dense-pack insulation help

Dense pack cellulose is used more commonly today for adding retrofit insulation. The dense packing into the wall cavities adds a thermal insulation while providing some level of sound proofing. Wet spray cellulose has water added to it during the application process. The material has the same thermal and sound retardant properties as dense packing, according to the blog.

2018-7-26 · I can see how it doesn’t exactly look like a vapor barrier in the diagram as it is black, but it is one. What you see on the interior of that diagram is the netting that holds the cellulose in place while allowing air to escape during injection, followed by a poly vapor barrier, strapping and drywall.And to be clear, you absolutely need a vapor control layer of some kind on the warm side of ...


With a process called dense packing, cellulose insulation is pneumatically installed at high velocity to densities greater than 3.5 pounds per cubic foot, it acquires a unique air sealing property. In this process, the material behaves as a liquid, flowing into obscure bypasses and solidifying them. Dense Packing (DP) solves air movement ...


2021-8-1 · Dense-pack methods have the advantages of preventing insulation from settling, completely filling the cavities, consistent insulating values, and the ability to slow airflow. Cellulose is the favored type of dense-pack insulation used for the DOE-funded low-income weatherization programs.


2011-10-1 · When evenly packed, dense pack cellulose insulation effectively seals the whole cavity. Cellulose is considered dense packed when it is around 3.6 lbs per cu ft. Dense packed cellulose insulation provides excellent thermal resistance (an R-value of 3.0-3.5 per inch), sound proofs the wall and greatly retards air flow. Important Note!
