Types of insulation categorization of insulation materials.
Types of insulation material.
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.
Insulation decreases the amount of heat entering from outside when it s hot and traps warmth inside when it s cold.
For insulation materials three general categories can be defined.
Typical values are approximations based on the average of available figures.
Rsi values and r values for various materials normalised to a one inch 25 4 mm thickness.
Insulation is rated by its r value.
One type of cementitious spray foam insulation known as air krete contains magnesium silicate and has an initial consistency similar to shaving cream.
All of these materials are produced using recycled waste materials.
R value measures how resistant types of insulation are to heat flow.
In practice the values will have been obtained using different methods and thicknesses.
Mineral wool is usually produced.
The last column gives rsi values normalised to a metre thickness.
The most common types of materials used for loose fill insulation include cellulose fiberglass and mineral rock or slag wool.
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.
Most fiberglass products contain 40 to 60 recycled glass.
The more costly xeps has a r value of r 5 5 while eps is r 4.
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.
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.
It comes in two types expanded eps and extruded xeps also known as styrofoam.
Air krete is pumped into closed cavities.
Cellulose is primarily made from recycled newsprint.
