The importance of effective Attic Insulation & Attic Ventilation cannot be understated!

Your attic insulation, attic ventilation, and radiant heat is a major player in your home heating and cooling, which directly translates into your electric bill! Your attic has a few basic elements that can be improved to maximize energy savings.

  • Attic Insulation
  • Attic Ventilation

Energy loss from a home is inevitable. The forces of equilibrium, the physics of nature, continually strive to balance the heat energy on the inside, with that on the outside. Even in the best built houses, when the heating or cooling system goes OFF, the inside and outside temperatures immediately begin to equalize. Attic insulation helps to make energy loss from a home as slow as possible, to minimize the amount of time the heating or cooling system must be on to keep the temperature within a comfortable range. To help achieve this objective, attic insulation is used to control convection.


Having your home properly insulated can save an estimated 25-30% of the cooling and heating season energy costs. A major source of energy loss and infiltration occurs due to lack of proper insulation and your penetrations not being sealed properly. The Department of Energy recommends an insulation level of R-38 for our zone. This equates to roughly 15″ to 16″ of insulation in your attic.

Generally, if you can see the 2×4 or 2×6 beams of your attic floor, then you will need additional insulation. If you have fiberglass batts or rolls of insulation, bad news – you will need additional insulation as gaps may exist which reduces your R-Value.

Instead of laying batts or rolls, our AttiCat Insulation Blowing Machine conditions the AttiCat Expanding Blown-In PINK Fiberglas Insulation by fluffing it along the length of the hose, adding millions of the tiny air pockets that give the material its insulating power. Because Fiberglas insulation will not settle, it will maintain the same energy-saving level over time, keeping your home comfortable for years to come.


Attic ventilation is basically the flow of air through your attic. Your ventilation components (type) must provide for the adequate inflow of cooler outside air (soffit vent), and adequate outflow of your hotter attic air.

Ventilation of the home attic in a home in Knoxville, Tennessee is important for two reasons.

  • During the summer (especially in Tennessee), excess heat that builds up in the attic during the day results in high energy costs for cooling.
  • Moisture produced within the home may move into the attic if ceiling vapor barriers are not used. If this moisture is not exhausted from the attic, it can condense and cause insulation and construction materials to deteriorate and fail. (Insufficient moisture exhausting can also contribute to mold and mildew problems.)
