If a home lacks good attic insulation, then the family living in that poorly insulated structure must rely on air conditioning, in order to stay cool in the summer. That means spending lots of money on energy, so that the air conditioner keeps working. Energy costs can be reduced through utilization of an item that functions as protection from the heat.

Features of materials used in making insulation

The sort of material that typically gets used during the construction of a family’s house does a poor job of keeping heat out of that same residence. In contrast to such material, the substances used in insulation tend to repel heat. Roofing Contractor in San Mateo knows that present day homeowners can choose from a variety of insulation types. Each type was fashioned from a different substance. Some were made from mineral wool; a manufacturer used either fiberglass or cellulose, when making others.

The attic’s function

In the absence of any insulating material, an attic serves as nothing more than empty space, one that is located under the rooftop. The air in the attic can transfer heat from the roof to the home’s ceiling. In attics that contain insulation the process for the transfer of the warmth in that hot air proceeds more slowly.

When heat travels more slowly, it fails to warm up the heated area to a great extent. Imagine how hard it would be to warm-up by standing 20 feet from a small fire in a fireplace. If you had some form of protection, you would find it even harder to get warm. Insulation functions like a form of protection. Heat travels through some substances better than others. It does not travel very rapidly through substances such as mineral wool or fiberglass. Those belong on a list of insulating substances.

What homeowners ought to know about installing insulating materials?

Fiberglass is the substance that gets used in most insulation. Fiberglass is light and easy to place in a roll. Once it has been unrolled, then professional workers can place a long section between the beams in the attic.

Unfortunately, there are some spots in every attic that are hard-to-reach. Homeowners might find it easier to deal with such spots by using a different type of insulation. There are 2 useful alternatives to fiberglass on the market.

One of those is cellulose. It has been made from recycled paper and cardboard. Homeowners that care deeply about issues like sustainability might prefer to order the installation of cellulose insulation.

The other type is foam. It can be sprayed on the walls in those hard-to-reach areas. Like the other insulating substances, it slows the process by which warm air carries heat from the rooftop to the home’s ceiling.
