Energy-Efficient Windows

In this day and age, it’s becoming more and more important to think about how efficient your home is. Not only for environmental reasons, but for financial reasons also. One of the most effective, and often overlooked, methods of keeping your house energy efficient is the installation of energy-saving windows.

Windows are the primary source of heat escaping from your house. If you don’t already have double glazing, then getting these type of windows is the essential start. You’ll be surprised the amount of people who think that double glazing is only for reduced noise entering the house.

Double glazing works by instead of having just one pane of glass, double glazed windows have two panes of glass separated by a void usually filled with a halogen gas such as argon or neon. These windows will reduce the amount of heat lost through your windows in the winter.

When choosing the frame material for your windows, there are a few options to suit your requirements.

uPVC – This plastic material is becoming more and more popular with both installers and customers due to its efficiency rating. uPVC is also durable and recyclable which makes it popular.

Wood – Wooden frames have less of an environmental impact but require periodic maintenance. They are most popular when installing windows into old buildings where a wooden frame is already present.

As British summers are tending to get hotter, the popularity of conservatories has risen over the last decade. Conservatories, if not properly sealed, can lose tremendous amounts of heat when not in use during the winter. Argon insulation is recommended by Allerton Windows, to keep heat in during the winter months.
