Glass can enhance the way your home looks and feels, but it also adds to the warmth and thermal efficiency of your home.
It’s a good idea to work through your options to find the right glass for your home. With options to reduce the fading, reduce heat loss and increase year-round comfort, your decisions can have a significant impact on the performance of your glazing.
- Choose a high-performance glass option to ensure your Klima Series window systems are rated a maximum 6 energy stars under WEERS (Window Energy Efficiency Rating System).
- Discuss with your manufacturer the orientation and shading of your home, the climate and noise around where you live.
There are a number of performance glass options to suit most requirements. Here is a quick overview of the most popular options to consider for double-glazing.
Low-E (the ‘e’ stands for emissivity) glass is a virtually invisible coating incorporated into your double glazing, improving the level of insulation in your home. The Low-E coating is applied to the inside surface of the exterior glass pane, protecting it from the elements.
A thermal spacer reduces heat transfer through the glass edge and improves the seal that is key to genuine double-glazing. A thermal spacer holds the two glass panes of your double-glazed windows and doors apart and creates a seal to hold in a gas fill. This keeps warm and cold areas separated, reducing heat loss around the outside of your glazing.
Inert gases such as argon can be used as an insulator in double-glazing to create an additional barrier to heat loss and heat absorption, improving thermal performance. The efficiency of a gas fill is enhanced when paired with a thermal spacer.
What does NZ-designed Low-E do?
Blocks excessive heat
Low-E lets the sun’s visible light pass through but reflects the ‘sunheat’ back out again. With less heat entering your home, there’s less need for air-conditioning to keep it cool.
Low-E helps protect furnishings in the home from fading by reducing the amount of damaging light that enters through the glass.
Low-E reflects the warm air in the home back into the house rather than escaping through the glass. This reduces the energy needed to keep the home warm in cooler months.
