Blown-in Attic Insulation

Adding insulation to your attic is one of the fastest and most cost-effective ways to reduce energy waste and maximize your energy dollars.

By air sealing, adding insulation, and preventing the outside elements from intruding into your home, both your heating and your cooling systems will have to work a lot less to produce the same results.

In most homes, the attic is the hottest part of the house during the summer. Without adequate insulation, the extreme heat generated there transfers into the living space of the home and increases the demand on the air conditioning system. During the winter, inadequate insulation in the attic can cause heat loss and overwork the heating system. Properly air sealing and insulating your attic with cellulose insulation reduces the rate of heat transfer and stretches your energy dollars.

According to the US Department of Energy, up to 45% of a home's energy loss is through the attic, but the amount of heat actually lost will depend on where you live and how cold your attic gets. Therefore, homes in colder climates require higher insulation values. Recommended attic insulation levels range from R19 in the southernmost parts of the US to R49 in the northernmost.

With an R-Value of 3.8 per inch, cellulose insulation has very good resistance to heat, more than blown-in fiberglass. Cellulose insulation is manufactured from recycled paper and is the least polluting and most energy-efficient insulation for attics. Blown-in cellulose takes less energy to make than any other insulation material. Fiberglass insulation has up to 10 times more embodied energy than cellulose and is not typically recycled.

Cellulose has better resistance to airflow than fiberglass and prevents the upward movement of air caused by temperature differences (the R-value of cellulose actually improves during cold weather).

Seal Right's blown-in cellulose insulation is treated so that it has a class one fire rating (The highest any building material can receive). The cellulose also provides superior protection against mold and pests.
