Deciding on the Right Replacement Window

What is the best replacement window?

Choosing which options are important when buying replacement windows can be overwhelming!

Options are everywhere; some are critical for energy efficiency and durability – while others can impact the overall aesthetic of your home. We’ve heard from many homeowners like you; it’s hard to figure out which options are important.

We’ll go over what we feel is critical to your replacement windows performance and your peace of mind.

How many panes of glass do I really need?

The answer to this question depends on a few factors: what climate you live and how energy efficient you want your replacement window to be. In Wisconsin, we are in one of the coldest climates – making this a critical factor.

Triple pane replacement windows have been proven to show a significant increase in energy efficiency ratings when compared to double pane replacement windows. This can be seen by comparing the Energy Star rating of the windows. To read more about ratings, click here.

When you think about it, this makes sense. If it’s cold outside, you’ll be warmer with three layers of clothing vs. two layers.

What frame material do I really need?

You’ll need to choose a solid frame that will support the weight of the glass without warping and bending, especially important if you’ve decided to purchase more energy efficient triple pane replacement windows.

The exterior of your windows is always exposed to the elements, and you need something that will withstand not only precipitation (rain & snow) but also long periods of direct sunlight.

Do I really need gas fills between the glass?

In Wisconsin, the answer is yes! This adds to the energy efficiency of a replacement window. The gas is an insulator and works in both warm and cool months helping protect you from the temperatures outside.

What’s the best warranty for me?

Replacement Windows

You’ll hear companies offer lifetime warranties, limited lifetime warranties or they will specify a length of time, typically in years. It’s important to clearly understand exactly how long each warranty lasts, if it’s prorated based on the age of the product and if it’s transferable if you sell your home.

When you hear about a lifetime warranty, it’s always good to ask is it your lifetime or the projected lifetime of the product and find out exactly how many years that translates into.
