The Many Ways Windows Can Affect Indoor Air Quality

The Many Ways Windows Can Affect Indoor Air Quality

February 25, 2019

Improved indoor air quality is one of the advantages of buying better window systems. If you don’t understand how they can keep the air your family breathes clean and healthy, let Renewal by Andersen® of Milwaukee explain further.

Lead Air Pollution

If your current windows were manufactured before 1978, they may contain lead-based paint. This heavy metal was added to a finishing substance for better durability, stronger moisture resistance and faster drying time.

Lead, however, was found to be toxic. Exposure to lead can affect cognitive functions, cause behavioral problems and decrease IQ. Lead poisoning can also result in acute health conditions, including paralysis, anemia and vomiting.

Lead paint is only detrimental to human health when it begins to chip, turn into dust particles and is inhaled. Removing fixtures with lead paint requires specialized skills and tools to rid your house of this hazard effectively.


Any experienced windows contractor, like Renewal by Andersen of Milwaukee, would agree that proper ventilation is key to good indoor air quality. Usually, inside air is less healthy than outside, so it’s best to have a means of ventilation to get rid of invisible, odor-less pollutants.

Operating windows, such as casement, sliding and double-hung units, are excellent ventilators. Their efficiency, of course, depends on their location and size, but they can purify the air your family breathes naturally.

Furthermore, opening windows will keep your inside air dry by expelling high levels of moisture caused by excessive indoor humidity. This phenomenon allows mold to thrive, so installing operating windows in every room matters to discourage it from proliferating.


It refers to the process of releasing toxins through evaporation from construction elements. Although all building materials emit chemicals over time, products from a recipient of the Scientific Certification Systems Indoor Advantage Gold™ certification are your safest bets.

Renewal by Andersen of Milwaukee and Andersen Corporation, our parent company, are the only window brands to earn this coveted designation. In other words, our doors and windows are responsibly manufactured and meet the strictest indoor air emission standard in the United States.

Hear From Our Customers

This was a great crew to work with. Both the original install manager we worked with (Jay) and the install team (Daniel, Mason, Tony, Ethan, and Jose). Everyone was very professional and knowledgable. They answered all my questions and the end result on the house is great. In 3 days they replaced an old bay window with a new bay window, a set of french doors on the patio with a sliding patio door, and our old front door with a new front door and storm door.

I cant express how happy we are with choosing Andersen for our window installation. Our sales representative was knowledgeable with product and answered any questions we had without hesitation. I did also fill out a survey that was sent in an email, but sadly I failed to personally name the two gentlemen that performed the actual installation. Barrett and Francisco were our guys, and let me tell you, they were outstanding!!! They did Excellent work and were professional as well as efficient and made this a smooth, none evasive process for us. I strongly recommend this company and these installers to anyone in need of windows!!! My husband and I could not be more pleased we chose Andersen for replacing our windows!!!

Jason and Brett did an awesome job installing our doors. We had separate installers a month earlier for our windows who also did a fantastic job. They were all very professional and cleaned up almost better than the area looked before the installation! Since these were both jobs that took more than one day the installers were great at keeping us informed on the status of where the project was at along the way.
