Morrison Insualtaion LLC
New Construction:
We offer and install both cellulose and fiberglass batts for newly framed walls...But Recommend Cellulose for your walls floors and attic.
The following is a summary of an extensive Natural Resources Defense Council (NRDC) report. The NRDC is a non-profit environmental membership organization with over 300,000 members and contributors nationwide:The NRDC has concluded the following:
Due to air circulation and natural convection, the R-value of blown-in fiberglass insulation decreases by as much as 50% as the temperature drops from 45 degrees F to 18 degrees F. Cellulose has better resistance to air flow and prevents the upward movement of air caused by temperature differences (the R-value of cellulose actually improves during cold weather). Cellulose insulation manufactured from recycled paper is the least polluting and most energy efficient insulation. Cellulose has the highest post-consumer recycled content. The fiberglass industry averages 35% recycled glass, while the cellulose industry averages a minimum of 75% recycled content.
It takes more than 10 times as much energy to produce fiberglass insulation as cellulose insulation. Substantial and well-documented public health threats are associated with fiberglass. No adverse health effects from cellulose insulation have been identified.

Will My Choice of Insulation Really Effect My Monthly
Heating & Cooling Bills?
YES!Sound Deadening:
Different insulations are made from fundamentally different materials. Tests at Oak Ridge and Brookhaven National Laboratories and the University of Illinois reveal that insulations with the same laboratory R-values do not perform equally in real homes. Researchers found that the effective R-value of blown fiberglass plunges during cold weather, while the effective R-value of cellulose actually increases. The researchers also discovered that summer temperatures offer no relief for fiberglass, since its effective R-value withers then, also.
We can also spray cellulose for sound control. This can be beneficial to separate different rooms. (Bathrooms, Master bedroom or media room) Or for partition walls between businesses such as shown here.

Cellulose is Much better for reducing sound between rooms or separate living units...Below is a comparison rating when used in a typical 2x4 wood framed wall.
More and better sound deadening can be achieved by using 2x6 framing or staggered framing members sprayed with Cellulose when there is need for
privacy.
