Guide to Double Glazing

Double glazed units are made by filling a space between two pieces of glass with air or gas, creating the most energy efficient windows and doors available.

Over the years, aspirational design has become synonymous with energy efficiency. This is partly due to increased federal energy legislation and an uptick in climate-conscious consumers. Besides, energy efficiency isn’t just about reducing carbon emissions; it can also trim your energy costs and make your home more comfortable.

Double glazed windows and doors are a clever way to blend energy efficiency with your aesthetic. They play a big part in maintaining a comfortable indoor temperature year-round, and they can also help to improve insulation and reduce your carbon footprint and energy consumption. In fact, double glazed windows can decrease your home’s heat loss or gain by almost 30%.

This increased efficiency is achieved by a small, vacuumed air pocket. The space between the two glass sheets creates an insulated barrier, restricting the heat flow between indoors and out, ensuring your house stays warmer in winter and cooler in summer. Higher efficiency means that you’ll rely less on artificial heating and cooling, in turn reducing your energy costs.

Condensation happens when an interior of a room is warm and has a relative high humidity, and the surface of a window is cooler, causing water droplets in the air to stick to the glass. This can lead to mildew and mould, which can damage timber frames, architraves, or flooring. Double glazing is a great preventative solution to condensation because the internal glass pane will be closer to room temperature, meaning condensation is less likely to appear on the window.

For those that live in bustling city environments, constant noise can become a nuisance. Taking steps to reduce noise pollution can promote healthier sleep, lower stress levels and improve our ability to focus. While double glazed windows and doors aren’t entirely soundproof, installing them can have a significant impact on the amount of ambient noise that makes it into your home. The space between the two sheets of glass works to dampen incoming soundwaves, and also the combination of different glass thicknesses within a double glazed unit can make the inside of your home much quieter.

It's not always about the noise coming in. In spaces like a home theatre fitted with surround sound, it’s just as important to limit noise leaking out. Double glazed glass has the dual-action quality of limiting outgoing soundwaves - ensuring you can enjoy uncompromised sound quality without disturbing your neighbours.
