Many Atlanta replacement window manufacturers, and their dealers, understand that you probably think that if you put a new replacement window into your home, and know that it was installed properly, you truly believe that you have taken care of drafts. As we learned previously, that, unfortunately, couldn't be farther from the truth.
So, how can you cut through all the sales lingo, and know for yourself. There are three things you personally can look for. First, ask the window representative to show you the NFRC sticker. As we discussed earlier, although they are well within their rights not to, if they don't publish that fourth number on the sticker (Air Leakage), there's probably a reason. Secondly, perform the "sash slop" test. With the lock (or locks) on the double hung window sample locked, grab either lift rail (top or bottom) and try to move the sashes. If there is movement in the sashes, you can be sure that air can infiltrate. By the way, the typical rehearsed response for this "slop" is "The window is made of vinyl, which expands and contracts, so we have to allow for that movement." The reality is that the mainframe is made of vinyl as well, but it has no movement. The third way to tell for yourself is to look at the weatherstripping. The most airtight products are going to have three pieces at every point of contact. Two pieces can indicate a product that has a significantly higher air leakage rate.
There can be lots of confusion about who has the best frame, or the best glass. When it comes to replacement windows in Atlanta, air leakage is the great un-equalizer, as those other two are meaningless if the window leaks air like a sieve.
