R-Value is the measure of the ability of insulation material to resist heat transfer. The R-Value is determined by placing carefully prepared test specimens between two plates in a laboratory apparatus and measuring heat flow through the insulation.
R-Value is a very accurate and reliable expression of how insulation materials perform with regard to conduction of energy in a laboratory apparatus. But people don't live in laboratories or only deal with the conduction of energy. They live in homes with real walls and ceilings, and in the real world of buildings R-Value is only one factor which determines the actual performance of insulated building assemblies.
We can do JetStream eco Blow in fiberglass or Ecotouch fiberglass
But we recomend to use cellulose.
Cellulose. It has a higher R-value per inch: 3.8 vs. 2.2 for most blown fiberglass. This is especially important over the top plates of the exterior walls.
Many truss systems will not allow a full 18 inches of insulation over these areas. We only need 13.3 ” to achieve R-50. Cellulose is a denser material as well, so it resists air movement better in the attic, just as it does in sidewalls.
We can refer you to a Energy Star Homes representative to help you with the program.
Mold spores are everywhere. They need moisture and a food source to grow and reproduce. Ninety-nine percent of all molds are considered harmless. In fact much of the mold frenzy, at the moment, is overblown. Nonetheless, it is still prudent to reduce the possibility of mold growth. We can help. Here’s how:
- First, the cellulose product we use is treated with a 100% borate solution (completely non-toxic) which is highly resistant to fungal growth.
- Second, the high density of the product and the fact that it seals the wall cavity so well minimizes the moisture in a wall system. Air movement is the primary transport mechanism for water vapor. Stop air movement in a wall cavity and you stop water vapor from entering the cavity as well, greatly reducing the potential for mold growth.
