Double Glazing

As the heat of summer intensifies, there is a misconception that double glazing is only for keeping the cold out in winter. The truth? Double glazing in Sydney delivers powerful year-round performance – especially during the scorching hot months that lie ahead for may Sydneysiders. At Select Windows, your trusted Sydney window replacement specialists in energy-efficient windows and custom double glazing, this advanced technology is seamlessly integrated into, sliding doors, bi-fold doors, and more. Double glazing doesn’t just insulate – it actively blocks heat, in turn reduces energy bills, while transforming your home into a cool, comfortable retreat. With Sydney summers often exceeding 30°C and humidity spiking to 65%, NOW is a great time to upgrade your single-pane windows to double-glazed windows, that Sydney homeowners have come to rely on for lasting comfort.

How Double Glazing Works in Summer

Double glazing features two panes of glass with an insulating air or argon-filled gap, creating a thermal barrier. This stops hot outdoor air from entering, while keeping cool indoor air inside – perfect on hot summer days. Unlike single-pane windows that act like radiators, double-glazed windows maintain stable indoor temperatures, reducing reliance on air conditioning and preventing heat build-up.

With a low-E glass or low-emissivity coating, double-glazed windows reflect infrared heat and harsh UV rays, while allowing natural light in – ideal for bright, cool living spaces.
