Why double-glazed windows?

When it comes to windows, double-paned windows are becoming increasingly prevalent worldwide. Any window and door manufacturer supplying FRP doors or double windows worldwide would attest to this. Several reasons have contributed to the rising demand for double glazed window service. The explanations behind this are as follows:

Double-glazed windows are a great way to save energy while also reducing noise. The air gap between the two panes provides an additional layer of insulation. In the winter, this improved thermal resistance reduces heat loss and keeps the residence at a more comfortable temperature. Double glass has the reverse effect in the summer, preventing unnecessary heat from entering the home. This added insulation decreases your reliance on artificial heating and cooling, resulting in cheaper long-term energy costs.

The degree of the glass affects your comfort while you’re close to it. The exterior temperature is less likely to flow through the double glass, keeping the internal pane at a comfortable temperature. Condensation, which may contribute to mould formation, is decreased by two.

Sealed double glazing efficiently reduces moderate to high-frequency noise, such as human speech. A variation in window thickness between the interior and exterior panes will increase sound suppression. Double-glazed windows are regarded to be a safer alternative than single-pane windows. Two pieces of glass are harder to break than one, and you may choose toughened or laminated glass for further security.

What to Look Out For

Millimetres measure the distance between the panes – 6 to 20 mm is the usual distance between panes. A minimum separation of 12mm is recommended for best thermal performance. For acoustic control and the elimination of low-frequency noises such as traffic and aeroplanes, a minimum air gap of 150mm or more is advised. Such significant gaps enable convection between the panes, reducing insulating efficacy.

What lies in the middle part?

Because the space between the panes of double-glazed windows is sealed, it acts as an insulator and keeps cold air out of your home. The thermal and acoustic performance of this space increases as gas fills it. Argon, which has a low conductivity and improves insulation, is one of the most often utilised gases.

A spacer, a steel or polymer strip that separates two panes of glass, is provided in double-glazed units. Desiccants are commonly used in spacers to remove moisture from the air gap.

The type of glass that is used

Several glass types, such as Low-E or laminated, can be used in double glazing units for effective energy and noise control. Low-e glass will further reduce heat loss, while bigger laminated panes will disrupt sound waves for improved acoustics.

Typical problems

Windows must be seen as a whole. The frame material you choose to complement your glass might help or detract from its energy efficiency in some cases. Standard aluminium window frames quickly conduct heat and cold, and if they are not thermally enhanced, the benefits of expensive double glazing may be negated.

The type of spacer used and how the cavity is sealed are critical considerations. Because condensation will develop on cold surfaces if the component is not adequately packed or the spacer does not include enough desiccant, customers must rely on double glazed window service. So, this article gave you information on why to choose double-glazed windows.
