If you have questions about the energy efficiency of specific brands or other window characteristics, talk to the window experts at Brennan Corp today.Benefits of ENERGY STAR Qualified Windows, Doors, and Skylights However, starting with a sound basis by installing double pane windows gives you the best starting energy efficiency at the best price. There are a lot of additions you can put on your windows to make them more efficient overall. The glass coating also helps prevent sun damage to furniture and flooring. Low-E coatings are microscopically thin, transparent particles that reduce the amount of heat and light that enters through the glass. The new standard of house windows are often offered with low-E coatings. Argon gas is a transparent and non-toxic gas that acts as a buffer to reduce transmission of thermal energy through the window glass. Moreover, double-pane windows are typically filled with argon gas instead of air. The hot and cold energy that wants to enter or escape your home will have a harder time doing this with multi-pane windows. The air pocket between panes of glass will slow down thermal transfer through the window. It's not the amount of layers that make the biggest difference it's the pockets of space between the glass. Glass alone offers no insulation value but double pane glass allows for some improvement. The one that makes double pane windows better than single pane is the insulation. There are quite a few window characteristics that play into their energy efficiency. Insulated Glass Options: Double, Triple, Quad Do Double Pane Windows Make a Difference? You see, double pane windows have two panes of glass and one layer of insulation while triple pane windows have three panes of glass and two layers of insulation.Įven though triple pane windows will make your home slightly more energy-efficient and soundproofed, most agree that the difference does not justify the additional cost over double pane windows, especially in temperate climates. If you compare double pane windows to triple pane windows, there are differences in insulation. That is where double pane glass comes in as a beneficial solution to maximizing your home's energy efficiency. However, to maximize the energy efficiency of your house, you want insulation to stop what temperature the glass does conduct. Single pane windows were good enough when glass windows were first made since glass is a poor conductor of heat. That means that the outside temperature has a lesser effect on your home's temperature since the insulation buffers it. Double pane windows have a layer of insulation in the form of air or gas between the panes of glass. The primary difference between the two is insulation. Double pane windows have two layers of glass fitted in the window. Single pane windows mean that they only have one layer of glass fitted within the window frame. So, how much of a difference do double pane windows make?įirst, it is important to understand what single pane and double pane windows are. Typically, homeowners compare double pane windows to single pane windows. Double pane windows can make quite a difference depending on what you compare them with.
