Another sign that your window seal is worn down is when you notice the formation of condensate between the glass panes. This signifies that the gas between the glass panes has been depressurized and is now comprised of air and water vapour instead of argon and krypton which are more dense than air and have better insulation properties.

Sealant

Modern triple-pane or double-pane windows have an inner seal (or seals) between their panes. These seals aid in keeping argon or krypton gas in the window to improve its insulation properties. The seal inside is susceptible to breaking, and could lead to a variety of problems including condensation between the panes and drafts. A broken seal can also result in an improvement in the efficiency of your home and higher energy bills.

Wood frames are very popular and provide the benefit of being durable and efficient. To prevent rot or insect infestation, they must be regularly stained and painted.

A broken window seal can cause condensation and fogging. This can happen due to depressurization or the loss of inert gas used to fill the space between glass layers at the factory. A professional defogging solution can be employed to solve the problem, but it is not the best solution. The process of defogging will only remove the moisture causing fog, but it won't replace the argon gas originally used to increase the insulating value of the window.

In some cases the issue is caused by extreme temperature changes. This can cause the glass to expand and contract, which may cause pressure on the window seal. In addition, harsh weather conditions like high humidity can cause a leaky window seal.

If the window is still covered by warranty, you should consult the manufacturer to determine what alternatives are available for replacing the seal. This is a far better option than repairing or replacing the IGU on your own. It could be expensive and difficult.
