Elastomeric Insulation R Value

Rosato asbestos insulation is the most authoritative source on asbestos properties and gives data for the thermal conductivity of asbestos in different forms and with varying temperatures for magnesia asbestos insulation at mean temperatures ranging from 100 f to 400 f the k value thermal.

Elastomeric insulation r value.

Flexible elastomeric foams exhibit such a high resistance to the passage of water retarders that they do not. They can be tested by the same methods as mass insulation and therefore assigned an r value. In comparison an inch of blown fiberglass insulation has an r value of 3 1 3 4 and an inch of blown cellulose in an attic has an r value of 3 2 3 7. Notes to the table above.

Elastomeric insulation is a type of closed cell foam insulation that s waterproof and an excellent insulation. The r value is the measurement of the resistance of building materials and structures to the flow of heat and sound. These r values are a sum meaning this should be the total r value once you add up the entire depth of insulation. Elastomeric foam insulation is a flexible closed cell foam based on nbr or epdm rubber.

Cellulouse insulation has a r value rating of 3 6 4 0 cubic inches which is one of the highest ratings in the industry. This means higher thermal performance for your home or business. As a benchmark one inch of solid wood has an r value of 1. Notes on the r value k values of different forms of asbestos.

Along with knowing the r value of a particular insulation it is also important to calculate the r value of a total system. Reflective insulations retard the transfer of heat.
