Insulation For The Attic

Many people neglect to properly insulate their attics, simply because they don’t understand how important it can be. Having the right type of insulation in your attic can result in significant savings on your power bill, and can make your house more comfortable in every season.
Here are two reasons why you need effective attic insulation:
  •  Hot Air Rises. Most people know that to stay warm in cold weather, it’s important to wear a hat to prevent heat loss. Similarly, if your attic hasn’t got sufficient insulation, your house may be losing heat at a rapid rate. The hot air heated by your furnace is travelling up to the cold attic, where it cools rapidly, sinks back down, and has to be reheated. This forces more hot air up, where the cycle begins all over again. Or the warm air may simply be escaping out of the attic, and cold air finding its way in. Some experts estimate that 25% of the heating energy used by homeowners is due to improperly insulated and poorly sealed attics.
  •  Heat Radiates. In the summer, insufficiently insulated attics can get extremely hot. This pocket of very hot air can heat your ceilings and the whole structure of your house, forcing your air conditioner to work extra hard…and again, driving up energy bills. Lack of insulation and improper ventilation can also lead to mold problems that may damage any stored items and cause health problems.
Improving Energy Efficiency
The good news is that the attic is one of the easiest spots to add insulation. Making the effort to ensure that your attic is well insulated and sealed can make a tremendous difference to your energy bills, and can make your home much “greener.”
First, have an expert check for mold in the attic. Better insulation companies offer mold removal services. The process takes three or four days, and involves blasting mold from joists and sheeting, then applying an anti-microbial solution. Next, old insulation is extracted and the source of the mold is addressed. The following day, new insulation is installed.
There are several types of insulation commonly used in attics. The two most effective are:
  1. Blown Insulation. Cellulose blowing insulation is a fast and efficacious material for attics. Often the blown insulation consists of shredded newsprint that has been treated with an anti-fungal, fire retardant product. The paper is “fiberized,” a process that separates the individual cellulose wood fibers.
  2. Spray Foam Insulation. This type of insulation is very popular due to its efficiency, durability, and the ease of installation. It’s particularly suited for attic applications, since it easily adapts to irregular walls, corners, gaps, masonry ties, equipment penetrations, ductwork, and other types of non-uniform elements often found in attics and crawlspaces. It creates a seamless air barrier, greatly improving the attic’s energy efficiency. Better companies use eco-friendly, safe spray foam such as WALLTITE ECO.
