How Attic Insulation Works

A quick tutorial in attic insulation.

Having inadequate attic insulation can have a tremendous impact on your heating and cooling bills. Your attic is the most important place in your home to have the correct amount and type of insulation. By having proper attic insulation installed, you can easily reduce energy costs and improve air conditioning and heating efficiency. But first, it's important to know the basics about the types of insulation that are available on the market and how they work in your attic to keep your whole home's temperature regulated. Below is a quick tutorial in how attic insulation works.


When researching a type of insulation, one of the most important things to note is its R-value, which is the measure of the insulation's heat resistance. The higher the R-value, the more effective it is at insulating your home. The R-value you need to shoot for when choosing insulation depends on the climate where you live.

Forms of Insulation

Insulation most often comes in the form of rolls, rigid boards, spray foam, or loose-fill. Most people are able to install rolls or boards of insulation themselves, while spray foam and blown-in loose-fill insulation must be installed by a professional. All types of insulation should be installed according to the manufacturer's specifications so that the product does a good job of trapping your home's heated or cooled air.

Air Leak Sealing

An important step to address before installing insulation is to locate and seal air leaks. Cracks between your living space and attic, between the attic and roof, and spaces around doors and windows can allow undesirable air flows that negate all the hard work of your HVAC systems. Sealing air leaks before installing new attic insulation will help your insulation keep your indoor air temperature regulated much more efficiently.

Comfort Services can provide you with the latest in attic insulation technologies through the use of the Owens-Corning AttiCat insulation system, which is a new fiberglass insulation that is dust-free and non-irritating to the touch. AttiCat fiberglass will not settle in your attic, which means that it will retain its R-value over time. This insulation can save you big money on your energy bill, and it is an ecologically sound choice because it is made using renewable resources that are plentiful and widely available, such as sand and recycled glass.
