Buy a house insulation guide


Are you spending too much on your energy bills? If you isolate your home is not until he died, it may be good. According to the U.S. Department of Energy, and 44% of the energy used in the average American home goes toward heating and cooling. If you have an attic, walls, or are underinsulated floors, and a large part of air-conditioned expensive and can make a beeline for the great outdoors.

Insulation saves you money by reducing heat loss and the reduction of projects, which makes the house more comfortable. Some kinds of sealing air to penetrate, and a major contributor to heat loss. To what extent thermal insulation resists the flow is measured and appreciated by R value. Insulation materials vary in their values R one inch of fish.

How much insulation is enough?
Have built homes in the past few years, or may not be optimal levels of insulation, depending on how and made a lot of attention to energy conservation when it was built. But nearly all the old houses are likely to be non-existent. The best way to find out if your home has enough is to call your local utility company about obtaining a review of energy "."

The recommended minimum R-values of the homes vary according to climate and can be affected by how to build a house and the type of heating used. Here are some simple rules:

DiagramFor home insulation moderate climates, Loire 11 in the walls and floors War 19 in ceilings below attics ventilation. To a temperate climate, Loire 19 in the walls and floors and R 30 in ceilings below attics ventilation. For cold climates, Loire 19 in the walls and under floors and R 38 R 49 in ceilings below attics ventilation. (Visit the Web site of the Department of Energy www.energy. Governorate of more specific recommendations from the region.)

Insulation where it belongs
Insulation must be installed inside any barrier that exists between the blanks and non-hot hot. In essence, should form an envelope around the house.

Attic is the place to isolate the most important. Buttoning up to the non-insulated attic can reduce the value of the fuel increased by 30%. Achieve a minimum of attic insulated to the optimum levels of insulation can yield similar results for the amount of additives. If the attic is not finished but is to isolate a relatively easy task.

If the finished attic with walls and ceilings should be installed insulation at the end of the day in knee walls and roof beams outside the Old City in the knee and, if possible, between the rafters of the ceiling attic (However, ventilation between the rafters of the eaves for should not be be blocked Ridge).

It is also important to be isolated from the walls of the house, but at the home of the elderly, and this is not always isolated from the pencil. Walls in the construction before wall coverings applied is a breeze, but then immunized the truth is expensive and complicated (unless you're remodeling or re-siding the house). If your home is uninsulated walls and is located in a cold climate, ask the contractors to isolate two or three bids, and then see how much time will it take to pay the cost savings of 16% -20% annually on your energy bill.

Insulating crawlspaces is also useful; this can be reduced 5% -15% of the cost of heating. If crawlspaces are reasonably accessible, isolation generally very easy. The end of the outer walls and institutions in the basements should also be isolated.

Types of insulation
It's easier to consider the various insulation materials by major categories (although there is some overlap): batts, blankets, loose fill, blown away, plastic foam, rigid boards, and expressive. These categories are based primarily on the form of articles, and method of installation.

The Batts, diverse, blankets and more familiar to owners of homes and the most common type installed by the do-it, intentionally. Main material is mineral fiber insulation, either fiberglass or rock wool fibers. Batts are sold before cutting ribbons, blankets, and lists continued. And sold in each of these match the traditional view wall and roof nail - Rafter spacing so that it may be just the pressure or stapled in place. And sold both with and without the Kraft covers or reflect foil/vapor- the mentally retarded. (Vapor barrier faces towards the warm side in winter, and are used without the types of barrier when you add to the existing insulation.)

Advantages of batts and blankets and they are available and easy to do it yourselfers to install, and relatively affordable. Installed in the breeding of non-standard joist spacing, or take a little extra time since the material must first be cut with a knife utility.

Loose fill insulation, is supposed to be poured, stuffed, or blow up in a place made of fiber glass, rock wool and cellulosic fibers, or expand the vermiculite and perlite. You are made of metal the same as woven batts and blankets, but leave loose or made into pellets. They are used in attics and walls.

Provision cellulosic isolation from recycled paper (mostly newspaper) and wood fiber which has been dealing with fires. It is used in both attics and walls.

Vermiculite provision of raw mica, perlite comes from volcanic rocks, both hot and expanded in the article, a thin non-combustible material that is used to isolate some of the ceilings and walls (concrete block the most part).

Loose fill materials that are sold in bags or bales, and works well for insulation between the ceiling joists in the attic is accessible. To fill the cavities of the wall, and pneumatic equipment is often necessary. When you use a loose fill insulation in the attic, it's usually necessary to install vapor barrier (plastic sheeting) first.
R-values in apprx. 1 "thickness

  • Fiberglass blanket is 3.27
  • Rock wool blanket and is 3.2 to 3.7
  • Fiberglass loose fill (blown) from 2.2 to 4.0
  • Rock wool loose fill (blown) 2.9 to 3.6
  • Cellulose loose fill (blown) from 3.2 to 3.8
  • Vermiculite loose fill (poured) 2.27
  • Perlite loose fill (poured) 2.7
  • Spraying polyurethane foam from 6.0 to 7.3
  • Fiberboard Packaging 1.32
  • Expanded polystyrene (extruded) 5.0
  • Molded expanded polystyrene ()
  • 3.85 to 4.35

Polyisocyanurate Board (unfaced) 5,8-6,2
Polyisocyanurate Board (experience) from 7.1 to 8.7
Homeowners who need rental equipment Pneumatic blown loose fill insulation is installed by professional installation, or in some cases. Effectiveness is a direct result of the application of this technology, so it is usually best to have this done by a pro.

Materials can be unloaded to the device, and that fluffs and beaten during the hose in the areas between the ceiling joists or wall cavities between studs. Isolate itself could be composed of cellulose and mineral fiber loose, fibers, pellets, or fibers coated with an adhesive (the latter is the most effective in the sealing cavity and the least likely to settle once inside the wall).

Foam or spray in place insulation (typically polyurethane) is installed by professionals who have special equipment to monitor and enforce the mix. It provides very high R-values, does not shrink or settle once in place, and projects that caused the infiltration of air masses that it is compatible with every nook and cranny, and provides a barrier to moisture.

Sprinkle in a place designed for types of new construction, and can be used in walls and ceilings wirelessly, and around the perimeter of the institution. They are relatively expensive. Takes note of because of emissions of steam are likely to be hazardous to avoid urea formaldehyde foam insulation in place:.

Solid foam insulation board is made of a number of different materials: asphalt trans Council fiber, polystyrene, polyurethane and polyisocyanurate. And use these panels are generally rigid in the new building (or re-siding or reroofing), which can be installed on the wall or ceiling packaging, or insulation under the interior walls or around foundations. To be classified as flammable, it can not be left vulnerable. It is permissible for plates and foil facings on one or both sides to reflect heat.

Reflective insulation, made of aluminum foil, are most effective in hot climates to prevent heat radiation. Effectiveness depends on whether the foil is a piece of paper flat, and is used to prevent the transmission of heat through the roofs, or a hindrance to have multiple layers separated by spaces, air, and appropriate to reduce heat gain through roofs, ceilings, walls and floors.

Get the job done
Before contracting with loyalists to isolate your home, and get two or three bids. Compared with apples and apples, and be sure every attempt to clearly describes the article is used, and set of values research that will be installed in each area of the house. When the material arrives, it must be labeled bags with valuable information R; with loose fill insulation, check to make sure you install an appropriate number of bags.

Also talk with the private contractor for each of the ventilation and control moisture. Ventilation is important to ensure the quality of air your home is energy conservation without losing unnecessary. And must in most climates, vapor barriers are installed at the insulation to prevent vapor, naturally present in the air, and the collection from within the walls of the insulation, ceilings and floors, and ceilings. In most climates, and steam the mentally retarded, such as foil facing on batts and blankets, or filled with loose, 6 ml plastic sheeting, polyethylene, must be installed in the side of warm in the winter of isolation. Existing walls that are filled with blown - in to repel the insulation coating can be coated with low vapor permeability.

Last but not least, be sure to seal all cracks and crevices that allow air infiltration, using the complex dam and Weatherstripping. To do so is the key to take advantage of energy savings and comfort of the insulation your new.
