Replace thermos and sealed units

Portes et Fenêtres L’Assomption can replace the thermos and sealed units in your existing installations.

Make the right choice

In some cases, thermos replacement is a wise choice to preserve a good energy efficiency on a good quality window. However, depending on the installation, replacing windows on a lower quality PVC building could be more problematic than profitable.

Experience makes the differencee

Defogging options are available on the market, however we do not recommend this approach, as we consider that the savings made by defogging a thermos do not justify its loss of thermal efficiency and the low longevity of this approach.
