Double glazing refers to windows made with two glass panes separated by a small gap, which is filled with a heavy noble gas like argon. This design serves as a barrier, minimising the transfer of heat through the window. The result is enhanced insulation, effectively curbing heat loss from your home and boosting overall energy efficiency. Beyond temperature control, double glazing will also contribute to noise reduction, creating a more comfortable and peaceful indoor environment. The insulating properties of double glazing make it a practical investment if you’re seeking to enhance both comfort and energy savings in your home.
Double glazing effectively minimises heat loss by creating a barrier that slows down the transfer of heat through the window. The combination of two glass panes with argon gas between them works together to significantly reduce the heat transferred through your window. This not only contributes to maintaining a warmer interior during winter but also ensures a cooler environment in the summer. The result is twofold- lower energy bills and increased comfort throughout the year, making double glazing a practical and cost-effective solution for temperature regulation in your home.
Typically, double-glazing windows boast an average lifespan of 20 to 25 years, although many surpass this duration. With proper care and maintenance, such as regular cleaning of frames and glass, and careful inspection for signs of wear and tear, the longevity of double glazing can be extended. Taking these proactive measures not only ensures optimal performance but also contributes to energy efficiency.
The price of double glazing depends on a few things like the size and style of the window, the frame material, and the type of glass. Generally, for a regular-sized window, it can range from a few hundred to a few thousand pounds. Keep in mind that larger or fancier windows, or those made with high-end materials, might cost more. It’s also good to think about the long-term benefits, like saving on energy and increasing your home’s value, when considering the value of your investment.
Yes, we offer triple glazing as well as double glazing.
In short, yes. Triple glazing uses the same technology as double glazing, but more effectively, by adding an extra layer of glass and gas. The additional layer in triple glazing results in superior thermal efficiency, sound insulation, and condensation control, among other things.
U-value, a measure of heat loss through glass, demonstrates the improved efficiency of triple glazing. The lower the U-value, the better. Double glazed glass typically has a U-value around 1.2, while triple glazing achieves an impressive 0.8. This means that triple glazing reduces heat loss and gain by 33%. With triple glazing installed, your home will be warmer in the winter, and stay cooler in the summer.
While requiring more materials (and thus a higher cost), triple glazing’s long-term energy savings make it a very worthwhile investment, especially for UK homes.
