2 Ways Our Double Glazing Can Reduce Heat Loss In Your Home

14 Jul 2023

According to sources, 18% of heat is lost through windows and doors in British homes and heat is lost twice as fast through single-pane windows than through double glazed windows. In our previous articles, we raved about the fantastic benefits of double glazing. One of those benefits is that it can reduce heat loss. This can happen in two different ways. In this article, we will discuss how double glazing works and the two ways in which double glazing can reduce heat loss in your home.

1) The Reason Behind The Spacer 

To understand the first way, you need to understand the structure. Double glazing consists of two panes of glass with a small gap, called the spacer, between them. The spacer is usually filled with air or argon gas, which acts as a heat insulator. The wider the spacer, the higher the insulating properties, but also the cost. This insulating ability is due to the fact that both air and argon gas are poor conductors of heat. In other words, the spacer makes it difficult for heat to pass through the two panes of glass. As a result, the heat is trapped, keeping your home more energy-efficient and staying longer at a comfortable temperature. 

2)  Low-Emissivity Coating

Double glazing can also reduce heat loss by reflecting heat back into your home. This is achieved by a special low-emissivity coating, or low-e coating found on the inner side of modern window glass. It’s worth noting, this low-e coating isn’t typically featured on older double glazing. It is usually invisible to the naked eye and it doesn’t affect the amount of daylight that enters your home. When heat from the sun shines on low-e coated, double glazed windows, this coating absorbs the heat and reflects the heat back into your home. 

Coatings differ from manufacturer to manufacturer, as some are designed to reflect a high amount of heat in the winter. In contrast, others are designed to minimise the amount of heat that enters the house, keeping your rooms cooler in the summer. The type of coating greatly depends on the climate and your specific needs.
