Double glazing window is a system of multiple glass panes separated by an insulating gas layer. Its basic function is to provide better sound and heat insulation without compromising on light transmission. The contemporary homeowners usually prefer double glazing solutions over conventional single-glazed windows and the majority of modern homes are built with these innovative glazing solutions.

Top Reasons to Replace Ordinary Windows with Double Glazing Windows


Homeowners usually opt for glazing window solutions as it provides them with a myriad of unique performance benefits. These innovative energy-efficient windows offer much more than simple insulation and augmented protection. The following are the top reasons why you need to replace conventional single-glazed windows with double glazing.

  • Enhanced Energy Efficiency


Double pane windows offer optimum heat insulation and serve as an energy-efficient design element. These windows prevent heat loss and help keep the indoors pleasantly warm in the cold days of winter. Restricting the escape of heat energy, the heaters work more efficiently with the use of double glazing systems.

  • Improved Security


Multiple layers of glass provide better impact resistance and protection than the conventional single-glazed windows. These windows are incredibly hard to break and the presence of a gas layer in between gives the system greater structural integrity. The majority of double glazing systems are designed with an extra layer of film that provides better privacy.

  • Eco-Friendly


These windows greatly contribute to the reduction of the overall carbon footprint as they restrict the escape of the warmth of the home. Minimizing the use of electronic appliances, the inclusion of double glazing windows makes the home eco-friendlier. These little design measures advocate a sense of environmental awareness and make viable contributions to protecting the atmosphere.

  • Better Heat & Sound Insulation

These windows serve as a sound barrier and restrict the ingress of unwanted outdoor noises. Their improved insulation characteristics make it an ideal window choice for homeowners who desire to create a secluded and serene indoor environment. Their heat and sound insulation function both ways and create a fine boundary line between the indoors and the outdoors.

Specifications of Double Glazing Windows

The technical specification of double glazing home windows focuses on parameters such as U-Value, Solar Heat Gain Coefficient (SHGC), Visible Transmittance (VT), and the thickness of the glass. All these parameters depend on window type, glass, and type of frames. The modernistic windows have frames made specifically to help reduce the U Value and Solar Heat Gain Coefficients. It is essential for homeowners to consider these specifications when selecting the double glazing solution for their homes.

  • U Value

U-value is the measure of heat transfer through a building element and lower U values indicate low heat transfer capabilities and better insulative properties. The U value of conventional single-glazed windows ranges around 5 and 6 and the value of Low-E windows is around 4 and 5. These values are relatively bad as compared to double glazing solution that significantly restricts heat transfer and has a U value in the range of 1.5 to 3.5.

  • Solar Heat Gain Coefficient (SGHC)

Solar Heat Gain Coefficient (SGHC) is the measure of heat gain from the windows in the summer season. Windows with lower SGHC values are optimum for warm and hot areas as it helps keep the interior cool with minimal heat gain. The SGHC values usually lie in the range of 0.3 – 0.9. Double glazing windows have a value in the range of 0.6 – 0.7.

  • Visible Transmittance (VT)

Visible Transmittance (VT) is the measure of natural daylight that windows can successfully transmit during the daytime. Higher VT values are preferred by homeowners as it allows sunlight to properly illuminate the interior space and minimize the use of electricity. The value ranges from 0.3 to 0.85.

Benefits of Double Glazing Windows

The benefits of the contemporary window solutions exceed beyond heat insulation and energy consumption. These windows are designed to provide homeowners with improved protection and better security. Their role in improving the overall comfort level in the home by insulating sound and heat energy cannot be undermined. Consequently, the simple inclusion of modern window solutions has a drastic impact on the overall greenhouse gas emission and energy consumption.

Double glazing windows also protect the environment by reducing noise pollution. Other benefits of these windows include the reduction of condensation on the inside panes of windows that often obstruct the view and translucency. These windows also have lower running costs and their augmented strength and durability make them an ideal long-term solution for contemporary homes. These windows are worth the extra cost and serve as an economical solution in the long run and safeguard and protect the environment for the generations of today and tomorrow.
