Energy-Efficient Windows For The Milwaukee Area
HomeSealed Installs Very Energy-Efficient Windows
& It Saves Homeowners Money Every Month For A Lifetime
A lot of homeowners don’t understand just how much money can leak out their windows every month in the form of wasted energy. Simply put, windows are the #1-way heating and cooling escapes your home.
If you make the right window replacement decision now, you will save yourself money each and every month for the life of your home. And, unfortunately, the reverse is also true: you’ll be reminded of a bad replacement windows decision every month when your energy bill arrives.
Of course, energy-efficient windows take on even more importance in a climate of often extreme temperatures that we are subject to in the Milwaukee area.
So, what do you need to know about energy-efficient windows?
Your Quick Guide To Energy Efficient Windows In Milwaukee
There are a few key ratings and qualities that you should understand:
Air-Sealed Rating (CFM)
At HomeSealed, we often talk about how our windows are 2,000% more airtight compared to the average competitor’s window. But you might wonder what the facts are behind that claim.
To understand why we say that, you first need to know that every window on the market is assigned an air-sealed rating based on independent lab testing. The rating is expressed in CFMs, or cubic feet of air per minute, which is really just a fancy scientific way to say how much air infiltration any given window allows.
The key point for homeowners is this: the lower the rating, the more air-tight a window is. And the more air-tight a window, the less drafty and more energy-efficient it is.
Here are the details and facts about specific CFM ratings. The worst air-seal rating a window can get and still legally be sold is .3 CFM. Homeowners should avoid any replacement window with a CFM that high – period.
The next step up is .2 CFM. That’s the rating of a window from one of our typical competitors – even some very well-known brands that are considered quality choices. From there, CFM ratings keep going all the way down to the very best rating of point ZERO one – a window actually can’t be rated at absolute zero, because the difference between .01 and actual zero is too small to be measured.
HomeSealed windows are rated .01. If you calculate the difference between a typical competitor window with a .2 CFM and a HomeSealed window with a .01 rating, that comes out to 2000% more air-tight. There is literally not a window in the world with a better air-sealed rating than our windows.
Besides CFM, there’s one other rating that is important to for understanding energy-efficiency, and that’s U-Value. This rating is especially important for our cold Wisconsin winters.
The simplest way to put it is this: the lower the U-Value, the more energy-efficient your windows.
Here’s why: a lower U-Value means a window that is more resistant to heat flow. And it’s important to minimize heat flow because the higher it is, the more energy and dollars are escaping out your windows.
So, what specific U-Value should you look for?
If you want to get through a Milwaukee area winter with lower energy costs, you want a MINIMUM of a .30 U-Factor, and we strongly recommend something in the .20 to .25 range.
A Terrible Way To Lower Your U-Value
We do want to warn homeowners about a way to lower U-Values that we strongly disagree with. Many replacement window companies will tell you they will sell you multiple coats of Low E to improve their U-Factor. Don’t get us wrong – Low E is good. But using too many coats to artificially lower a U-Factor is a very bad idea. It will make for darker replacement windows that are often less efficient because they block TOO much heat.
Always stick with a window that is manufactured with a great U-Value to begin with; that’s what will keep you comfortable without darkening your windows.
A Note About EnergyStar
We think having EnergyStar standards are a good starting place. At least homeowners are getting some independent standard to measure whether a window is of decent quality.
That said, we think some homeowners are lulled into thinking they are getting a very energy-efficient window just because it has the EnergyStar sticker. Our opinion is that should be the absolute minimum standard, and that in most cases homeowners should look for windows that far exceed EnergyStar standards.
