Condensation is a natural reaction to contrasting temperatures, and if you can easily wipe it off your windows or doors, then you're well on your way to dealing with the problem. But if excessive moisture creeps its way in between the glass panes of your windows, then you may have a real problem on your hands. In this post, we're answering the question is condensation between window panes a problem.

Condensation is a result of high levels of humidity reacting to colder temperatures on a surface. You will notice excessive condensation after a hot shower, doing laundry, or cooking food. The warm moisture in the air condenses in water droplets on colder surfaces, usually windows or outside walls. Also known as window sweating, any excess in moisture in the home can cause problems.
Now, think back on that steamy shower; the steam escapes the shower area and excess moisture merges with dry air causing condensation on mirrors, walls, and windows. Eventually the condensation will dissipate just like it will on windows. If you want to use that mirror immediately you can usually wipe off some of that condensation, unfortunately that's not the case when condensation occurs between window panes because it's enclosed in an area that we can't reach.
Condensation occurs when warm, moist indoor air collides with a cool surface. In cold seasons, glass can be one of the coldest materials in your home and it attracts the warm air around it. When that warm, moist air hits the surface of the glass the air becomes a moisture droplet. If the seal around the perimeter of the glass has deteriorated moisture can work its way between your glass panes. Eventually when the desiccant becomes saturated with moisture you'll see condensation and fog on the glass surface that can't be wiped away because it's between the glass panes.
If your home is not adequately ventilated, high moisture levels will create condensation. There are things you can do to reduce this, which we will discuss later.
Yes. Condensation between window panes is a problem that reduces the efficiency and performance of your windows. Excess moisture in and around your windows can cause the mold and rot in your window. Mold and rot are bad for the structural integrity of the window, the surrounding building materials, and for your health. Some homeowners ignore the problem but there are ways to prevent condensation and those tactics are helpful whether you are experiencing condensation between the glass panes or not.

A window that is regularly covered in condensation is a problem.
Your windows aren't that only structures and surfaces that can suffer damage due to moisture. Walls, doors, and ceilings can also bear the brunt of the damp. Curtains, artworks, and anything close to the developing mold will also be affected. For general moisture management, try the following things:
Condensation between window panes is a defect that warrants calling an experienced window technician. Explain what you're seeing to the technician so they can provide the proper recommendations.
Foggy windows are a common problem for residential & commercial windows alike yet there seems to be a lot of misinformation out there in regards to what causes it. Windows whose glass appears to be foggy can be broken down into two categories: condensation on the exterior surfaces of the glass and condensation on the interior surfaces of the glass. The former is a common occurrence and there isn't a whole lot that can be done to remedy it; the latter is a more serious problem and indicative of the need for replacement.
Insulated glass windows combine many panes of glass into one window. Double and Triple-pane systems are becoming the industry standard for windows. Get the facts about how they can help reduce your home’s energy consumption.
