Spray foam insulation cost:

Spray foam insulation cost in League City, Texas ranges from $1,800 to $4,600 (coverage area of 1,000-sf with 3-inches of insulation). Prices vary based on the type of insulation installed. Open cell insulation is less expensive (lower end of range) and closed cell insulation is more expensive (upper end of range). Keep in mind that open cell foam insulation has a lower R-value than closed cell. Closed cell foam insulation is about twice as energy efficient per inch (which is one of the reasons it is more expensive). However, open cell insulation is a much more efficient sound barrier. Consult with a contractor to discuss the benefits of each type.

Spray foam insulation cost (closed cell foam insulation):

Closed cell spray foam insulation in League City, Texas ranges from $1.00 to $1.50 per board foot. Each sprayed layer expands to about one inch (R-value of around 7). Exterior walls may need up to 3-inches of closed cell insulation (which has an R-value of about 21) and attics typically need 3-inches (R-value of 21) to 5-inches (R-value of 35). Colder environments may require additional layers in the attic and moderate climates may require fewer.
Definition of Board Feet: The term board feet refers to a 1-foot (length) x 1-foot (width) x 1-inch (height) of insulation. If you wanted to spray 3-inches of insulation onto a 20-ft by 50-ft attic roof, the calculation would be 20 x 50 x 3 = 3,000 board feet. Another way of saying it is that 1,000-sf area with 3-inches of insulation = 3,000 board feet.

Spray insulation cost (closed cell insulation) based on the number of board feet:

Closed cell spray insulation cost for 3,000-bf (1,000-sf with 3-inch insulation): $3,100 to $4,600.
Closed cell spray insulation cost for 4,500-bf (1,500-sf with 3-inch insulation): $4,600 to $6,900.
Closed cell spray insulation cost for 6,000-bf (2,000-sf with 3-inch insulation): $6,100 to $9,200.
Closed cell spray insulation cost for 7,500-bf (2,500-sf with 3-inch insulation): $7,700 to $11,500.
Closed cell spray insulation cost for 9,000-bf (3,000-sf with 3-inch insulation): $9,200 to $13,800.

Foam insulation cost (open cell spray foam insulation):

Open cell spray foam insulation ranges from $0.60 to $0.90 per board foot. This type of insulation typically expands to about 3-inches per layer. Most commonly, it has an R-value of 3.5 to 3.6 per inch which means a 3-inch layer has an R-value of approximately 10.5 to 11. Since open cell foam expands to about 3-inches, only one application of open cell can be used in walls (which means the max R-value of the wall will be around 11). In attics, there is often enough room to apply two layers (around 6-inches), which would increase the R-value to around 22.

Foam insulation cost (open cell insulation) based on the number of board feet:

Open cell foam insulation cost for 3,000-bf (1,000-sf with 3-inch insulation): $1,800 to $2,800.
Open cell foam insulation cost for 4,500-bf (1,500-sf with 3-inch insulation): $2,800 to $4,100.
Open cell foam insulation cost for 6,000-bf (2,000-sf with 3-inch insulation): $3,700 to $5,500.
Open cell foam insulation cost for 7,500-bf (2,500-sf with 3-inch insulation): $4,600 to $6,900.
Open cell foam insulation cost for 9,000-bf (3,000-sf with 3-inch insulation): $5,500 to $8,300.
