Are You Losing Money Through The Roof?

A study conducted by the University of Colorado School of Architecture shows that Cellulose insulation provides a more effective barrier against air infiltration than traditional insulation materials, one of the key factors in preventing energy loss.

In cold weather, research by the Oak Ridge Research laboratory shows that the effective R-value of fiberglass drops as the differential between indoor and outdoor temperatures gets larger.


Six inches of blown in Cellulose insulation is all it takes to prevent the loss of heat due to air convection versus fiberglass alone. Even if you have fiberglass installed in your attic, you can improve its performance by providing a “cap” of Cellulose insulation six inches deep, which will save you money on your utility bills.

    This information was very usefull, but is there anyone out there that can help me with a graph which shows your r-values at the bottom and then your heat loss percentage on the left hand side starting from 0% up to 100% I need it for a project that I’m working on.

  2. Thanks a lot for giving everyone a very memorable possiblity to discover important secrets with this site. It is usually and so beneficial and full of a great time for me and my office friends to go to your blog really thrice every week to see the new guides you may have.
