Dense Pack Wall Insulation

Dense packing the best insulating standards involve packing fiber material with a minimum of 3 5 psi.

Dense pack wall insulation.

Cellulose is considered dense packed when it is around 3 6 lbs per cu ft. This method stops the stack effect and convective loops in wall cavities. Aroostook dense pack wall insulation when cellulose is pneumatically installed at high velocity to densities greater than 3 5 pounds per square foot it acquires a unique air sealing property. Dense packed cellulose insulation the history.

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. In this process the material behaves as a liquid flowing into obscure bypasses and solidifying them. 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. The home performance industry and its accrediting bodies support the dense pack standard of insulating wall cavities which does not settle.

Dense pack places pressure on the cavity and should be done by an experienced installer. Typically a hole is drilled at the bottom of the wall cavity 1. This home was built with dense packed or dense blown cellulose as the wall insulation of choice. In 2005 metric homes of carp ontario designed and built canada s first energy star labelled home in canada.

When evenly packed dense pack cellulose insulation effectively seals the whole cavity. Some will drill a hole at the top but it is really of no consequence.
