Aside from the controversy about health problems, this was a poor insulating material in the first place. It was initially given a high R rating, but was subsequently down graded sixty percent by the Canada Mortgage and Housing Corporation, because it tended to shrink and leave gaps in the i...
For detailed R value recommendations, search keyword "R-Value" for the title "WHAT ARE THE RECOMMENDED INSULATION LEVELS?".Note that in the previous answer, some of the common options for basement insulation does not even meet the minimum recommendation of RSI - 2.1 (R-12). Manufactures of all...
No matter how you cut it -- a good window is still a lousy wall. Glass has almost no thermal resistance (RSI - 0.16; R - 0.88), and a single-pane window in Canada not only makes a lousy wall in winter, but it makes a lousy window too -- you can't see through the thick layer of ice! But a ho...
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....
Back in the early 1980's there existed some fairly simple tables to guide homeowners in determining the insulation levels that they might want to put into the various parts of their houses. We had tables for standard houses, for energy efficient houses, super insulated houses and even for trying ...
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...
