Types Of Insulation Material

Building insulation materials are the building materials which form the thermal envelope of a building or otherwise reduce heat transfer.

Types of insulation material.

The most common types of materials used for loose fill insulation include cellulose fiberglass and mineral rock or slag wool. The two types differ in performance ratings and cost. 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. 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.

Rsi values and r values for various materials normalised to a one inch 25 4 mm thickness. In practice the values will have been obtained using different methods and thicknesses. For insulation materials three general categories can be defined. The last column gives rsi values normalised to a metre thickness.

One type of cementitious spray foam insulation known as air krete contains magnesium silicate and has an initial consistency similar to shaving cream. Cementitious insulation material is a cement based foam used as sprayed foam or foamed in placed insulation. 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. Polystyrene is a waterproof thermoplastic foam which is an excellent sound and temperature insulation material.

These categories are based on the chemical composition of the base material from which the insulating material is produced. Air krete is pumped into closed cavities. The more costly xeps has a r value of r 5 5 while eps is r 4. R value measures how resistant types of insulation are to heat flow.

It comes in two types expanded eps and extruded xeps also known as styrofoam. Insulation is rated by its r value. Insulation decreases the amount of heat entering from outside when it s hot and traps warmth inside when it s cold. Types of insulation categorization of insulation materials.

Cellulose is primarily made from recycled newsprint. Typical values are approximations based on the average of available figures. R values vary based on the type thickness and density of the insulation material.
