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 ...
When you're thinking about changing the windows in a house, you need to make one fundamental choice: whether to slide the new window into the old window frame (the first photo), or whether to remove the old window right down to the structure of the house (the second photo) and replace the whole t...
Yes, a vent hole without a damper will cost you heating dollars. Generally they should be closed with dampers. However, if the vent hole is not an uncontrolled leak but a planned part of the system necessary to create a high neutral plane, then a damper should not be used. It will cost you muc...
There is a lot of debate about whether to put a vapour retarder (vapour barrier) on an insulated wall behind shower tiles. The code has not historically been specifically clear on this so we get lots of different interpretations. What the code does say clearly is that we should not have two vap...
To my mind old fashioned hardwood floors are far more trouble than they are worth, especially now that we have better and better Engineered Floors available. An engineered floor is not a cheap plastic laminate on masonite floating floor. It is a very stable, usually pre-finished, real massive h...

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...
Ventilation in a Canadian attic does very little to remove moisture when the temperature in the attic is below freezing. During that time, the moisture is in the form of Ice and the passing air simply won't remove it -- whether you have passive vents or power vents. When things warm up, if the ...
Answer One "Planned-holes-high-in-the-house" are part of buiilding science considerations as to how air moves in buildings creating pressure differences that can help to keep houses dry and mold free or can help to trap pollutants in the house or even in the walls.A planned-hole-high-in-the-house...
