Prevalent Exteriors Window Replacement & Repairs



Windows add subtle character to a home and act as a channel for light and air to either come in, or be prevented from entering the house. You can make this the focus of a room or even the whole house, blending in your surroundings and controlling what you see. Of course every homeowner would like for their home to be visually appealing, but protecting their home from the elements is vital for comfortable living. Transform your home with new replacement windows by Prevalent Exteriors, designed to be stylish and sensible for the discerning homeowner. Just like all good windows, they capture natural light throughout the day and make your rooms light, cheery and bring in much needed ventilation, ensuring you have well-aired and fresh living areas.

    More Information:


      ENERGY STAR labeled windows, doors, and skylights are twice as efficient as the average windows manufactured just 10 years ago. They help cut your heating and cooling costs and can make your home more comfortable without compromising cost, comfort, versatility, or style. These high-performing windows are available in every operator type, including single- and double-hung, casement, horizontal slider, fixed, picture, and patio slider. And, they are manufactured with most common frame materials, including aluminum, fiberglass, vinyl, and wood.


      Glass Coatings

      Many windows and doors are available with Low E glass. A transparent metallic oxide coating applied to the glass surface allows short-wave energy to pass through but reflects long-wave infrared energy for greater thermal efficiency.

      Gas Fill
      The space inside an insulating glass unit—between the glass panes—may be filled with Argon gas, an odorless, non-toxic gas that is six times denser than air. This acts as an added barrier for a higher level of efficiency. Optional Krypton gas may be specified in some glass packages.

      Laminated Glass
      Some glass packages contain laminated glass. A transparent interlayer is adhered to a pane of glass, acting as a barrier against energy loss and noise.
