If you’re looking for new windows, you’ve likely heard a professional throw the term “air leakage” around. For those who are unaware, the air leakage rating is a measurement that helps determine how much air can pass through your window. The lower this rating is, the better your window performs.
Here, Renewal by Andersen® reveals why it’s important to understand window air leakage.
Why the Rating is Important?
Some homeowners are likely confused as to why their double-hung windows still have air leakage and the short answer is that it can’t be prevented. But you may be surprised to learn that this rating isn’t exactly required and therefore, some window companies tend to leave it out. This, however, is a red flag to look out for as you’ll still want to know the air leakage rating of the window you’re going to buy. The air leakage ratings of windows range from 0.1 to 0.3, with 0.1 being the most energy-efficient.
How to Check and Fix Air Leakage
If you suspect that your windows are having an air leakage issue, there is a way to completely confirm this. To do so, simply light an incense stick. Hold it near your windows where drafts may sneak in. If the smoke starts to swirl and escape, then it means you have an air leakage problem. If you’re looking to reinforce your new windows’ defense against air leakage, on the other hand, you can have your professionals replace the old weatherstripping with bronze or adhesive-backed EPDM rubber strips.
