With the energy price rises affecting so many households, property owners are looking for ways to conserve energy in the home. It’s a good time to review how your home can become more energy efficient, from protecting windows in bad weather to ensuring you have the best glazing.

Here’s everything you need to know.

What are the benefits of energy-efficient windows?

Windows are some of the most common areas of a property where warm and cool air escapes, wasting energy in the home. If windows aren’t good at keeping in warmth, homeowners may turn up their heating, leading to higher bills. New energy-efficient windows can help you to reduce your energy costs and carbon footprint.

If you still have single glazed windows, it may be time to look at other options, including new double or triple glazed windows or interior secondary glazing units for listed buildings.

The additional glass present in all these upgrades improves thermal efficiency in the home, containing a non-toxic gas between the panes to insulate the inside of the windows. Modern windows also have airtight seals to stop heat from escaping from this once vulnerable spot.

Can new windows help you save energy?

What type of window glass is best?

Energy-efficient windows come in a range of materials, such as uPVC and aluminium, so discuss with your supplier which is best for reducing heat loss. While aluminium frames are made from metal, most contain a thermal break to reduce heat loss. They may also recommend some of the best glass products for the panes, including low-E glass.

Low-E glass stands for ‘low emissivity’, resulting from a transparent, microscopically thin layer of metal oxide used on one of the internal glass panes. This specialist coating reflects heat back into the room without reducing the amount of sunlight coming in through the window.

How energy saving are new windows?

When you first start looking at new windows, you may see references to different benefits available, such as u-values, but what does this mean? Well, a u-value is a measure of how much heat loss the glass allows, so the lower, the better. Make sure you check this value for any new doors you’re considering too.

You may also see the window’s WER score – its Window Energy Rating. This tells you how energy-efficient the overall product is (rather than individual components such as the glass or frame), with A++ having the best performance rating.

You should also ask your supplier about any other window features available that save energy, including non-metal pane spacers. Many windows use these around the inside edges to keep the glass panes apart, but the most energy-efficient products will use little or no metal for them.
