WINDOWS AND YOU

So your house probably isn’t just some seamless block with a roof over it. There are likely several seams and openings — ways in and out of the home. Your door is usually the main one, but there are others too, like back doors and windows.

If you’re trying to improve energy efficiency, your doors and windows play a significant role in your overall energy use. Insulation is important, but doors and windows create points where that insulation can break down because they are physical openings in the building envelope.

This is where High-Performance Windows become essential.

So how do you solve that problem? How do you make sure your windows aren’t liabilities in your journey toward net zero energy performance?

Install awnings

Unless your windows are tinted, they’ll let in a lot of heat. Clear glass doesn’t do much to stop solar radiation from entering a space. So what can you do to reduce overheating?

It’s fairly simple — install awnings. Awnings can block a significant amount of solar heat gain before it reaches the glass. This helps reduce indoor temperatures and keeps rooms cooler without relying heavily on air-conditioning.

Double paned windows

Clear glass on its own doesn’t provide much thermal protection. That’s the challenge with transparency — heat and energy pass through easily, warming up interior spaces and increasing cooling demand.

This often leads to higher air-conditioning use, which increases energy consumption.

Double paned windows help solve this. They consist of two panes of glass with an inert gas like argon or krypton between them, reducing heat transfer and improving thermal performance. This helps maintain indoor comfort while lowering energy use.

For even greater performance, triple glazing adds another layer of glass and insulation gap, further reducing heat gain and heat loss.

Curtains or blinds

Another simple and effective solution is internal shading. Curtains or blinds can significantly reduce heat gain when closed during peak sun exposure.

If you don’t already have them, installing properly fitted curtains or blinds is a cost-effective way to improve comfort and reduce overheating.

Up high and open

Heat rises, which means ventilation strategy matters. If warm air builds up inside a room, high-level windows can help release it naturally.

Opening windows positioned higher in a space allows hot air to escape, improving airflow without mechanical cooling.

There are many ways to improve the energy efficiency of a home, and many of them come down to how the building is detailed and how its components perform together.

Windows serve multiple functions — they bring in light, provide ventilation, and connect us to the outdoors. But they can also be a major source of heat gain or loss.
