Types of insulation categorization of insulation materials.
Types of insulation material.
Insulation is rated by its r value.
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.
Typical values are approximations based on the average of available figures.
Building insulation materials are the building materials which form the thermal envelope of a building or otherwise reduce heat transfer.
These categories are based on the chemical composition of the base material from which the insulating material is produced.
In practice the values will have been obtained using different methods and thicknesses.
All of these materials are produced using recycled waste materials.
Insulation decreases the amount of heat entering from outside when it s hot and traps warmth inside when it s cold.
The most common types of materials used for loose fill insulation include cellulose fiberglass and mineral rock or slag wool.
Most fiberglass products contain 40 to 60 recycled glass.
Cellulose is primarily made from recycled newsprint.
R values vary based on the type thickness and density of the insulation material.
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.
Rsi values and r values for various materials normalised to a one inch 25 4 mm thickness.
Air krete is pumped into closed cavities.
One type of cementitious spray foam insulation known as air krete contains magnesium silicate and has an initial consistency similar to shaving cream.
The last column gives rsi values normalised to a metre thickness.
The two types differ in performance ratings and cost.
Mineral wool is usually produced.
For insulation materials three general categories can be defined.
Cementitious insulation material is a cement based foam used as sprayed foam or foamed in placed insulation.
