  • CAULKING & SEALING

    Caulking is actually a common name for what is properly called "sealants".Contrary to the recommendations of almost every handyman book from the US, do not caulk on the outside of the house except where necessary to keep rain, driving rain and blowing snow from penetrating into the wall. Any ...
  • HEAT LOSS TESTING

    There are really only two practical methods to scientifically test for heat losses in a residential house:Infra-red thermography: using infrared sensitive film you can take a "heat picture" of the house. Hot and cold areas show up on the infra-red film to give an image of your house -- it's more...
  • What does R-factor mean in thermal insulation?

    When scientists measure the movement of heat (thermal transfer) through a material, they calculate it in something called the U-factor, a measure of thermal conductivity. A small number indicates a material that conducts heat poorly and a high one indicates a material that conducts heat well....
  • Is aluminum foil an insulation?

    Steve writes: Could you tell me if tinfoil vapour barrier is " legally" considered insulation? I bought a house two years ago and just discovered that there wasn?t any insulation in the walls, only this tinfoil stuff. The sellers lawyer claims this is classified as insulation so the se...
  • Blocking drafts through existing electrical outlets

    You have all seen, maybe even used the little foam gaskets that are supposed to block the cold air from coming in through the electrical outlets, as you can see my smoke pencil flowing through the outlet in the first photo. The air sealing experts at CanAm Air Sealing showed me how to make t...
  • WHY IS THERE FROST ON THE RUG?

    On windy days, houses in the Prairies often develop a small frost line on the rug about an inch away from the wall on the north or west side of the house. Here the wind is succeeding in lowering the temperature of the most poorly insulated part of the house -- the floor boards. In most construct...
  • Where to find WEATHER-STRIPPING that will fit your window/door?

    Weather-stripping is used to seal air leaks at any opening in the house that moves -- doors, windows, and traps. If you need to be convinced of the necessity of doing a good job of weather-stripping, check out Air Barriers in the search tab above -- or look at your last heating bill.   Much of ...
  • Infra-Red Thermography -- heat X-Rays of your home

    There are several non-destructive ways that we can see what is going on inside the walls, ceilings and roofs of our homes. Simply watching the melting patterns of a light snow on the roof will tell you where you have insulation and where you have heat losses. In the first photo this was an unheat...
  • WILL REFLECTIVE FOILS HELP TO INSULATE MY WALLS?

    Yes but no. (I thought you'd like that one.) Aluminum reflectors will turn back RADIATION heat losses into the house, and in fact help to limit heat losses. However, they will only work if there is at least a half-inch air space in front of the reflective surface and the surface remains clean an...
  • Tankless water heaters

      More and more we are seeing tankless water heaters, both for replacing our regular hot water tank and for hot water radiant heating. Do they work? Where did they come from? Are they proven technology or new gadgets? MOST OF THE WORLD IS TANKLESS Actually, we may want to ask: "Where have we b...
