Helpful Hints for Installing Double-Glazed Windows in Your Home

Vast windows that stretch across the walls of your home let daylight stream inside for a more welcoming vibe. However, single-pane windows can be problematic as they let the warmth flow inside in the summer and escape outside in the winter. Glass is much easier for heat to move through than walls, which are thicker and often filled with insulation. One solution to this is double glazing. Here are several hints to help you install the best units for your home.

Temperature Regulation

A double-glazed unit consists of two glass panes instead of one, with a sealed pocket of air or gas in between. It's difficult for heat to pass through the gap, so these windows will keep your home more comfortable in both summer and winter. The wider the gap between the two panes, the more effectively the windows will hinder heat transfer. Also, argon gas will be harder for the warmth to pass through than air.

Energy-Efficient Building

With double-glazed windows, your home will be more energy efficient, reducing your reliance on air conditioning and heating. Thus, you'll save on ongoing energy costs. A greener house may also appeal to prospective buyers if you're selling, as many people are interested in reducing their carbon footprint. The new windows will usually last for many years, offering a long-term investment in the building.


When choosing which double glazed windows to install, consider the frames and how efficient they are. Aluminium frames let the heat move from one side to the other as this metal is a good heat conductor. The sun will warm up the frame outside, then transfer to the inside and radiate into the room, which is not desirable in the summer. To avoid this, install aluminium windows with a thermal break. These models are fitted with a different material in the middle to block the heat flow. Other window frame materials, such as timber and PVC, are relatively efficient as they don't allow heat flow easily.

Efficient Glass

You can also install energy-efficient panes, such as Low-E glass, within the unit. These panes have a thin film that reflects heat away. Depending on what you want to achieve, you can install the Low-E glass on the inner or outer pane of a double-glazed unit. For example, your priority may be to deflect heat back into the room if you live in a cool climate. Or else, you might live in a hot region, and you can install Low-E glass to deflect the solar radiation away from your home.
