Cellulose Insulation for your Attic

Adding attic insulation can also help to keep your home warm in the winter and cool in the summer, while saving you money on energy costs.

This is part of our process to protect and maintain the thermal boundary of your home; separating the conditioned space (living area that you want to keep heated and cooled) from the unconditioned space.

Many homes have inadequate insulation—often none at all, in older homes! Or, your attic may be insulated with fiberglass that is doing a poor job. If needed, cellulose can be easily applied over existing insulation. Researchers at Oak Ridge National Laboratories found that capping loose-fill fiberglass insulation with cellulose not only adds R-value, it actually restores the effective R-value that fiberglass insulation loses during cold weather.

Current Connecticut building codes require a minimum R-Value of 38 in an attic. You can upgrade to a R38 or the maximum recommended by the Department of Energy, which is R49.

When cellulose is blown into your attic, we can install the correct amount of insulation to achieve the desired R-Value, rather than trying to force a pre-formed fiberglass batt into a restricted, or oddly shaped space. Researchers of the University of Colorado School of Architecture and Planning have concluded that cellulose performs as much as 38% better than fiberglass.

Features of cellulose insulation:

  • Made of up to 85% recycled paper
  • Class 1, Type A Building Material – Fire Retardant
  • Part of the Energy Star home sealing program
  • Meets ASTM C739 standard for sound barriers
