• What are various windows made of and what will work best for me?

    Basically there are three types of material used. Aluminum windows, with their easily scratched painted surfaces, conduct both heat and cold, so they’re very poor insulators. Wood windows, which require constant painting and caulking, can absorb moisture, making them difficult to open and close. They can even rot. Gentek’s solid vinyl windows, however, never need painting and won’t show scratches, because the color goes throughout the material. This is why vinyl windows are quickly becoming the most popular choice for both new construction and replacement applications.

    Gentek vinyl replacement windows are custom-made to the precise measurement of your window openings. This is a significant advantage over “ready-made” or stock windows, which are adjusted to fit your home, thus compromising the energy efficiency and appearance. Stock-sized windows also may require extensive carpentry work both inside and outside your house, which can be costly and inconvenient. Gentek custom-sized windows are meticulously crafted to beautify your home while ensuring a weathertight fit.

  • Is there any difference in how windows are made?

    There are two basic types of construction:  mechanically fastened windows that are screwed together at the corners, and welded windows that use a chemical or heat process for joining corners. Gentek produces both types. Our welded windows utilize state-of-the-art welding technology and equipment to ensure superior strength and durability. Our mechanically fastened windows feature a unique overlap corner design for extra strength; beware of windows with mitered corners screwed together or chemically welded corners, as they probably won’t perform as well for you.
  • Can I replace my old windows with different styles or types?

    Yes, and Gentek offers a full selection of window styles and configurations to let you design the ideal system for your home. Choose from single hung, double hung, sliding, casement, awning, bay and bow, garden, picture and specialty shape windows, along with patio doors. You may want to consult an independent design specialist to determine the window system that best complements your home’s architectural design.  
  • What about strength, protection and noise reduction?

    You should look for a window that offers both superior strength and energy efficiency. Gentek’s computer-controlled process ensures a perfectly square window sash and mainframe with superior strength. And for exceptional energy efficiency, a full interlock at the meeting rail helps protect your home against the elements, or unwanted intrusions. In addition, our insulating glass unit traps dry air, creating an exceptional comfort barrier.

    Moreover, homeowners with Gentek windows say there’s a noticeable reduction in the amount of noise that enters their homes. A full interlock system at the point where upper and lower sashes meet helps stop air infiltration while providing an additional barrier against unwanted intrusions.

  • Do Gentek windows require much maintenance?

    Because our frames and sashes are made of vinyl, you can say goodbye to painting and caulking. Gentek windows won’t stick, and there’s no need to remove storm windows in order to clean them. In fact, for many window styles you can easily clean your windows from inside your home.  An occasional wipe with a damp cloth will keep your windows looking like new for years to come.
  • I have been reading about different test results on windows. How should this impact my buying decisions?

    Be careful when looking at extremely specific results since many of them do not really indicate how well the window will work for you. Some apply to just certain parts of the window, like the glass and its R-value, and do not give an overall picture. Tested in nationally certified labs and our own modern test facility, Gentek windows are engineered to provide the optimum in energy savings and are monitored by the National Fenestration Rating Council.
  • What is more important in saving energy, the frame or the glass?

    Since 80% of a window is glass, real heating and cooling savings come from what is known as “improved glass performance,” not a high R-value on the frame. Gentek uses the latest technology, known as a warm-edge spacer system. This spacer system helps to improve the performance and the longevity of the insulated glass unit and is standard on all Gentek windows.
  • What energy-saving options should I know about?

    You should give careful consideration to Gentek’s BarrierXP® insulated glass package, featuring Low-E glass and argon gas, along with the PPG Intercept Warm-Edge Spacer System. Low-E glass is an excellent barrier against ultraviolet rays which fade carpet, furniture, draperies, and even woodwork. Argon gas is colorless, odorless, nonflammable, nontoxic, and above all, a safe, inert gas that is heavier than air. Not only does argon gas help to increase the energy efficiency of a window, it helps to make your home quieter as well.  

    Many Gentek windows upgraded with a BarrierXP insulated glass package meet the latest ENERGY STAR® requirements. Consult your window professional for the optimal glass package required for your home and climate zone.

  • What is the ENERGY STAR® Program?

    The ENERGY STAR program was created by the Environmental Protection Agency and the U.S. Department of Energy to help consumers recognize energy-efficient products. This program also promotes the environmental and economic benefits of these products through the ENERGY STAR label and other program activities.
  • Will Gentek windows be a good investment?

    Yes, for a variety of reasons. First, you may realize savings on your heating and cooling bills. Second, they’re virtually maintenance-free, which eliminates painting costs. And finally, the transferability of one of the strongest warranties in the business may likely add to the resale value of your home.
  • Aren't all window warranties the same?

    No, and there are as many warranties as there are window manufacturers. Some brand name factory warranties cover just the sash and frame.  The rest is left up to the local fabricator who may or may not cover it. Your warranty is only as good as the company behind it. With Gentek, your unit is warranted from the extrusion and parts to the glass and construction by our Lifetime Limited Warranty,* with transferability provisions. It’s one of the most comprehensive available, just what you’d expect from an industry leader.
