More and more people are asking for powerful kitchen range hoods or bathroom exhaust fans. The logic appears simple, increase the power of the exhaust fan and get rid of pollutants quicker.

They are neither sealed nor insulated, and they obtain combustion air from the house through door or wall grills of the open floor joist area.

In the spring of 2004, a young and dynamic company in Quebec got a new radiant heating cable out of the laboratory and onto the market that has almost no electromagnetic radiation. "FlexTherm" from Longueuil, Quebec came out with what they call their Green Cable.

John wants to cerate a wine cellar in his basement. Here I have answered him throughly enough to perhaps help you detail your own cold room, whether it is under a concrete porch, or just built in the corner of the basement -- trying to deal with the questions of insulation, condensation, vapour ...
