rating Counsel and ASTM.

Q. Why do the Sun Windows test show some of the lowest air infiltrations in the industry?

A. Sun focuses on providing Energy Efficient products. One aspect of this is minimizing air leaks or infiltration. The designs of Sun products effectively seal-out air infiltration, providing excellent energy efficiency and indoor comfort. Air infiltration is tested in accordance with ASTM:E 283-91 and AAMA/NWWDA 101/LS.2-97.
