We have done several real world and simulated tests and the application process has been perfected to reduce settlement to less than a credit card thickness. The cavities are not closed when the product is installed, we use an insulweb material to install the product then apply the exterior sheathing once complete visual inspection is completed.

Do you have documentation of cellulose settlement problems during transport?
The settled density of cellulose is 1.5 - 2.0 pcf. If it is blown into closed cavities at 3.0 - 3.5 pcf (which would be easier to monitor in a factory setting than on site), then it cannot possibly settle unless there was physical degradation of the fiber.

I do work with a modular manufacturer and have contacts with others. They have all stayed away from cellulose because of settlement during transportation. Does your group feel the dense-pack eliminates the risk of settlement by eliminating the space for settlement to occur??
