When working on a new home construction project, you need to be careful to follow federal, state and local energy codes. This includes codes concerning insulation. Codes for insulation usually include minimal requirements, but you should exceed those mandates to ensure your home is energy efficient.
To properly insulate this new home, the builder will determine where to insulate and the recommended R-values for each of those areas. The R-value is a measure of thermal resistance used in the building and construction industry. Under uniform conditions, it is the ratio of the temperature difference across an insulator and the heat flux, the rate of heat energy transfer through a given surface.
For this new home construction, the insulation was a blown in fiberglass product. Air vents and blockers were installed where needed as well as R-30 band board. This band joist is usually the same size as the floor joists and runs around the entire perimeter of the building.
We used R-23 BIBS blown fiberglass insulation in the side walls. BIBS® is a proprietary insulation system that blows dry white fiberglass insulation into walls, floors, attics and cathedral ceilings. The BIBS® system makes a custom filling around wiring and fixtures that eliminates costly voids and air gaps. BIBS® is an industry leader in new construction as well as retro fit projects.
In the ceiling, we used R-49 ISSP blown fiberglass. ISSP, or InsulSafe SP, is a fiberglass blowing insulation used in residential and commercial construction as a thermal and sound absorbing insulation. It is designed for pneumatic installation in open (attic) and closed (sidewalls and floors) construction cavities.
This level of insulation along with the geothermal heat will ensure this home has one of the most efficient heating and cooling system possible.
