By replacing old, inefficient windows, you are giving your home a chance for an updated look as well as improved efficiency, comfort, and value. You and your family also get to enjoy savings on your monthly energy bills. To ensure the success of your window replacement project, you need to choose the right products. Here’s a simple guide to the window features that guarantee quality.
Today, there are a number of options available for you to choose from when it comes to window replacement framing materials. However, if you wish to maximize your investment, you must choose one that fits these requirements:
• It must have outstanding insulation properties
• It must be able to reduce heat transfer significantly
• It must be durable, with the ability to resist weather, moisture, and pests
• It must be low-maintenance
Among the newer materials that offer these characteristics is Fibrex, a type of composite frame that is twice as strong as steel, and lighter and more durable than vinyl or fiberglass. Its insulation properties are also comparable to that of wood. Because of its durability, it also requires minimal maintenance.
All window glazing may look the same at first glance, but there are vast differences to their specific features. To make sure that you are getting an energy-efficient window, it must have the following glass features:
• Double or multiple panes
• Low-emissivity glass coating
• Inert gas filling
• Warm-edge spacers
• High-quality seals
Energy Efficiency Values
To know for sure if a replacement window is energy-efficient, it must have NFRC rating values that are within recommended ranges.
• U-Factor – measures the rate of heat loss through a window assembly. The lower the value, the better.
• Solar Heat Gain Coefficient (SHGC) – measures the fraction of incident solar radiation that a window lets through. The lower the value, the better.
• Air Leakage (AL) – measures the rate of air infiltration and leakage that occurs around the window frame. The lower the value, the better.
• Visible Transmittance (VT) – measures the fraction of visible, natural light transmitted through the window. The higher the value, the better.
At this point, you should already have an idea about the features that you should look for in a product to ensure window replacement success. To complete this guide, we are giving you more tips and recommendations so you can avoid window replacement mistakes. Stay tuned for our next post!
