Dense Pack Cellulose Insulation Cathedral Ceiling

Advantages to dense packing.

Dense pack cellulose insulation cathedral ceiling.

There are several major advantages to dense packing completely filling a cathedral ceiling cavity with cellulose. First cellulose has a natural density about two times that of fiberglass batts and four to five times that of loose blown fiberglass. There will be plenty of insulation packed at the right density. In fact dense packing walls typically results in remarkable performance.

This makes it much more difficult for air to move through the insulation. You achieve the maximum insulating capacity. So bees ants and termites won t find that ceiling so inviting anymore. For a faster more affordable solution to the cathedral ceiling problem dense pack cellulose insulation can be blown into the ceiling s rafter bays through access points along the roof eaves or roof ridge.

It is the dense packing of unvented cathedral ceilings or unvented flat roofs that is the problem. At 3 5psi the insulation will not settle and create gaps. Cellulose is treated with borate a harmless naturally occurring mineral that has the ability to deter bugs. One of the most effective ways of dealing with existing uninsulated frame walls is to blow cellulose into the wall cavities.

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.
