New house windows come in many shapes and styles, with every option giving your curb appeal a beautiful boost! However, windows are also excellent insulators that increase indoor comfort. This guide will give you insight into how you can choose the most energy-efficient windows in New England.

Insulating Materials

The window material you choose for your home makes a difference in performance. Vinyl is one of the top choices for window replacement materials. When professionally installed, vinyl frames are capable of reducing drafts and preventing energy from escaping. This keeps your HVAC system from overworking and causing your utility bills to rise.

The most insulating vinyl frames include foam inside. This provides another barrier against energy loss and keeps the windows performing at peak condition.

Warm Edge Spacers

Inside the most energy efficient windows, there is spacer technology that keeps the glass panes together. This spacer helps improve a window’s performance in several ways. First, it keeps homes warmer in the summer and cooler in the winter by reducing thermal transfer. It also helps prevent condensation from forming around the edge of the glass.

When searching for energy efficient replacement windows, look for acrylic-bonded and ultra durable spacer technology. Meanwhile, a warm edge steel spacer system does not conduct moisture.

Energy Efficient Gases

When it comes to making your home more energy efficient, a lot of the power comes from the glass packages. Manufacturers fill invisible energy-efficient gases between the window’s glass panes to provide additional insulation.

Argon Gas

When you hear about replacement windows containing energy efficient gases, this is likely a reference to argon gas. Argon is a gas that’s denser than air. Its purpose is to enhance the thermal efficiency of the window and essentially create an extra barrier to block energy loss.

When you see windows advertised at bottom dollar prices, it likely does not contain argon gas. You’ll pay less money upfront, but you won’t see a significant difference in your energy bills.

Krypton Gas

Argon gas is a popular energy efficient gas for a replacement window, but it’s not the only option. Krypton is even denser than argon, and it also costs more. Krypton gas fits well in the tight chambers of triple-pane windows, making them ultra-efficient replacement windows for your home.

Keep in mind that krypton gas can increase the u-value of a window by up to 27%.

Low-e Glazing

Manufacturers apply an invisible Low-e coating to the glass of your replacement windows. Manufacturers apply low-e coatings in several areas, including:

  • Outside surface of the exterior glass
  • Inside surface of the exterior glass
  • Outside surface of interior glass
  • Inside surface of exterior glass

During the winter, low-e can help keep your home warmer by reflecting heat from a room back inside. This helps prevent energy loss, which helps keep your utility bills low during the coldest times of the year.

Without these gases, energy can easily be lost through the glass panes. This makes your windows much less efficient while your energy bills remain high.

Triple Pane Glass

Long ago, replacement windows had a single pane of glass. This proved to be quite inefficient and didn’t provide much for energy savings. Eventually, dual pane windows became the norm in homes across America.

Today, a third option is available: triple pane glass. Triple pane is one of the most energy-efficient options that you can choose for your home. The third pane of glass provides an additional barrier against the elements as well as energy loss. When you combine triple pane with all of the other energy-saving technologies available, you can save potentially hundreds of dollars each year on your energy bills.

Expert Installation for Energy-Efficient Windows

Selecting certified and insured window contractors is imperative to the product’s performance.

For example, during the winter, energy loss is a major consideration for homeowners. While inefficient windows can lose up to 25% of your home’s energy, the least of your worries is what is potentially lost during the installation process.

This is how window installation works in the winter:

  • Professional window contractors only replace one window at a time during the winter. Using this approach ensures that little-to-no energy is lost during the process.
  • Plastic tarps are placed over the window opening to prevent further heat loss.
  • Expert window contractors can typically replace a window within 20 to 30 minutes.
  • Caulking and trim are added after the window is replaced, which can add on another 20-30 minutes of work.
  • If the window is measured correctly, the gap around the window will be minimal—around ½” to ¾”. This is enough room to ensure that the vinyl can expand and contract when the weather becomes hot and cold.
