I was very surprised by your comment that there was very little fiber dust when blowing this insulation. When we blow cellulose there seems to be an abundance of dust from the product. We are not operating the equipment at high speeds or anything and are using a 4" delivery hose.Insulation Dallas

Some fiber insulation materials are dusty, others, including many cellulose products, produce virtually no dust during installation. Apparently the cellulose insulation installed in Mr. Doyle's office was a low dust material.

We did quite a bit of preparation for the installation as noted in the story including sealing off the room with the attic access. The attic access was in a bathroom which made controlling dust easier as well. Prior to starting the blower the shower was run which added moisture to the area to help collect dust. The insulation was also blown with a slight bit of moisture added to help control dust as well. The window in the bathroom was also open with the screen removed to aid in ventilating.
The end process was a very low level of dust in the bathroom which was easily cleaned up. The remainder of the house was virtually dust-free.
Thanks for your comment.

Hi Insulation Dallas:
Cellulose can be dusty, but it looks like these contractors were careful to minimize the dust in the house.
For those who have dust issues with cellulose, there are at least two other ways to minimize the dust:
First, make sure that you are not using stabilized cellulose that is designed for wall spray. It includes a starch that will create a lot of dust in an open, dry blow situation.
Second, many installers are using an internal wetting system for insulation blowers
. This adds a mist of water to the material which controls the dust in the attic and creates a nice stabilized crust after it dries.

Good comments and suggestions Barry. That is pretty much what my insulation contractor did. In Florida we always have concerns with moisture due to the humidity. However, my project was done in the dry winter season and it has set up nicely--high and dry in the attic.
