Types Of Insulation Material

Insulation is rated by its r value.

Types of insulation material.

Most fiberglass products contain 40 to 60 recycled glass. Cellulose is primarily made from recycled newsprint. Insulation decreases the amount of heat entering from outside when it s hot and traps warmth inside when it s cold. Typical values are approximations based on the average of available figures.

One type of cementitious spray foam insulation known as air krete contains magnesium silicate and has an initial consistency similar to shaving cream. Polystyrene is a waterproof thermoplastic foam which is an excellent sound and temperature insulation material. Cementitious insulation material is a cement based foam used as sprayed foam or foamed in placed insulation. Building insulation materials are the building materials which form the thermal envelope of a building or otherwise reduce heat transfer.

Installing this type of insulation is an inexpensive and diy friendly project since the materials are designed to fit into the standard width between wall studs attic rafters and floor joists. In practice the values will have been obtained using different methods and thicknesses. Insulation may be categorized by its composition natural or synthetic materials form batts blankets loose fill spray foam and panels structural contribution insulating concrete forms structured panels and straw bales functional mode. All of these materials are produced using recycled waste materials.

Rsi values and r values for various materials normalised to a one inch 25 4 mm thickness. The most common types of materials used for loose fill insulation include cellulose fiberglass and mineral rock or slag wool. R values vary based on the type thickness and density of the insulation material. As was written thermal insulation is based on the use of substances with very low thermal conductivity these materials are known as insulation materials common insulation materials are wool fiberglass rock wool polystyrene polyurethane and goose feather etc.

The more costly xeps has a r value of r 5 5 while eps is r 4. Mineral wool is usually produced. The two types differ in performance ratings and cost. Types of insulation categorization of insulation materials.

For insulation materials three general categories can be defined. The last column gives rsi values normalised to a metre thickness. Air krete is pumped into closed cavities.
