How Windows Improve Indoor Air Quality

Your windows are a key part of improving the air quality inside your home. Good operable windows reduce humidity and stop mold growth by letting in a lot of fresh air. In this blog post, Renewal by Andersen® of Montana talks about how windows can improve your home’s indoor air quality.

Improve Indoor Air Quality

How Can Indoor Air Be Unhealthy?

Due to factors including factory exhaust, wildfire smoke and car emissions from traffic, outdoor air can become contaminated and harmful. However, indoor air can get even more polluted than that.

Sources of indoor air contaminants range from dust and pet dander, to building materials (paint, sealants, flooring, insulation) and household objects (electronics, appliances, toys, furniture, carpets and air fresheners). Indoor air can also be affected because of cooking fumes and chemical cleaners.

How Window Replacement Can Improve Indoor Air Quality

Fortunately, you can help minimize particulate matter that can affect the air you and your family members breathe with the help of windows. Here’s what they can do for you:

  • Provide natural ventilation. At home, dust, pet dander and other airborne contaminants tend to linger, causing some individuals to develop allergies and other respiratory disorders. Windows promote natural ventilation, which helps remove airborne contaminants from your living spaces. Simply open your windows for at least 15 minutes daily to replenish the air in your home.
  • Maintain stable indoor moisture levels. Indoor humidity can affect air quality and create a muggy, uncomfortable environment. Moisture makes the air denser, making it more challenging to breathe. Again, good ventilation provided by open windows aids in mitigating this problem, with the right window design being even more effective. Double-hung, casement and sliding windows help facilitate natural ventilation by exchanging moist, heated air for cool, fresh air.
  • Lower VOC emissions. How well your windows cut down on volatile organic compounds depends on the materials from which they are made. This won’t be much of a problem if you choose Renewal by Andersen windows. They are made of Fibrex®, an innovative composite material with at least 40% recycled wood fibers by weight. Investing in these replacement windows not only enhances your home’s indoor air quality but also helps in promoting a healthier and safer environment.

"I highly recommend Renewal by Andersen. We were treated well and everything went smoothly from start to finish. The company kept in contact with me before, during, and after the installation and let me know what to expect. I'm in love with my new windows! I will be using this company again when we refinish our basement. "
