  • Vapour barriers in basements

    One of our viewers is about to insulate his basement and he has been told that he should not run the vapour barrier all the way to the floor. Fact or fiction? You should run the vapour barrier wherever there is insulation to keep the moisture on the warm side of the wall. And in a basement insta...
  • WON'T A VENT HOLE WITH NO DAMPER COST ME A LOT IN HEATING DOLLARS?

    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...
  • ARE BROWN PAPER-BACKED FIBERGLASS BATTS GOOD VAPOUR BARRIERS?

    I went to the store and bought a box of really nifty 100 percent recycled vinyl interlocking floor tiles, the kind that stand up above a concrete floor and let the water drain through and under. I needed them to keep boxes off of a basement floor where there was occasional moisture -- and I ended...
