Air leakage doesn’t only happen due to problems with old windows. Sometimes even new windows can have this issue. That’s why you have to be careful when hiring a window company to carry out an installation job.
To learn more about air leakage, Renewal by Andersen of Denver discusses a few basic things you should know. We also share some tips on how you can detect air leaks.
What Is Air Leakage?
As mentioned earlier, new windows can cause draft problems depending on a variety of factors such as the quality of installation. However, this doesn’t always involve significant amounts of air being leaked into your home.
Typically, the air that passes through a window assembly is measured on a scale of 0.1 to 0.3 (with 0.1 being the least amount of air that passes through a window) prior to installation. This measurement is called air leakage or air infiltration. What window installers do is they make sure to keep the air leakage at that specific amount to avoid drafts.
How to Check for Air Leakage
When shopping for replacement windows, ask the company about the air infiltration ratings of their products. Windows with ratings below 0.3 are considered energy-efficient by ENERGY STAR® and NFRC (National Fenestration Ratings Council), so you should look for these.
To detect air leaks around windows, you can try the incense stick method. Simply hold a lit incense stick near window frames and observe smoke movement. Note the areas where caulk, sealant and weatherstripping may be needed.
