If it were possible to find Energy Cube System Review and measure the length of the crack around every window, door and unnecessary opening, your total crack length could easily surpass 300 linear feet (16 linear feet per window, 20 linear feet per door and 100 linear feet to cover all remaining cracks and openings). If the average crack width is just one-eighth of an inch in size (I'm being conservative) and the length of crack is 300 linear feet (3600 inches), the actual hole size, were it to exist in just one place, would be 450 square inches or a hole that is 21.2 inches wide by 21.2 inches wide. In essence, you have a 2 ft. x 2 ft. window fully open all year long, no matter how hot or cold it is outside. Your goal is to find a way to shut that virtual window. Short of totally gutting and rebuilding the home, you will never totally eliminate all the drafts, but you can close it halfway or more and reduce the amount of air infiltration to one third or less of its current level. Insulation is gauged by an 'R-Value' which is simply a measure of 'R'esistance to hot or cold. The higher the r-value, the harder it is for heated or cooled air to pass through. The outside walls on newer homes are often insulated to a r-value of 19 or more. Their attic spaces can easily be insulated to a r-value of 30 or more. In comparison, most older homes have inadequate insulation values that struggle to reach an r-value of 2 to 3 if you give credit to the layers of wood and siding, but this is almost negligible. Even the tiniest bit of insulating can make a big difference. When performing heating load calculations, a wall with no insulation gets a heating loss multiplier of 19, compared to having a multiplier of only 6 if a 3 1/2 layer of R-11 insulation were added.
