How Much Does Spray Foam Insulation Cost?



Spray Foam Insulation Cost Spray Foam Insider


The cost of spray foam insulation material varies among manufactures. In general, spray foam insulation materials are sold in 55-gallon drums in two components: part A and part B. This is typically referred to as "a set of foam" and is sold by the pound in different densities. Common densities are 2 and 3 pound closed cell spray foam insulation and ½ - lb open cell spray foam insulation, depending upon the chemical manufacture's or supplier's pricing, R-values, and expected product yield. R-values can range from 3.5 per 1-inch to 7 per square foot, per 1-inch. Product yields are estimated at, or slightly above, 4,000 square foot, if it is sprayed at a thickness of one inch. A set (parts A & B) of 2-lb close cell spray foam insulation can cost roughly $2,000. Actual prices vary by manufacture or location.


The following are examples to assist buyers in calculating material costs:


Example 1:

A 2-lb spray foam insulation set = $2,000.00. Take 2,000 and divide it by 4,000 square feet (sprayed at 1-inch thickness) = 50 cents per square foot/inch (raw material cost).


Example 2:

A 3-lb spray foam insulation set. The yield is 3,000 square feet, sprayed at 1-inch thickness, and an R-value of 7. 2,000 divided by 3,000 square feet, assumed sprayed at 1-inch thickness = 67 cents per square foot/inch (raw material cost).


Example 3:

A ½-lb open cell spray foam insulation: Open cell spray foam insulation yields range approximately 15,000 per square foot, sprayed at 1-inch thick. R-values vary between 3.5 to 4.8 per 1-inches. 2,000 divided by 15,000 = 13 cents per square foot/inch (raw material cost).
