What Are Energy Efficient Windows?

What-Are-Energy-Efficient-Windows

Windows can affect the energy efficiency of any home. During winter, the windows alone can increase the heating bill by as much as 20 percent! During summer, the sun warms the interior of the house through your windows.

This overworks the air conditioners as they pump air to regulate the temperature. Energy efficient windows are designed to save on energy while also saving the environment. These windows go a long way in reducing the carbon footprint of a house. This reduces greenhouse gas emissions. The following features on a window will boost your home’s energy efficiency and lower your bills:

Glass Coating

Energy efficient windows have a low-emissivity glass (Low-E glass) coating. This glass coating helps to block the harmful UV rays. This retains interior heat, especially during cold weather. There are several glazing options that homeowners can choose from too. Some of the most common are gas fills, tints and reflective coatings.

Spacer Systems

Energy efficient windows should be condensation free and thermally efficient. Various polymers and structural foams will insulate the windows better, hence increasing their efficiency. When looking at window spacer systems, go for the ones that have a low U-value. The lower the U-value, the more efficient the window.

Window Technology

Double and triple pane glass helps to block the UV rays. It is estimated that you can block up to 95% of UV rays with a triple pane energy efficient glass window. This window technology also goes a long way to prevent fading of furniture and fabric. Adding filling in the window spaces could also improve insulation. This further reduces heat transfer.

Benefits of Energy Efficient Windows

  • energy and cost savings
  • improved comfort
  • lower bills
  • increased light and view
  • reduced condensation
  • reduced fading of furniture, curtains, and flooring

Considerations for Energy Efficiency

Window Frames

Choosing the right window frame will determine your window’s energy efficiency. Each material has a different energy rating.

uPVC frames are easy to fashion and install. If you care for nature, you will find solace in the fact that they are recyclable.

Wooden frames are another alternative. Wood can sustain environmental impact, but it does require regular maintenance.

Steel or aluminum frames are a popular choice thanks to their versatility and looks. The frames are slim and can also recyclable.

Composite frames mash up plastic, aluminum, and an inner timber frame. These frames are weather proof and do not need regular maintenance.

Ventilation

Energy efficient windows are more airtight when compared to the original frames. As such, condensation can easily build up inside a house.

You need to assess your ventilation needs before buying replacement windows. Window frames with trickle vents are a good way to ramp up the ventilation.

Other Considerations

If you have old and inefficient windows, it is more cost effective to replace them than to improve their efficiency. The savings you make on heating and cooling costs, in the long run, will be worth the replacement costs.

Establish your efficiency needs and find out what will work best for your home in advance. An installation professional will explain to you the energy performance ratings. This will give you an understanding of what you need based on the climate and the design of your home.

Window technology now allows for smaller and less costly heating and cooling equipment.

Energy efficiency on windows also vary depending on your climate. The best windows for cold regions aren’t necessarily the best for hot areas.

Understanding your local climate is the key to choosing the perfect windows. If you are not sure of yourself, you can always consult with professionals. Seeking professional help ensures that you get exactly what you need when you need it.
