What is a thermos change and why do it before winter in Quebec?
Quebec winters are known for their icy temperatures, and Laval and Greater Montreal are no exception. To get through the cold season in comfort, it's essential that your windows are in good condition. But did you know that it's not always necessary to replace the entire window when the problem is just the "thermos"?
What is a window thermos?
A thermal insulation (also called sealed glazing) is a double, or sometimes triple, pane of glass designed to provide better insulation. Between the panes, there is air or an insulating gas that keeps the heat inside in winter and the coolness in summer.
Over time, the sealant can wear away, causing:
- Condensation between the windows
- A loss of energy efficiency
- A feeling of draft near the window
In this case, it is not necessary to replace the entire window: a change of thermos is sufficient.
The benefits of changing your thermos before winter
- Energy savings: better insulation reduces your heating costs.
- Increased comfort: no more cold windows and unpleasant drafts.
- Durability: you extend the life of your windows without having to replace everything.
- Aesthetics: your windows regain their clarity, without fog or stains.
- Home Value: A well-maintained property retains its value on the market.
Why act now?
In Laval and throughout Greater Montreal, winter sets in quickly. Waiting can mean spending several months with:
- A heating bill that is too high
- Steamy windows blocking the view
- A loss of comfort in the home
Changing your thermos before winter is therefore a smart and economical investment.
