Lower power bills

I want to reduce my power bills and maintain a consistent temperature year round.

How can double glazing reduce my power bills?

  • Retrofitting is a smart investment tailored to your home. With the right Low E in your double glazing, you can maintain a more consistent temperature year round.

  • Choosing Low E with your double glazing solution provides the following key benefits that lead to less energy consumption, and reduced monthly power bills helping the environment.

    • Warmer home in winter - our Xtreme™ Low E glass gives your home up to 79% better heat retention compared to single glazing, keeping the heat inside and the cold outside - meaning less need for heaters and heat pumps.

    • A cooler home in summer - when you choose a Low E glass with solar control properties, it minimises solar heat gain from the sun coming through your windows. This reduces the potential of overheating in summer while providing insulation to keep your home warm in winter. With less need for cooling appliances like air conditioners, you’ll save on power bills and reduce your environmental impact. - Check out our solar control range here.

    • Reduced condensation. Condensation is that “crying look” that single glazed windows get. This is a serious problem as it causes mould and mildew, and damages your family's health. Using Low E glass with proper ventilation provides effective thermal insulation, keeping warmth inside and creating a dry, comfortable home. This reduces the likelihood of condensation on windows and minimises the need for dehumidifiers—helping lower your power bills.

    • Better resale value of your home. Having a more thermally efficient home can improve the feel of the home and reduce its energy usage decreasing power bills.

How does Low E work?

  • Low E glass (short for Low Emissivity glass), is very energy efficient with a special coating that lets in natural light while retaining heat inside and alleviating unwanted solar heat to help maintain indoor comfort levels.

  • Our selection of Low E glass is tailored to New Zealand conditions, offering a variety of performance benefits such as reducing heat loss, solar control, natural light levels, noise, fading and glare reduction. We have a range to cater to your specific priorities.
