Loose fill blown fiberglass can be blown over attic ceilings
creating a much more energy efficient and comfortable occupied
space. This product can be applied in both residential and
commercial structures. Blown fiberglass is an effective yet cost
efficient solution to high energy bills. Blown fiberglass has a
R-value of 2.4 per inch. Typically, we apply between 12 and 15
inches to an attic ceiling totaling R-30 to R-38 pending the needs
of the structure and local government regulations. It is
recommended that attics be re-blown with fiberglass every 10 to 12
years as the product settles over time. A decrease in R-value and
affectivity with progression of life cycle is expected.
Spray applied radiant barrier paint is applied to the underside
of roof decking and gable walls in most cases. As long as there is
a 2" air gap between the bottom side of the radiant barrier it will
consistently deflect solar heat gain. By deflecting the radiant /
solar heat at the roof deck we ensure a cooler attic assembly.
Typically, attic temperature should be close or below exterior
temperature. It is also important to note, when applying radiant
barrier, the existing fiberglass will be walked down by the
installers. Every radiant barrier application should be followed
with a fiberglass re-blow to ensure uniform R-Value at the ceiling
of the attic assembly.
