Condensation or fog between the window panes? Chances are the glass has broken or cracked. But the most obvious cause might be that the sealed unit has failed. This calls for a sealed unit replacement, but before that, you need to understand what a sealed unit is exactly.
What Are Sealed Window Units?
Sealed units are also known as thermal units, Thermo and insulated glazing or IG units. These are double glazing sealed units consisting of two or even more than two glass panes with adhesive spacers separating the panes. For improved insulation value and even to make sure that the unit performs well, space in-between is either vacuum or is filled with an inert gas like argon. The perimeter of the unit is duly sealed for ensuring that the gas or vacuum does not leak. The sealing is done with a kind of vulcanising compound.
It is the insulation that is of good help in keeping the house cooler during summers and warmer during winters.

Reasons behind Going for Sealed Unit Replacements
There are a good number of reasons why homeowners need to go for a sealed unit replacement. We will have a look at them below:
Window Fogging
Going for sealed unit replacement is an eco-friendly and cost-effective alternative. If you start noticing fogging between the glass panes and the windows of your home are already 15 years old without any signs of being old, it is time for you to consider a sealed unit replacement. Replacing only the sealed unit instead of the whole window will help you in saving a huge amount of money that can be used for other home improvement procedures in the future. Even condensation and misting between the glass panes call for sealed unit replacements.
Broken Windows
Another reason to go for sealed a unit replacement is when the seal or the glass breaks completely. This will not only spoil the aesthetics of your home but will also compromise the airtight sealing. This will further increase your energy bills, especially on heating the home. In this case, replacing the sealed unit will make your house more energy-efficient and safer as well.
When to Consider Complete Window Replacement?
If the windows of your home have completely worn down and simply replacing the sealed unit is not going to solve the problem, you need to go for a complete window replacement. So, when is the right time to replace the windows instead of replacing only the sealed unit? Have a look below:
- When the windows have single-pane glazing, and you are looking to upgrade to safer and more energy-efficient units.
- When the frames of the windows are completely rotten, warped or damaged.
- When cold air or drafts are noticed near the windows.
In other words, if your windows are beyond replacement or repair, it is time for you to go for new windows. Try calculating the cost of fixing a window and the cost of sealed unit replacement. If the difference is more than 50%, it is better to get new windows. But keep in mind; going for a sealed unit replacement is less expensive in comparison to replacing a full window.
Matching Existing Sealed Units with the Replaced Ones
This is important mainly when you do not want to spoil the aesthetics of your home. There might be little to no variations in colours and shades, but it is possible to find the perfect match. If at all, there are certain differences, they are so very subtle that people are hardly able to notice them.
