What Makes Replacement Windows Energy Efficient

Keeping your home cooler in the summer and warmer in the winter is of the utmost priority for the purposes of comfort and saving money. The majority of window contractors and other home remodelers typically agree that one of the best ways to save energy in your home is with replacement windows. The energy-saving technologies with which modern windows are equipped really help to drive energy costs down. Unfortunately, many homeowners aren’t quite sure what they’re looking for when it comes to such things, which is why we’re here to help you understand how these technologies work to save you money.

How Windows Save Your Money

  • Multi-Pane Construction: A well-known quality of modern replacement windows is their multi-pane construction. The majority are available as double-pane and some companies even offer them triple-pane windows. Multi-pane construction is so effective because it provides multiple obstacles through which heat must transfer. Another benefit is that multi-pane construction tends to mean the window frames are of more solid construction, which provides you with greater security.

    Multi-pane construction is nearly imperative to protect your home from heat transfer; a window’s ability to protect against heat transfer is indicated on the NFRC ratings for U-Factor and Solar Heat Gain Coefficient.

  • Insulating Gas Fills: This feature is only available with multi-pane windows and primarily comes in two different types, Argon and Krypton. Krypton is a denser gas so it does have better insulating qualities, which results in saving you more energy.

    Insulating gases increase the ratings for U-Factor and Solar Heat Gain Coefficient by protecting against heat transfer with their qualities of density.

  • Low-E Glass: Low-E Glass, also known as insulated glass, is glass designed with low-emissive qualities. This means that its ability to reemit radiant heat into your home is lower, considerably cutting down on energy transfer coming from the sun.

    Another great benefit of Low-E glass is that it helps reduce Visible Transmittance, which helps protect the interior décor and furniture from fading.

  • Multi-Chamber Frames: The majority of vinyl window frames are constructed with a multiple chamber design. The multiple chambers create an insulating dead space or thermal break within the frame. This quality reduces the amount of heat transfer and air leakage that could potentially take place through the frame.

    The thermal break within the frame reduces heat transfer into and out of your home through the window frame by opposing conductive heat transfer. Furthermore, any air leakage that tries to take place in this area is caught in the chamber and strengthens the insulating factor.

  • Spacers: Several modern multi-pane windows are equipped with a spacer in the frame to keep insulating gas from leaking. Spacers also work toward keeping the glass in place, and even improves the condensation rating. There are many types of spacers available but one of the most popular types the warm edge spacer.
