In recent years, double-glazed windows, also known as insulated windows, have become a popular choice for premium urban residences. These contemporary windows contain panes of glass and are available framed in materials like aluminium and uPVC. The space between the two glass panes is filled with inert gases like xenon, argon or krypton to form an airtight seal and an insulating barrier between the interior and exterior of the building. If you are planning to install new windows or replace the old ones, our guide will help you decide whether double-glazed windows are the way to go.

• Pro: Improves energy efficiency

Double glazing significantly reduces the amount of heat that enters or exits the home and the airtight seal ensures effective thermal insulation. So, in hot climates, double glazing reduces the heat gain within the interiors. This improves the overall performance of the air-conditioner and reduces power consumption of a home, thus ensuring good savings on electricity bills and a reduced carbon footprint.'

• Pro: Ensures soundproofing

Another advantage of double-glazed windows is that they work as an effective acoustic barrier that significantly reduces noise pollution from the outdoors and creates soundproof interiors. These windows are highly suitable for homes that are close to noisy main roads, schools, airports and so on.

• Pro: Good security

Double-glazed windows are much stronger than single-pane windows, which makes them tough to break. Additionally, these windows are sturdy and less likely to rattle in the wind or due to vibrations caused by heavy traffic. One can also incorporate modern security locking systems into the double-glazed window units.

• Pro: Prevents fading from UV rays

Another plus is that double glazing prevents UV rays from making their way into the interiors and they protect the furnishings, carpets and paintings from fading.
 

• Con: Very expensive

Double-glazed window are comparatively much more expensive than single-glazed windows.

• Con: Cannot be repaired

The main drawback of double-glazed windows is that they cannot be repaired. Make sure that the double glass panes are airtight and properly sealed, otherwise condensation may appear between both the panes of glass. In case of any damage, the whole window will have to be completely replaced.

• Con: Not suitable for traditional homes

One by-product of bringing in double-glazed windows is that they give the home a modern look. As a result, these windows can mismatch and clash with homes that have a traditional home style or decor.
