Starr Homes is known for building energy efficient custom homes. There are many steps that make energy-efficient designs possible.  When it comes to insulating the home, Starr Homes utilizes enhanced methods to offer a better insulation package.


Before adding insulation, the 2x6 construction of a Starr home is caulked and sealed to reduce air leakage and moisture. When the home is ready to be insulated, a netting material is placed over and stapled to the 2x6's. The netting ensures the insulation will be contained and packed tightly into the wall cavities. After the exterior walls are sealed with netting, the insulation will be blown in.

Blown Insulation

In most code-built homes, insulation is rolled into the wall cavities from large sheets between the 2x4 construction. However, a Starr home uses blown insulation and thicker exterior walls. The better quality insulation fills more gaps and seals tighter than traditional rolled fiberglass, and the extra 2 inches of insulation boosts the R-value.


The R-value refers to the capacity of a material to resist the flow of heat. A higher R-value translates to better insulating opportunities. This means a home that has a higher R-value on the perimeter walls will remain warmer in the winter and cooler in the summer. 

Trust the numbers:

  • On average: Rolled fiberglass insulation has an R-value of  13
  • Blown insulation in 2x4 constructions has an average R-value of  19
  • 2x6 construction with blown insulation has an average R-value of  22
