Hi Their: I am front Edmonton Alberta Canada.
The problem I am having is not with a house but a buisness that repairs car stereo's. We must keep the room at no lower than 30% humiduty and in the winter when the temp goes below 15 degrees below zero (celsius) the windows sweat.
So much so that the water runs on the floor, I might mention that the windows are 8' high and about 16' long. The windows are double casement windows in a metal frame
Any ideas that you folks would be greatly appreciated.
