Elastomeric Insulation R Value

They can be tested by the same methods as mass insulation and therefore assigned an r value.

Elastomeric insulation r value.

Cellulouse insulation has a r value rating of 3 6 4 0 cubic inches which is one of the highest ratings in the industry. Flexible elastomeric foams exhibit such a high resistance to the passage of water retarders that they do not. Along with knowing the r value of a particular insulation it is also important to calculate the r value of a total system. The elastomeric foam insulation prevents moisture and energy loss suitable for insulating hot and cold water services heating systems water lines air conditioning and refrigerator pipe frost protection and energy control.

As a benchmark one inch of solid wood has an r value of 1. The r value is the measurement of the resistance of building materials and structures to the flow of heat and sound. Elastomeric insulation is a type of closed cell foam insulation that s waterproof and an excellent insulation. 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.

It prevents moisture thus stops mold and mildew from forming. Notes to the table above. For example if you have a type of insulation that has an r value of r 5 per inch of thickness you will need a depth of 6 inches of this insulation installed in your attic to reach r 30 if you live in zones 2 or 3. Elastomeric foam insulation is a flexible closed cell foam based on nbr or epdm rubber.

Notes on the r value k values of different forms of asbestos. These r values are a sum meaning this should be the total r value once you add up the entire depth of insulation.
