If caulking effectively blocks air leaks and water infiltration through your windows, there is no input when a thermos window has degraded to the point of being fogged and dirty between the two windows.
Whether you notice it with your eye or through a thermographic inspection,a degraded thermos glass window is the opposite of what it was designed to do.
When, after a few years, the sealing seal has lost its seal, we see:
- the mist formation between the two windows,
- the stains between the two windows,
- take-off of the joints cracked by drying out.
These works are those of the Elite caulking glazier. It works on your double-glazed windows when the problem goes beyond the caulking itself.
With 15 years of experience in the Montreal area, our artisan-glazier is a real expert in replacing thermos windows and guaranteeing a careful, professional work that will give a youthful boost to your windows with degraded insulation.

What is Thermos?
The “thermos” is simply the other name of the glass, tile, glass or glazing.
It is because this element of two or three sealed windows is placed in the frame of the window that its name is identified as: Thermos – double or triple glazing, thermal or phonic insulating glass, glass reinforced with break or not …
Compared to a single tile, the thermos improves the energy performance of the window. How?
Between the two or three layers of glass, a low-emissivity membrane and a filling gas are added.
A thermos window will remain efficient for 15 to 20 years depending on whether:
- It is never broken,
- The thermal bridge does not deteriorate,
- The sealant remains effective,
- Seals age well,
- And that no mist forms between the two or three windows.
It is the mist that forms between the windows that testifies to the degradation of your window with thermos glass. This often corresponds to a unsealing of the unit or one of the reasons mentioned above.
We can unpack the thermos.
The condensation accumulated between the windows of the thermos can be treated by debugging.
If condensation is inconvenient, (the transparency of the glass is diminished), the solidity of the window frame is not reached. Also remember that removing the mist does not change the energy efficiency of Thermos.
To de-sleep a window, we practice two small holes drilled in the thermos: 1 outside and 1 inside. A special stripper is inserted to restore the glass to its original shine and then the two holes are closed.
This solution is only temporary…
A few months? A few years? And if it seems economical, it is recommended to consider replacing the thermos… Not necessarily overpriced…
Replacing thermos
If the window frame is in good condition and does not need to be changed, replacing thermos is an effective, sustainable and economical solution.
Cheaper than replacing the window, installing a new thermos has a real impact on the quality of your insulation, thus heating costs in the winter and air conditioning in the summer.
The work consists of disposing of the tired thermos (the double or triple defective old glazing) and installing a new thermos custom made in the workshop.
The window itself is not touched. The operation is fast and makes no dirt in the house.
Some handymen try to replace and install the new thermos themselves.
Think twice, air or water infiltrations are waiting for the slightest fault. The feature of the thermos presents a risk of breakage of the parclose or other element of the frame.
Professional guarantees
The guarantees usually offered on the work of replacing thermos windows
- Five years against the mist on regular thermoses,
- Ten years against the mist on the real energy thermoss LOW-E Argon,
- Fifteen to twenty-five years on Thermos Caloriverre according to their quality,
- Five years on aluminum in aluminum overlay.
Time degrades Thermos windows
The mist between two windows and the tasks that accompany it are caused by the drying and cracking of the sealing joint. The seal is no longer airtight, Argon gas (or other) escapes, moisture enters, dust attaches to the inside of the windows.
The uniqueness of the thermos double-glazed glass, permanently damaged, needs to be restored, renovated in order to regain its thermal resistance coefficient (usually R-2) and a new radiance of its aesthetic.
The degradation of a thermos window is often an alarm that requires an inspection of the other windows of the house. If the north windows are most exposed to premature degradation, the alert will be used to check all the opening joints.
Replacing the glass rather than the window!
Replacing a window is a specialist carpenter’s work! Features window, opening clearance, cost of a new model, installation, finish, caulking, paint.
Is it necessary to dispose of everything when only the change of the defective double glazing would be enough to restore
- Aesthetics at the window
- And efficiency to the insulation coefficient
