Beware of the $189 window

cheap replacement window affordable window install kansas city$189 Window Companies in Kansas City…Beware! You’ve heard the commercials touting windows for $189. Unfortunately, we have found that this is really just a marketing ploy to get customers to call. Once you start dealing with these companies, you find that the $189 price they promise covers very little and every feature you want is an “add on” which raises the price of the window. Most companies just want to sell you one window…their window. They will tell you how great it is and why it’s worth what they charge – duh. That’s because they want you to buy their window! We call this the win”duh” factor of Window Replacement. Don’t fall victim to the win”duh” factor.

At Cornerstone Home Improvements, our job is not to sell you a specific window or sell you a window based solely on price. You’ll never see a “$189 Window Special” here. Our job is to educate you about windows – all kinds of windows – so you can find the best window for your home and your budget. At Cornerstone, we’re in your corner. Because we don’t work for a single manufacturer, we give you an unbiased opinion and straight facts to help you make the best decision. At Cornerstone, we carry dozens of brands. We’ll show you different options and let you decide after comparing all the facts.

One thing you won’t find at Cornerstone is poorly insulated windows. A poorly insulated window can attribute to 25 percent of a building’s heating and cooling loads. As a homeowner, it is just as important to know what type of window spacer material is being used on the insulating glass unit as it is to know what type of glass package (or glazing) is going into the window. The type of spacer material in your windows can make or break your investment! When we purchase windows from the manufacturer, we only buy windows with Super Spacer® technology (if offered by the manufacturer). Super Spacer® is the world’s only 100% polymer foam, no-metal, warm edge spacer. It contains no metal. Metal is a heat conductor and can cause condensation, The edge of the insulating glass unit is the most vulnerable to heat and cooling loss, condensation, and frosting. Super Spacer’s® No-Metal formula blocks the heat escape path and provides one of the best thermal performances in the industry.

So what makes one window better than another? Bottom line-the better the window, the more money it will save you on energy bills. There are quite a few features to compare when deciding which window is right for your home and how energy efficient it is. Here are just a few:

The way the $189 window performs:

  1. The lower the air infiltration rating, the better the window. (See our Section on Air Infiltration))
  2. The higher the Water Infiltration rating, the better the window.
  3. The higher the Design Pressure rating, the better the window.
  4. The lower the u factor rating, the better the window.
