Energy Efficiency Basics
When it comes to windows and energy efficiency, what is the first thing I need to know?
Replacing your old windows with more energy efficient units will not only help you reduce your utility bills, it will also make your home more comfortable. Choosing the right windows and doors can help you regulate the amount of heat coming in and out.
How do I know if my windows and doors are energy efficient?
Certification programmes offered by certification bodies such as the National Fenestration Rating Council (NFRC) and ENERGY STAR can show the energy efficiency rating of windows and doors. Various performance ratings, such as U-factor and solar heat gain coefficient, measure how effective a product is at insulating and blocking heat from the sun, among other things.
NFRC
Energy efficiency is achieved through the use of various window and door technologies. Low E coatings, frame materials, glazing types, spacers, gas fill, and weather stripping all contribute to efficiency. Energy ratings for windows and doors are certified by the National Fenestration Rating Council (NFRC). Browse the NFRC database to see their ratings for any Marvin product.
Energy Star
Protecting the environment by reducing greenhouse gas emissions is achieved through low energy consumption and low cost of products. ENERGY STAR is designed to encourage energy-efficient practices and support sustainable development. It provides a trusted choice for consumers looking for environmentally friendly options.
Energy Efficient LOW-E Glass
Low-E glass is a specialized energy-efficient glass with a thin, transparent coating that reflects heat. It helps keep interiors warmer in winter by reflecting heat back inside and cooler in summer by blocking heat from entering. Low-E glass also reduces UV light penetration, protecting furniture from fading, while improving insulation and energy efficiency. Lower energy consumption, enhance comfort, and contribute to environmental sustainability.
Terms of Energy Efficient Windows and Doors
Insulated Glass (IG)
Two or more glass panes separated by energy efficient inert gas or air to reduce thermal transfer.
Gas Fills
Argon or krypton mixes slow the movement of warm and cool air in IG airspaces and improve thermal performance.
Low E
Low E stands for low emissivity. Microscopically thin, transparent metal or metallic oxide layers deposited on a glass surface suppress radiative heat flow and reflect interior infrared energy (heat) back to the inside, reducing heat loss through the glass. Various Low E coating options can manipulate heat gain to match different climate needs.
Visible Transmittance
Visible transmittance is the amount of visible light transferred through a window. Low E coatings can reject solar heat gain without significant reduction to visible light passing through the glass. When you look at the ratings, remember that the higher the number given for visible transmittance, the more light that can come in.
U-Factor
Simply put, U-factor measures how well a window keeps heat inside your home. It’s a measure of total heat flow through a window or door from room air to outside air. Lower numbers indicate greater insulating capabilities. It’s a particularly important measure for climates with colder winters.
Solar Heat Gain
If U-factor denotes how much heat leaves your home, the Solar Heat Gain Coefficient (SHGC) measures how much radiant heat enters your home. The lower the number, the less heat a window lets in.
