Blocking an Open Crawl Space with Cellulose Insulation - www.startinsulating.com

In this property a drop ceiling was installed when the home was converted from a single-family to a two-family residence. This is commonly done to conceal ceiling damage, but also to run separate electrical and pluming lines to the upper unit.

During the installation of the drop ceiling the upper part of the lath and plaster walls were damaged and/or removed. As a result, it would have been impossible to dense-pack the walls with cellulose without the cellulose being forced into the narrow drop ceiling area.

To properly insulate this home and dense-pack the walls with cellulose a large bag was sewn and placed against the exterior wall. Cellulose insulation was then blown into the bag to expand it and create a barrier against the open wall cavities. Though the bag does not create a perfect block, it created the barrier needed to allow the cellulose to back up and pack to approximately 4.0 pounds per cubic foot in the exterior walls.
