If you spot a developing condensation or fogginess inside the window, there might be a problem with your window seal.
The cause of this problem is primarily a failed edge seal that secures the window panes of the glass.
Getting annoyed and frustrated with this problem, you might wonder if you could do something about it.
Of course, the answer is yes.
Fortunately, you can fix a window thermal seal for good.
Thus, we will discuss all you need to know about window thermal seal repair.
Anatomy of a Window Thermal Seal
Typical thermal windows have two or three panes of glass with open space in between.
This assembly is usually called an IGU, which stands for Insulated Glass Unit.
Sometimes, they are called insulated windows or thermopanes.
The space between the window panes of an Insulated Glass Unit has an air suctioned containing inert gas such as krypton or argon.
This inert gas slows the passage of heat through the windows.
Moreover, it is less heat-conductive than a vacuum space and air.
You can watch this video to have a more in-depth knowledge of IGU.
However, if the seals protecting the IGU break, the inert gases escape.
As a result, moisture and air enter between the spaces of the panes.
This could lead to the IGU losing its insulating capabilities.
This failure in the IGU means a potential build-up of fogginess and condensation inside the window glass.
With this kind of problem, you do not only lose the aesthetics of a window.
You also lose the energy-saving features of the window.
Understanding IGU Seals
Moreover, the edges of IGU windows are inserted in a window seal.
If you look at your double-pane window, you might think it only has one seal.
In reality, two seals are working together.
One seal is in the inner portion of the window made of polyisobutylene (PIB).
The outer sealant, on the other hand, is made from a rubber-like material.
It functions as an adhesive that holds the glass unit together to keep it from falling apart.
These window seals are meant to last long for up to decades.
However, they eventually fail.
Seals can be damaged depending on how you use your windows.
In addition, an improper installation can cause an IGU window to eventually fail.
Besides this, a seal can also fail due to old age and the quality of the window.
Hence, before you buy a thermal window, make sure it is high-quality.
How to Know if the Window Thermal Seal is Damaged?
You can easily spot a broken window seal if there is moisture between the glass layers.
You might have wiped the fogginess through a cloth, but it won’t go away.
Another indicator that a window seal is broken is when you see beads of water in the corner part of the window.
Even worse, you can see haze across the glass, which interferes with your view from the outside.
