How to Stop Water Condensation

If you’ve been following my blogs, chances are you’re curious as to how to do this.

New technology has improved window performance, but glass is still (usually) the coldest surface in a home. When that’s the case, water droplets of dew will form there first. Simply put, water just returns to its liquid state.

The bad news is, condensation can cause serious problems to a home and its occupants. It can damage paint, wood and drywall and cause mold and mildew that can ultimately make an environment so unhealthy a home can be uninhabitable.

The good news is the homeowner can change the conditions in the home and eliminate condensation forming on glass doors and windows.

What can they do to stop this?

They must either lower the humidity or increase the glass temperature.

Homeowners can do this three ways.

  1. Get windows with a high CRF (Condensation Resistance Factor) properly installed in their home.
  2. Reduce the humidity of each room to a comfortable level. This can be achieved by something as simple as opening a window.
  3. Make sure heated air in the room makes contact with the interior glass surface.

When interior air becomes drier or the glass surface becomes warmer, the dew point changes and condensation will not occur.
