What makes a window qualitative?

Window replacement will turn out to be your most significant expense. But we can reassure you that it will be the best decision you’ll ever make. So, based on our experience with new and old windows, we shared our insights on what makes a window qualitative. Pay close attention to all the details below, and you’ll be successful in choosing new windows.

1. Window frame

Our experts recommend you pay close attention to window frame types. There are quite a few materials you can choose from. It is best to consider your house’s style and existing window types to make the best decision. Here are the leading window replacement frame materials you can opt from:

  • Aluminum – a lightweight solution that allows you to customize your frame
  • Wood – a stylish solution with excellent insulation properties
  • Vinyl – an affordable and low maintenance window frame
  • Composite – an eco-friendly solution that can be painted to resemble wood frames
  • Hybrid – a mix of the best materials available

2. Windowpanes

Next, you’ll have to consider the window panes. Several panes mixed with coatings and glazes can improve interior comfort and insulate your home.

You can choose from four standard treated windowpanes: single, double, triple, or quad glazed. These can prevent UV damage and improve energy-efficiency.

You can select from three types of window panes coating: low-emissivity, reflective, and spectrally sensitive. These can keep out the heat or cold, preventing interior temperature fluctuations.

3. Window spacers and fills

Spacers and fills offer extra insulation to your windows. Spacers are set up between glass panes inside the window frame. They prevent contraction or expansion of the pane, which decreases the chances of condensation or similar moisture problems. Fillers represent inert gases inserted between the panes to prevent the outside temperature from entering your home.

4. Energy-efficiency

The goal of any windows replacement project is to improve a home’s energy-efficiency. There are five performance categories to consider:

  • U-factor stands for insulation abilities, and the lower the number, the better the choice
  • Solar heat gain coefficient stands for blocking solar heat, and the lower the number, the better the choice
  • Air leakage refers to air going through window spaces, and the lower the number, the better the choice
  • Visible transmittance refers to light passing through the window
  • Condensation resistance refers to how the window deals with water between the panes, and the higher the numbers, the better choice


This is how to tell if your windows are of good quality. We highly encourage you to ask a window contractor for additional information on the topic. In this way, you will make the best decision for your next window replacement project.
