USA: Roof Insulation Manufacturers
ABOUT ROOF INSULATION
Roof insulation, sometimes known as attic insulation, is usually applied to the floor of an attic, to reduce heat loss. It is the single quickest and cheapest way to reduce energy consumption in a dwelling. Roof insulation may be applied in three forms: as rolls, as flat batts, or as blow-in roof insulation.
Rolls and batts for roof insulation may be made from mineral wool or glass fiber. Blow-in roof insulation, sometimes known as loose fill roof insulation is normally made of fiber glass or cellulose. Cellulose blow-in roof insulation may be made from 80% recycled newspaper, chopped into small pieces. An advantage of blow-in roof insulation is that it can be easily applied right into the corner of the roof, and into narrow and difficult to reach parts of the roof.
It is necessary to take health precautions when handling fiber products such as mineral wool. It is possible to absorb fibers into the body through inhalation; there is also risk of irritating the skin and eyes.
