With many of us looking to reduce our carbon footprint and minimise energy wastage it may come as a surprise that great energy savings can be made by replacing windows. You might think double glazed windows offer this anyway but unless you’re in a new build it’s highly likely your energy efficiency can be improved by new technology offered in glazing.
Energy efficient glazing helps reduce your carbon footprint and your energy bills. The term is used to describe the double glazing or triple glazing use in modern homes. Double glazed windows (or triple glazing) works by having an insulating gap between the panes of glass that forms a barrier to keep the heat in. This gap is sometimes filled with gas.
New energy efficient windows also incorporate low-emissivity glass to reflect the heat back into the room. Low-E glass works by having an invisible coating of metal oxide on one of the panes that let in light and heat but reduces the amount of heat that can escape out.
Low-E glass makes windows highly thermally insulating, improving your energy consumption and thus reducing your heating bills. Many older double glazed units do not contain low-emissivity glass are not energy efficient. Another consideration is the frames of the window themselves, older frames can mean air leakage rates are higher.
When selecting new windows look at the energy performance ratings. The Government Energy Ratings scheme rates windows on a scale from A+ to G, A+ is the most energy-efficient windows.
Visually you may also benefit from replacement windows, giving a fresh look to your home and investment in replacement windows can improve the value of your home in addition to cutting your monthly bills and decreasing the size of your carbon footprint.
