Ahhhhh… Spring has FINALLY arrived.

The days are getting longer, the sun is getting warmer, and the snow is starting to melt. But between us, time seems to be moving slowly. We will have to wait a few more weeks to see nature wake up. In the meantime, let’s endure the unstable temperatures from Mother Nature that might cause exterior condensation on your windows. Not familiar with the situation? Great, we’ll explain what you need to know about this phenomenon in our article of the month.

First, it’s important not to confuse exterior condensation with interior condensation.

Remember, interior condensation occurs when the surface of your window is cold, and the moisture in the ambient air (inside your home) cools upon contact and condenses. If you haven’t had the chance to read our article on the subject, click ici.

Now, let’s talk about what interests us, exterior condensation.

In the fall or spring, condensation may form on the exterior surface of your windows. Why? This phenomenon occurs when humid air comes into contact with a cold, smooth surface, like a mirror in a bathroom.

Don’t panic. This phenomenon, linked to particular climatic conditions, is completely normal. Rest assured, it’s even a good sign! Why?

Because it’s not a manufacturing or installation defect. On the contrary, it means your windows are well insulated. Highly efficient energy glazing reduces the amount of heat escaping to the exterior surface. (The glazing is cold outside and warm inside).

From now on, when you see exterior condensation on your windows, remember and be reassured that you have energy-efficient and high-performance windows.

We cannot change the situation, so you’ll just have to wait for the wind to pick up or for the sun to warm up the exterior surfaces of the house for the condensation to dissipate.
