Insulation – What a way to end the week

It is Jam Band Friday – ( http://www.youtube.com/watch?v=3JW-OU3LkM8 )

Humans burn at 98.6. If we lived in a perfectly insulated and airtight world we would have to vent our homes in the winter. Some people in colder climates have those homes, but us’ens in the uninsulated leaky drafty Midwest don’t. I tell people to put as much insulation WHEREVER they can.

What does insulation actually do for my home?

Fiber glass insulation keeps your home cool in the summer and warm in the winter, because insulation resists the flow of heat. Heat is a form of energy and always seeks a cooler area – flowing out of the home in the winter and into the home in the summer. By reducing heat flow, a properly insulated home uses less energy for heating and cooling.

In addition to being an energy saver, fiber glass insulation also acts as a sound absorber. When installed in walls and ceilings, it can reduce the transmission of sound from one room to another or from the outside. In today’s noise-laden environments, more and more homeowners are soundproofing their homes.

A well-insulated home increases the overall comfort of the home and adds to its resale value. Whether your home is new or old, it pays to insulate.

What areas of my home should be insulated?

Insulation is not just for attics and outside walls. Insulation should also be installed in other areas of your home such as ceilings with unheated spaces, basement walls, floors above vented crawl spaces, cathedral ceilings, floors over unheated garages or porches, knee walls, and in between interior walls (especially bathrooms), ceilings or floors for extra sound control.

How do I know how much insulation I need for my home?

The amount of insulation in a home varies depending upon where you live. NAIMA has developed recommended levels of insulation for various climate zones. These recommendations are based on recommendations from the U.S. Department of Energy (DOE) and the International Energy Conservation Code which is the model building code for the United States.

What is R-value?

Insulation is identified and labeled by R-value. “R” stands for resistance to heat flow. The higher the R-value, the greater the insulating power.

Where do I find R-value information when I go to buy insulation?

Insulation is identified and labeled by R-value. “R” stands for resistance to heat flow. The higher the R-value, the greater the insulating power. Manufacturers of insulation products print R-values of their products either on the bags or on the labels. In most cases, R-values are also printed on the facings of fiber glass batts and rolls.

You can use just about anything as insulation.

The Proper Choice of Insulation

The proper choice of insulation depends on its final use. In most applications, good resistance to heat flow is not the only thing you will have to consider. In specific situations, insulation may also need some of the following properties:

  • resistance to high temperatures
  • resistance to moisture flow (can it reduce the movement of water vapour?)
  • resistance to air movement (can it act as an air barrier?)
  • a fire-rated protective covering

Once you have matched the material properties with the specific application, consider the following installation factors:

  • Is it relatively easy to install?
  • Is it the best buy for the space available (either high insulating value per dollar if you have lots of open space, or high insulating value per thickness if space is restricted)?
  • Is it available locally?
  • Will it be easy to install the insulation to fill the space completely?
  • Can it conform to surface irregularities?
  • Is it rigid enough to provide support for finished materials or resist pressures against its surfaces?
  • Does one insulation require more accessory products than another (fire protection, framing, air and vapour barrier)?

In short, the choice of insulation will largely depend on how it will be used. Different types of insulation are commonly used for insulating walls, basements and attics. Fortunately, particular insulation jobs will quickly eliminate some materials, making the choice much easier.

Just copying all the types of insulation tuckered me out.
