Windows play an integral part in a home’s energy costs. Depending on their heat loss resilience, windows will affect how much electricity your home consumes when heating and cooling the interiors. If you’re planning to get a new window installation, consider the following ways to maximize energy-efficiency.

3 Tips for Energy-Efficient Window Installation

1. Assess the Glass

Before you begin your new window installation, you’ll need to spend time shopping around for the right materials. Energy Star and the National Fenestration Rating Council (NFRC) both list their energy-efficiency on their labels. The label will state the window’s U-value, which pertains to its heat loss resistance, and the Solar Heat Gain Coefficient (SHGC), which measures the amount of solar heat penetrating the glass.

Choose a lower U-value and SHGC for better efficiency, especially in colder climates. Be sure to check the Visible Transmittance as well, which estimates the amount of light transmitted inside your home. The higher the number, the more light can pass through the glass.

Apart from the ratings, pay attention to the kind of glass, the number of panes, and gas filling. Choose a double-paned, argon-filled window with Low-E glass for improved insulation. If you’re living in extremely cold climates, three-paned windows filled with denser gases may be better in the long run. 

2. Pick the Right Frame

Not all frames are made equal, so ask your window installation company which will fit best in your home. Choose from vinyl, aluminum, wood, wood-clad, and fiberglass. Among the five, vinyl is the least expensive but still delivers excellent energy-efficiency. Wood offers the best insulation; however, it is high maintenance compared to the others. Aluminum performs well in coastal areas but does poorly in terms of heat transfer and loss. Wood-clad may offer the best of both worlds but remains susceptible to water intrusion and moisture damage. Fiberglass is an excellent choice but comes with a hefty price tag. 

3. Have It Professionally Installed

Proper window installation ensures that everything is according to the manufacturer’s specifications and doesn’t nullify the warranty. Work with a professional from start to finish since they can also give tips on the best type of windows to install. An experienced contractor will perform waterproofing before installation, then caulking and flashing afterward to prevent water leaks and air drafts.
