  • What Are Vinyl Replacement Windows?

    Vinyl is synthetic resin and polymer and is used extensively in the modern window industry.

    Vinyl is one of the most versatile plastics in the world. It is not a natural material, but rather a man-made synthetic material. It is engineered from ethylene (found in crude oil) and chlorine (found in regular salt). The manufacturing process combines these substances to form Polyvinyl Chloride (PVC) resin which is more commonly known as Vinyl.


    • Vinyl is resistant to moisture and humidity
    • Vinyl is a very strong and durable plastic material
    • It can be manufactured in a variety of colors, both transparent and solid
    • Vinyl is a very low cost material to produce
    • Vinyl requires little maintenance
    • Improved thermal efficiency and lower energy consumption. Vinyl retains heat during winter and keeps heat out during summer
    • Low Maintenance – Vinyl windows are scratch resistant and provides a protective coating that adds strength and durability to your windows
    • Vinyl is inexpensive so your windows cost less
    • Vinyl windows are available in a variety of colors, sizes, and style options.
  • When Should I Replace My Windows?

    We have put together some vital signs that you need to replace your windows now:

    Shabby Appearance

    First of all, you should check the appearance of the windows. If they are dull and shabby, you must know it will affect the appeal of the house and degrade the resale value of the house.

    Difficulty Operating

    First of all, the most obvious sign would be difficulty in operating the windows. If you are finding it hard to open or close the windows, it means the windows are quite old and you might need to replace them soon with new ones.

    Window Damage

    Are there holes in the windows? Or have they become warped? Sometimes, you might also notice water below the windows. These are common signs of damage which have to be repaired but repairing is not a permanent solution and it will again happen. Instead of wasting your money on repairs, get these replaced.

    Mold Growth

    Sometimes windows accumulate a lot of moisture which leads to the growth of molds. If there is a growth of molds in your house, it will eventually damage your window and spread different kinds of virus and bacteria. The only solution to this problem is changing the windows of your home.

  • What is Low E?

    Low E (low emissivity) coatings control the transfer of heat through windows with insulated glazing. Applied on glazing or glass, Low-E coatings typically cost about 10-15% more than standard windows. However, they reduce energy loss by as much as 30-50%.

    Microscopically thin, a Low-E coating is virtually invisible. Composed of a metal or metallic oxide layer, it’s deposited directly on the glass pane surface(s), reducing infrared radiation, therefore lowering the temperature of the glass resulting in a lower U-factor for the window. Different types of Low-E coatings have been developed for varying degrees of solar gain (high, moderate or low). Low-E coatings also reduce a window’s visible transmittance unless a spectrally selective coating is selected.

    In hot climates, homes with east and west-facing windows and unshaded south-facing windows, Low-E coating should be applied to the outside pane of glass. However, cold climate homes with windows designed to retain heat energy during winter months should apply Low-E coating to the inside panes. Low-E coatings are applied in either soft or hard coats. Soft Low-E coatings degrade when exposed to air and moisture. They’re easily damaged and don’t last long. Therefore, manufacturers restrict their application to insulated multiple-pane windows. For a more durable solution, Hard Low-E coatings can be used in add-on (retrofit) applications.

  • What is Argon/Krypton & Why is it Used?

    By filling the space between layers of glass with a less conductive and more viscous slow-moving gas you minimize the convection currents within these spaces which results in a reduced transfer of heat between the inside and outside.

    The introduction of argon and krypton gas fills by manufacturers looking to improve window efficiency resulted in a measurable improvement in thermal performance. Inexpensive, nontoxic, nonreactive, clear and odorless, argon has proven to be a perfect gas fill. The optimal spacing for argon is about the same as for air (1/2 inch or 11-13 mm).

    Krypton is also nontoxic, non-reactive, clear and odorless, yet offers even better thermal performance…at a greater cost to produce. Krypton is preferred for glazing spaces that are thinner than normal, such as ¼ inch (6mm). The optimum gap width for krypton is 3/8” (9mm). To maintain a comfortable price point without compromising thermal performance, a mixture of krypton and argon gases is sometimes used.

  • What is Partial or Full Capping?

    Most homes have exterior window trim that is made of wood, which can cause a series of issues, including rotting, peeling and cracking as the elements take their toll. Wood requires maintenance in the form of prepping and painting every few years. Custom Window PLUS can eliminate the need for ongoing maintenance by wrapping the wood with aluminum and sealing it from the elements, creating a long-lasting beautiful trim that’s maintenance free.
  • What Colors Are Available?

    There are many optional colors from which to choose. Please contact us today to ask our sales representative for available color samples at the time of your FREE estimate & consultation.
  • Do the Windows Tilt-in for Easy Cleaning?

    Absolutely! Our innovative tilt-on-command feature makes cleaning your Custom Window PLUS windows a simple, easy task. The dual cam lock ensures a weather-tight seal as well as added security. Your Custom Window Plus representative will be happy to provide information on the proper method for tilting your windows for easy cleaning.
  • Do the Windows Come with Screens?

    Yes, our windows come standard with ½” screens that move up and down to accommodate whatever part of the window you’re opening. Full screens are available for a nominal fee.
  • Are the Windows Installed from the Outside or the Inside?

    Typically our windows are installed from the inside, and one at a time. During installation, windows are out for only 3 to 4 minutes so cold and inclement weather should not be an issue.
