Today most homes have insulation within their walls ceilings and floors, however, to cut your costs, reduce energy usage, and make your home more comfortable to live in, personal improvements can be made. Unlike improvement advice you’d pick up at a Tony Robbins seminar, these ARE things money can buy, though in the long run, can more than make up for themselves in pennies spent. According to the Department Of Energy (DOE), a couple hundred dollars (20,000 pennies) can reduce cooling and heating bills by up to 30%!
Heat naturally moves from warm or hot areas to cool or cold areas. It is insulation which slows this process down. Most available insulation works by trapping tiny air pockets within material which effectively reduces the its conductivity and therefore, resistance to temperature transfers. It is this resistance which is called the “R” Value and is usually measures per the inch of material. Therefore, the more material you use, the greater the R-Value.
Insulation comes in many forms. These include blankets (rolls or batts) – (For wall studs or ceiling joists), liquid foam and loose-fill – (Anywhere they can be blown in), and rigid board – (Exterior or concrete areas). Today, newer forms called Structural Insulated Panels (SIPS) and Insulated Concrete Forms (ICFS) are actually integrating insulation material into solid building materials. This way even if you aren’t up for multi-tasking, your structure is! Some of these newer combination types may require professional installation, but some are easily installed by the common do-it-yourselfer.
As far as their make-up is concerned, insulation has a few popular classes:
FIBERGLASS - Uses molten silica sand spun into fibers. Other additives include phenol formaldehyde, acrylic binder, or boron.
CELLULOSE - Considered one of the greenest due to its reliance on a low-tech manufacturing process.
COTTON - Made primarily of blue-jean waste material and plastic, it resists pests and combustion.
Some even greener methods even use straw and clay to create new-age insulating materials!
If you are concerned on where to start, then start with your attic or ceiling. They are usually the most generous in donating your heat for the good of the neighborhood animals. Aside from having the largest surface area for temperature transfer to occur, attics also have chases, chimneys, exhaust fans, ducts and various other conduits. If you want to go further, walls and floors give off an average of 16% to 20% and floors and crawlspaces 5% – 15%.
The DOE provides Minimum R-Value Recommendations for homes in the United States based upon their heating, uninsulated space, and climate. Check out the levels in your area with the above link, however consider exceeding these levels. Exceeding the levels considered to be “code” is considered “superinsulating” your home and can be a great selling-point aside from a money and energy saver! Whether your home is old or new, it’s obvious improvements in insulation can always be made to create a never-ending benefit to both you and your ATM.
