Dense Packing a wall, ceiling or floor provide a superior insulation performance. The density helps eliminate leaks and better controls the loss of heat and cool.
Dense Packing Walls
Dense packing existing walls is a traditional, time-proven technique to increasing thermal performance. Retrofitting does not always involve removing the interior drywall/plaster. Drilling a hole in the exterior or interior and sending a tube into the cavity is the best way to minimize retrofit costs.
In recent years, it has become popular to dense pack walls in new construction. Before the drywall is placed, insulation contractors have an option to pack the exposed cavities by using a material like InsulWeb. This material is applied to the wall by stapling it every inch. This provides a strong barrier to receive the dense packing of 3.5 psi. The contractor has a very good view of the cavity and how it is filled. Some manufacturers have created certifications to install their products. We do not advocate one material company over another. However, there are no necessary qualifications necessary to install cellulose or fiberglass in this manner.More
