What are the different Types of Insulation?
There are various types of insulation commonly found in residential and commercial buildings. Insulation is used to make things airtight and save a person money on their energy bill. Walls, ceilings and floors that are well-insulated will keep cold drafts out during the wintertime, holding the heat in and causing lower energy bills. Different types of insulation also hold different R-values. R-values measure the effectiveness that any particular piece of insulation may have. This is based on the insulation’s thickness, material and density. The more effective a piece of insulation is, the higher its R-value will be. There are various types of insulation on the market, but the four most commonly used types of insulation are loose-fill insulation, blanket insulation, rigid board insulation and spray foam insulation. Loose-fill insulation is composed of loose fibers and fiber pellets that are blown into cavities or attics using special equipment. Loose-fill insulation is more costly, but
Whatever national standard regulation or region standard regulation, the standard of leakage current is different by the insulation types of products. “CLASSI, II, III” are mainly in consideration of the insulation system of product which derived from IEC system, brief descriptions are as below: • CLASS I indicates anti-shock protection of product not only depends on basic insulation but also includes grounding method. • CLASS II indicates anti-shock protection of product not only depends on basic insulation but also includes additional precaution. For example double or reinforce insulation but without grounding or installation condition for relying precaution. • CLASS III indicates anti-shock protection of product depends on power voltage is safety extra-low voltage (SELV) and it don’t generate danger voltage.
