Argon gas & Low-E glass?

What are the benefits of Argon Gas in windows and does a Low-E glass make a window energy efficient?

Double or triple-pane windows can be filled with argon gas to help insulate a room and minimize the transfer of heat through the window. It is a colourless, odourless gas and not harmful in any way if leaking should occur.

How does argon gas work?

Argon gas is denser than air, adding it to the captive air in double-pane or triple pane windows, it improves the thermal insulation efficiency. Used in conjunction with a special low-E (short for low emissivity) glass coating, argon gas windows bring the temperature of the window closer to room temperature. This process ultimately eliminates drafts & condensation, that occur when differing temperatures meet.While injecting argon into double-pane windows can be initially more expensive than cheaper, single-pane windows, the long-term benefits of energy efficiency are priceless. With more stringent energy codes being imposed in recent years, higher efficiency standards must be met when new windows are installed. If you’re considering window replacement or looking into house renovations, just remember that installing argon gas-filled windows can help improve your energy efficiency and lower your home energy costs.

What is a Low-E Window and What Makes it Energy Efficient?

Low-E, or low-emissivity, glass was created to minimize the amount of infrared and ultraviolet light that comes through your glass, without minimizing the amount of light that enters your home. Low-E glass windows have a microscopically thin coating that is transparent and reflects heat. The coating is even thinner than human hair!

The Low-E coatings keep the temperature in your home consistent by reflecting the interior temperatures back inside.

2 types of Low-E glass are available on the market!

If you live in an extremely cold climate, like Europe or some States in the US or Canada, the hard-coat Low-E glass may be an option for you, because it allows some of the sun’s short-wave infrared energy to pass through the glass. This helps to heat your home in the winter and allows the glass to reflect the interior long-wave heat energy back inside.

However, if you live in a moderate climate, like New Zealand, the soft-coat Low-E glass is best, since it offers better UV protection and has a better overall R-value. The soft-coat Low-E coating also reflects the warm and cool air back into your room instead of allowing it to leak outside.

When you’re trying to decide which window style, size and design is best for your home, it’s also very important to consider which type of glass would work best. Low-E coatings play a pivotal role in the performance of your windows, can save you money on energy costs and can drastically reduce fading to furniture and décor by blocking UV rays. Megrame has a standard Low-E Coating in their double or triple glazed units.
