Homes that were built 60 years Electricity Freedom System Review ago or more generally allow much of their heated or cooled air to escape with no effort at all. Since most older homes weren’t built with any form of energy efficiency in mind, it’s likely that your energy costs would be three to five times greater than that of a newer home built during the past 10 years. Why is this. Why is your home missing many of the basic things that are standard on new homes. There are a few possibilities…
Air infiltration is the process by which air enters through cracks and crevices in the siding, through roof overhangs, and around door and window frames. Infiltration, more commonly referred to as ‘drafts’ is simply the direct result of ‘loose construction’ where there are little to no seals around the edges of what helps define the outside of the home and the inside of the home.
If it were possible to find 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.
