Less expensive and more environmentally friendly

You must act quickly when fog first appears on your windows!

The moisture can cause stains that, when dried out, leave a limestone film between the windows.

An over-stained or damaged thermal window cannot be defogged.

Defogging: an effective and environmentally-friendly procedure!

Step 1 – Visual Inspection


Our technician will first visually inspect your thermal windows, offer all possible solutions and then provide a detailed quote.

Step 2 – Drilling and Injection


Following the approval of the quote, our technician will drill two very small holes on the exterior window. A cleaning solution will then be injected to remove all dirt.

Once the window is thoroughly cleaned, our technician will then inject a drying product to remove all accumulated water and moisture.

Step 3 – Drying


Finally, once the window has dried out, our technician will install transparent and weatherproof plugs to seal up the two small holes pierced earlier in the process.

Replacement of thermal glass

More economical than replacing entire windows and frames

Replacing the thermal glass is recommended when defogging is no longer possible as a result of excessive staining or deterioration of the thermal glass.

However, window frames must still be in good condition in order to replace the thermal glass. If that’s the case, it will be possible to only replace the thermal glass and greatly reduce your cost.
