Different Types Of Attic Insulation

Depending on what the season is, your attic is majorly responsible for letting heat and cold into your house thereby increasing your power bills. Thus it is vital you acquaint yourself with the best and the most popular among the attic insulation methods available.

The following classification is meant to give you an idea of what these are.


  • Batts Insulation – Cotton and fiberglass are the materials required here. Long fibers of glass crisscross into a stitch pattern bound by strong glue to form the main batts insulation material although cotton batts are used too in the form of recycled, worn out clothing material. But batts are a defective choice given they do not insulate fully and leave empty spaces and incompletely filled gaps.
  •  Blown in insulation – Most attics are initially insulated by smaller blown in bits of cellulose since this is a very cost effective method. This is a much more useful way of preventing heat and cold from getting in than the batts method since the chunks of insulating substance are hosed in with the help of sophisticated machinery and the smaller sized bits ensure that the number of unfillable empty spaces are reduced. But cellulose has a lower thermal resistance and also leads to other hazards by soaking up excessive moisture.
  •   Spray foam insulation – The last method or spray foaming is the being steadily designated as the best method to insulate your attic. Spray Foam Attic Insulation2 types of spray foam methods are generally available – the more advantageous closed cell and the less useful open cell. Open cell spray foam ensures a lesser form of thermal insulation with its resistance of about 3.2 per inch while closed cell foam is known to have an R value of up to 7 per inch. While open cell consists of interlocked cells where the walls are not sealed, thereby allowing water vapor to get in, closed cell consists of gas bubbles with completely sealed off walls which act as barriers against the entry of moisture. Most preferable method of spray foaming the attic is to coat the surface of the roof with the spray foam material while selecting loose fill insulation to apply on the surface exposed to the elements. Another genuine utility of using spray foam is that it is possible to bring all the ducts and vents of our house within the envelope of the foam if you are using insulation for the first time. You do not need to change the basic design of your home. Spray foam costs significantly higher than other forms of insulation but it is the most headache-free solution to your attic insulation problems.
