Wall Fill Cellulose Insulation

Cellulose insulation is plant fiber used in wall and roof cavities to insulate draught proof and reduce free noise.

Wall fill cellulose insulation.

The word cellulose comes from the french word cellule for a living cell and glucose which is a sugar. Foam insulation may be made from polystyrene polyisocyanurate or polyurethane which are all types of plastic. 2 a structure insulated with r 13 fiberglass batts wall cavities and blown in loose fill insulation attic floor. Cellulose fiberglass and rock wool are typically blown in by experienced installers skilled at achieving the correct density and r values.

1 an uninsulated structure. Loose fill cellulose insulation can settle around and conform to most of the obstructions found in walls and attics. Cellulose insulation is made from recycled paper products. 2 as demonstrated by the large scale outdoor fire test program comparing.

Manufacturers also add borate for fire and insect resistance. Loose fill cellulose is relatively inexpensive yet still has an r value of about 3 5 per inch of thickness compared to fiberglass r value between r3 to r4 per inch. With boric acid added for fire resistance shredded recycled telephone books tax forms and newspapers all contribute to making safe cellulose insulation blown in cellulose is injected into the wall cavities by a series of holes drilled into either the inside or outside of the walls. When walls are already finished injecting loose fill cellulose insulation is one of the few ways of adding.

Cellulose insulation is used as a filler material to fill various cavities and spaces but cellulose insulation boards and mats are also produced. The thermal conductivity of cellulose insulation varies with temperature moisture content and mass density. Loose fill insulation can be installed in either enclosed cavities such as walls or unenclosed spaces such as attics. When you install loose fill insulation it s hard to miss a spot the way you might with batt insulation.

However like other loose fill insulation it also has a tendency to settle over time reducing its r value and its ability to prevent air movement. As a loose fill insulation cellulose provides high insulating values represented by its higher r value and it creates a good barrier against air leaks and infiltration. From the speed and ease of installation to the virtual impossibility of installing it wrong assuming you re experienced loose fill fiberglass or cellulose is usually more effective than batt insulation. Loose fill insulation is just better.

And 3 a structure insulated with greenfiber s cellulose insulation using spray applied cellulose insulation wall. Building insulation is low thermal conductivity material used to reduce building heat loss and gain and reduce noise transmission.
