  1. What is a Replacement Window?

A replacement window is as its name suggests: a window designed to replace an existing unit in a home. They are different from new construction windows in that they are ideally custom-fit and manufactured to ensure a good fit in an existing frame. Essentially, a replacement window is designed to be placed within a window opening, while a new-construction window requires a new opening to be made to accommodate it.

  1. Why Should I Replace My Home’s Windows?

There could be a number of reasons why you would need to replace your old windows. This could include:

Old and damaged windows are unappealing in appearance, making your home look unkempt and neglected. By replacing your windows, you can improve the look of your home, both on the outside and inside.

  • Higher home resale value. Even if you don’t have any plans of selling your home soon, wouldn’t it be nice to know that replacing your old windows can actually increase your property’s value? This is because home buyers appreciate the idea that they won’t have to replace windows themselves after moving in and that they are getting a property with energy efficiency features.

The “e” in low-E stands for emissivity, which is a surface’s ability to radiate or emit heat. Low-E glass is a type of glass fitted with a microscopically thin, invisible layer of metallic oxide directly onto its surface.

When a low-E coating is applied on the outer side of the glass, it reflects UV and infrared rays from the sun, keeping both from entering the home. When the low-e coating is applied on the inner side of the glass, it bounces heated indoor air back to the home, preventing energy wastage.
