How Can I Tell If I Have Enough Attic Insulation?
One quick way to determine if you need more is to look across the span of your attic. If your insulation is just level with or below your floor joists (i.e., you can easily see your joists), you should add more. The current code of R-38 recommends that you have about 13.8 inches of insulation. Energy Star, however, recommends an R-49 for our area.
Ask yourself these simple questions:
- Does my insulation cover my attic evenly?
- Can I see exposed rafters?
- Is there any exposed sheet rock?
If you answered yes to any of these questions, your attic could use more insulation. Our modern insulation materials will give you a maintenance (and worry!) free attic. One that will keep your home energy-efficient and comfortable. Current minimum building standards require that an insulation value of R-38 be installed in all new homes. The US Department of Energy, however, recommends a min of an R-49 to ensure optimal energy efficiency in our climate.
What type of insulation is best?
We use high-quality blow in loose-fill fiberglass insulation for most of our attic insulation jobs because it helps keep our client’s cost down. Benefits also include the fact that it doesn’t settle like cellulose insulation. Not every attic is the same, some are best to insulate with batts. Other attics require polyiso foam board (like RMAX ridged foam) and others require a dense pack product like JM Spider or Knauf Jet Stream. As with each aspect of our company, we want to do what is best for our client. This is so if you need another job done, we can help with it. Wonder what would be best for your home?

Fiberglass is made of recycled glass and silica. It is then spun into fibers. The tiny air spaces help to slow down the transfer of heat. The resistance to the transfer of heat is called the “R” value. The higher the R-value, the higher its resistance to the transfer of heat. Fiberglass can be blown in or laid down in pre-made batts, depending on the space needing to be insulated. Our fiberglass attic insulation is formaldehyde-free, uses only a vegetable binding agent and is a great green insulating solution. Even though it is a little more expensive than cellulose insulation we use fiberglass because it is a natural fire retardant.
