Can vacuum-insulated glass stop condensation and mould on your windows?

Vacuum insulated double glazing can stop condensation on the inside of your windows because the vacuum layer is so well insulated it actually stays warm.

Condensation is common on the inside of windows 

Apart from visible moisture accumulating on the inside of glass, it can lead to the growth of black mould, poor indoor air quality, and corrosion of fittings as the moisture pools at the base of your window frames.

It often causes damage to woodwork and the paint finish on a window, because the internal surfaces of a window are not built to shed water like the outside is. And there is less fresh air circulating indoors to evaporate the water, so it sits around for longer.

The longer a condensation problem is left unattended the more money will need to be spent to repair damage. In extreme cases it can require complete window replacement.

What causes condensation on your windows

Condensation on windows will always occur when warm, moist air contacts a sufficiently cold surface, so solutions fall into two categories:

1. reduce moisture in the air

2. increase the glass surface temperature

Reducing moisture in the air is a good idea, but isn’t always practical 

We breathe out water vapour all the time, and you can’t hold your breath for ever! It’s also commonly caused by moisture from your daily shower, boiling a pot of pasta on the stove and from the moist in our indoor house plants.

And whilst you can open a window to let the moist air out, you’re unlikely to want to in the coldest weather, when condensation is at its worst.

You could run your heating hard all through the night to keep the glass warm. But who wants that massive energy bill? Not to mention the greenhouse emissions.

Vacuum insulated double glazing can stop condensation on the inside of your windows

Enter Glavenir vacuum-insulated glass.

Glavenir double glazing by Panasonic is a vacuum-insulated glass that perform better that triple glazing…! The space (or vacuum) in between the double glazing of Glavenir is so well-insulated from the cold night air, that it can easily stay warm and dry inside. 

The cover photo shows condensation on a pane of Glavenir after a cold night in Tasmania. The condensation was on the OUTSIDE of the glass, where the glass was cold, while the inside pane remained warm and perfectly dry. 

Visible proof of the outstanding thermal performance of vacuum-insulated glass!
