Dense Pack Cellulose Insulation Cathedral Ceiling

Advantages to dense packing.

Dense pack cellulose insulation cathedral ceiling. First the good stuff. In fact dense packing walls typically results in remarkable performance. Cellulose is treated with borate a harmless naturally occurring mineral that has the ability to deter bugs. It is the dense packing of unvented cathedral ceilings or unvented flat roofs that is the problem.

Energy saver suggests dense packing cellulose to insulate this cathedral ceiling where air flow will now be interrupted and insects and pests will be unlikely inhabitants. There will be plenty of insulation packed at the right density. There are several major advantages to dense packing completely filling a cathedral ceiling cavity with cellulose. This makes it much more difficult for air to move through the insulation.

At 3 5psi the insulation will not settle and create gaps. So bees ants and termites won t find that ceiling so inviting anymore. By filling the entire cavity with a dense pack you get the highest insulation ratings fiberglass or cellulose can achieve. One of the most effective ways of dealing with existing uninsulated frame walls is to blow cellulose into the wall cavities.

The insulation will continue to keep the cavity filled.
