What You Need to Know Before You Purchase a New Window

With over 50 years of experience, it’s safe to say Empire Windows knows a thing or two about windows. And speaking from experience, we know that there are always a few things to take into consideration when it comes to purchasing replacement windows.


Whether you have experience purchasing replacement windows before or not, price alone should never be the sole deciding factor when it comes to the final decision. While you think quality may be sacrificed by quantity, sometimes that is true, but that’s not always the case. So before you buy new windows, be sure to check out other things such as ratings, glass, and air filtration.


Ratings. True performance ratings are important for a window that you’re interested in purchasing. If a window is performing badly, it won’t matter whether it’s the cheapest or most-expensive window on the market. It just won’t serve a purpose for your needs. There are two websites that are non-profit and can give homeowners great insight into window performances. These websites include and Be sure to visit these sites for an in-depth review of a window’s performance before you make a decision.


The glass that makes up your window is an important part of the window as well. While you may think glass is just glass, that’s not the case when it comes to windows. It’s important to remember that when it comes to glass, a low U-value is important. The lower the U-value is, the better the window is at preventing heat from leaking out. It’s recommended that you only purchase a window with a U-value of .30 or less.


While many homeowners may not know what a DP rating is, it’s also known as a design pressure rating and it’s important to recognize that before purchasing a window. You should make sure your new window has a DP rating of 40 or higher. That rating shows that your window is stronger, better constructed and will last longer against rain and wind conditions.


And last, but certainly not least, air infiltration is another important factor when it comes to purchasing a new or replacement window. We strongly believe you should only choose a window with an air filtration of 0.07 or lower. This shows that your windows can sustain high winds and will be less susceptible if there are storms and inclement weather that causes high winds.
