Insulating Your House

It may seem an interesting selection of products, but isolation is an essential material in determining the energy efficiency of your home and the amount of money going to end up spending for cooling and heating. When properly installed and properly on your floors, walls and ceilings, this product is relatively inexpensive, maintenance-free and quietly did his job for the life of your home.

The right insulation for your home depends on where it is used for building and energy codes for a particular city. Your contractor can help you choose the best options to suit your needs.

Here are some useful information that will help you determine what insulation is right for your new home:

Insulation Working:

Insulation works by slowing the flow of heat trying to leave your house by blowing up millions of tiny air holes. The air space smaller and more numerous, the better the insulation. Your home is easy to lose heat to the ambient air by radiation and heat conduction, the heat moves from hot zone to a cooler area - some from your heated house outside. Heat is also lost through leakage - the hidden holes and cracks in your home.

Types of Insulation:

Manufacturers have many options for the type of insulation used. All the insulation can be effective if properly installed and, together with a continuous air barrier. The insulating materials are classified according to their ability to resist heat flow. 

ENERGY STAR ® qualified homes can include one or more of the following types of insulation:

* Batt Insulation: Batt insulation is typically mineral fibers (glass or rock wool) and manufactured in blankets of various sizes and thicknesses. Batt insulation is usually set between the posts, beams and girders and must comply with the wall, floor, ceiling, or in the cavity, without gaps, voids, or compression.

* Blown-in Insulation: This insulation is usually fiberglass or cellulose and is literally blowing the walls and floor through a large pipe. Blown insulation should be covered with wall cavities, and even thickness throughout the attic.

* Products sprayed or injected foam: These types of products are usually made of polyurethane or the like, and it is injected or sprayed into the cavity, where they expand to the desired thickness.

* Rigid insulation: This insulation is usually synthetic polystyrene and polyurethane foam that expands or are formed in large sheets. Rigid insulation can be used to provide a continuous thermal barrier in basements, crawl spaces and outside walls. This product is also available from some manufacturers as a spray expanding foam, which when applied expands to twice its size, making it ideal for filling the nooks and crannies.
