Getting an ideal window for your Columbus, Ohio home is all about finding an ideal balance of aesthetics and function. To find this a homeowner must navigate design and material options, and figure out what vital factors contribute to making an energy-efficient window. But you needn’t try to handle it all on your own. At APCO our team specializes in offering superior, top-class windows, and we want to help you understand what makes a great window great.
One of the five major factors that contributes to a window’s efficiency is air infiltration, and for now we would like to focus on that. How does infiltration impact efficiency, and what are you looking for in an infiltration resistant window? Follow along while we detail the basics.
In essence a window’s air infiltration score details how much air leakage occurs at the joints in the frame. Much of what impacts heat gain and loss in a home is attributed to this, and thus the rating plays an absolutely huge role in what constitutes an efficient window.
The air infiltration rating is expressed by a numerical value that shows the amount of air infiltration by cubic feet. It looks something like this: cfm/sqft=rating, or cubic feet per minute compared by square footage of the window equals rating. To keep this simple we’ll go with what ENERGY STAR® constitutes as a window that is acceptably infiltration resistant, which is a window that offers AL (Air Leakage) ratings of .30 or lower.
With an AL rating, the lower the number the better, with .20 being a more leak-resistant window than a .30 window, and so on. Absolute top-end windows can feature ratings as low as .10, but this is not only uncommon, but often less worth it than it might seem. The optimal option is finding the window that is the correct size for your needs that offers respectable ratings at a cost you can be happy with!
It’s very, very worth noting that the size of a window does factor into its air infiltration rating. Since the measurement of the window factors into the formula, a smaller window will almost always have a lower AL rating than a window of the same materials and level of quality. This can be very misleading when buying windows, and a few less scrupulous window manufacturers occasionally use this confusion to their advantage when selling.
There are a few important factors to consider when looking for a low leakage window, including:
