Here are some common vapor barrier materials: Polyethylene film. aluminum foil, aluminum, paint, varnish and rubber base paints, and urethanes. The recommended in- sulation levels for Canadian homes have been rising through the years, reflecting increased heating costs and concern for energy con- servation. The precise level of insulation which can be justified on economic grounds (cost of insulation vs. fuel saving) varies with climate, fuel costs, insulation prices and other factors. It is possible, however, to recommend one set of minimum insulation levels which are generally ap- plicable across the country. The recommended levels for existing and new housing will differ because current construction practices often limit the amount of insulation that can be added. However. innovative construction techniques will allow higher levels for new housing in the future. The building codes for new homes are presently being re- evaluated and updated to meet today's energy cir- cumstances. New con- struction techniques, such as 6 -inch wall studs and exterior insulation, are being con- sidered to make new houses suitable for the energy pinch ahead. Even solar heating systems are being developed and tested.

They should not be used in applications which might expose them to open flame inside a building.
