When you’re in the market for replacement windows, you’ll probably hear a lot about the NRFC ratings, the glass and the installation itself, but another important factor is the replacement window spacer.
What is a Replacement Window Spacer?
Any replacement window that has more than one pane of glass will have some type of spacer system.
The spacer is not simply the space between the panes of glass but it is the material that is used to hold the glass in place from between the panes. It also keeps the seal of glass air tight to keep in inert gas like argon or krypton gas.
Why is the Type of Spacer Important?
The spacer is one of the factors that affects the overall efficiency of the windows.
If the spacer is aluminum, the efficiency of the window will not be as effective as a spacer made of stainless steel (which is less conductive).
Many window manufacturers are now offering ‘warm-edge’ spacers that are generally made of a composite material. This type of spacer can help to improve the condensation rating (and by improve, we mean lower the likelihood of condensation, but you can read more about that here).
What Type of Window Spacer Should I Get?
My two cents worth is that you can ask the company you’re considering hiring if they have a some type of ‘warm-edge’ replacement window spacer. Generally the cost to upgrade should be quite nominal.
It’s included in our triple pane windows at my company, but nearly any replacement window company worth it’s salt should be able to upgrade double pane windows with a high performance spacer as well.

I didn’t know that they sold replacement window spacers out there. It might be nice to have if you have a faulty one or have something damage the one that you got. I think it would help to also look into seeing if it would help to have the window completely replaced.
I had my son just break one of my windows. It was an accident. Kids will be kids. I need to get it changed out, though. I had no idea there was a special material used for spacers in between the panes of glass. I will have to make some calls and see if I can find a good company to replace my windows.
I’m glad you explained the significance of a window spacer. It’s understandable that many are unaware of its purpose or even that it exists for that matter. Like you said the right spacer can contribute to an increase in efficiency to the windows which can make them last longer and serve their purpose.
