The Three Primary Attic Insulation Types

January 31st, 2013

Most people lack the professional experience needed to truly understand the difference between many of the leading attic insulation types or the benefits of each. First and foremost, an insulated attic is the best means of protection against heat loss and can help the average homeowner to drastically reduce their energy expenses; energy conservation is a widely realized necessity in modern times. Attic insulation that is properly fitted from a reputable technician, like those at Attic Plus, is a cost effective solution to the growing concern of rising utility bills – especially for homeowners on a budget and unable (or unwilling) to fit their homes with brand new energy efficient appliances. The Best Attic Insulation Types Prevent Warm Air From Escaping The laws of physics dictate that warm air will always travel upwards. For this purpose, it is essential that a home’s attic be properly insulated. In the event that a home lacks the proper insulation, warm air will travel upward and leak through window frames and crevices in the rooftop. Furthermore, homes that are not adequately insulated often require extensive and ongoing furnace maintenance and repair since the furnace is required to run harder and longer in order to heat the home. What Types of Attic Insulation is Best?  The three primary types of attic insulation are:
  1. Fiberglass Batt Insulation: The most widely marketed type of insulation, fibreglass batt insulation is what most people think of when they hear the word insulation. This type of insulation is typically pink and comes in different R-values.
  2. Cellulose Attic Insulation: This form of insulation is far less costly than fibreglass batts, however, it is not as easy to install. Cellulose insulation is a loose fibre like material that is blown into the attic and each hand every crevice or hole, resulting in a uniform and air tight seal.
  3. Spray Foam Insulation: This attic insulation type is most often used in commercial settings. Since the spray material expands it is possible to obtain maximum coverage in even the most difficult to reach areas. Furthermore, spray foam insulation has some of the highest r-values available.
Properly installed attic insulation is extremely effective at reducing energy consumption and cost. In fact, most of the leading insulation (when installed by a professional) presents homeowners with the potential to reduce their energy costs by as much as 30%.
