Explaing Different Insulations

Insulation is essential for creating energy efficient homes. There are four types of insulation currently used in residential construction: loose fill, batts/blankets, rigid foam and spray foam.

Insulation types have varying levels of installation difficulty and efficiency. The appropriate insulation for a given application will vary by climate, budget and construction considerations. The recent introduction of "green" alternatives to traditional materials is another factor to consider.

Loose Fill Insulation

Loose fill insulation is created by blowing fibers or pellets of insulating material into home cavities. Loose fill insulation is generally more expensive than traditional blanket insulation, but loose fill is better at filling air gaps and odd-shaped spaces.

Fiberglass and rock wool (recovered from steel production) are used to create the majority of loose fill material. Environmentally conscious manufacturers have begun to use recycled newspaper to create cellulose material for loose fill insulation.

Batt/Blanket Insulation

Blanket insulation comes in rolls or precut lengths called "batts". Blanket insulation is created by placing a fibrous material between sheets of heavy backing material. Blanket insulation is inexpensive, but it must be installed correctly to ensure a good seal.

Blanket insulation is typically made of fiberglass or rock wool. Recently, recycled cotton material recovered from denim factories has been used to create blanket or batt insulation.

Rigid Board Foam Insulation

Rigid board foam insulation is created from fiberglass or polyurethane foam. Rigid foam insulation has a high R-value and is useful in low-clearance applications like flat roofs, basement walls and exposed ceilings.

Spray Foam Insulation

Spray foam insulation is an expanding adhesive foam sprayed through a nozzle into voids in walls, ceilings and floors. Once applied, spray foam hardens into a solid insulating material. Spray foam insulation is more expensive than blanket insulation, but it also creates an air barrier making it cost competitive.

Environmentally friendly soy foam has been used recently to replace polyurethane in spray foam installations.
