The only type of dehumidifier that is any good at all during the winter is a fresh air ventilation system. Mechanical and chemical dehumidifiers are not only expensive and bothersome, but they cannot generally reduce the relative humidity to less than 50 per cent -- not low enough to keep frost ...
Every paint is formulated to maximize some special characteristic, and that often means sacrificing other desirable characteristics in that particular paint. No one paint can be everything to everybody.One of the most common trade-offs in making paint is "ease of application" vs. "durability".Pl...
In Canada, other than on the lower mainland of British Columbia and on Sable Island, it is impossible to maintain a comfortable level of humidity in the house and not have frost on single-pane windows most of the winter.Using two panes of glass allows the inner pane to be warmer than the outer on...

Yes you can check if your hygrometer or humidistat is giving you the right readings. Mix into a glass, one part water to two parts salt -- like 1/4 cup water to 1/2 cup salt. Mix it thoroughly. Now put this glass and the hygrometer into a sealed plastic bag at 22 degrees C, room temperature. Wait...

Hi, I could not find this second level question on your web site. I am familiar with the humidity levels required in a home to avoid condensation on the inside on a thermal pane window- we are still getting condensation with readings in the center of the room of 20 degree C ...
Because of the seriousness of the issue, I want to take a moment to present my credentials other than that guy that has been on TV and radio for 42 years.
