Dense Pack Wall Insulation

Some will drill a hole at the top but it is really of no consequence.

Dense pack wall insulation.

When evenly packed dense pack cellulose insulation effectively seals the whole cavity. 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 2005 metric homes of carp ontario designed and built canada s first energy star labelled home in canada. Dense pack places pressure on the cavity and should be done by an experienced installer.

Dense packed cellulose insulation the history.

This method stops the stack effect and convective loops in wall cavities. Dense packing the best insulating standards involve packing fiber material with a minimum of 3 5 psi. Cellulose is considered dense packed when it is around 3 6 lbs per cu ft. 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.

Their intent was to produce a better built home with the goal of creating a proper balance between additional efficiency and price such that it would be attractive to future clients. Typically a hole is drilled at the bottom of the wall cavity 1.
