Elastomeric Insulation R Value

Elastomeric insulation is a type of closed cell foam insulation that s waterproof and an excellent insulation.

Elastomeric insulation r value.

These r values are a sum meaning this should be the total r value once you add up the entire depth of insulation. It prevents moisture thus stops mold and mildew from forming. 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.

Cellulouse insulation has a r value rating of 3 6 4 0 cubic inches which is one of the highest ratings in the industry. 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. 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.

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. Flexible elastomeric foams exhibit such a high resistance to the passage of water retarders that they do not. This means higher thermal performance for your home or business. Notes on the r value k values of different forms of asbestos.

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.
