How do I calculate how much insulation I need?

To calculate insulation needs, measure the square footage of the area to be insulated and consider the recommended R-value for your climate zone. Our insulation calculator simplifies this process by doing the math for you.

What's the difference between spray foam and blown-in insulation?

Spray foam insulation provides superior air sealing and higher R-value per inch but costs more. Blown-in insulation is more affordable and easier to install in existing walls and attics, though it may settle over time.

How much does attic insulation cost?

Attic insulation costs vary by material and region. Fiberglass batts typically cost $0.30-$1.50 per square foot, while spray foam can cost $1.50-$3.50 per square foot. Use our attic insulation cost calculator for precise estimates.

Types of Insulation Explained

Spray Foam Insulation

Spray foam provides excellent air sealing and high R-value per inch. Ideal for irregular spaces and areas where air leakage is a concern. Use our spray foam insulation cost calculator for precise estimates.

Blown-In Insulation

Perfect for retrofitting existing walls and attics. Our blown insulation calculator helps determine how much material you'll need based on square footage and desired R-value.

Attic Insulation

Proper attic insulation can significantly reduce energy costs. Try our attic insulation calculator to determine the optimal amount for your climate zone.

Crawl Space Encapsulation

Our crawl space encapsulation cost calculator helps estimate this specialized insulation method that prevents moisture issues and improves energy efficiency.

Why Proper Insulation Matters:

Reduces energy bills by maintaining consistent temperatures
Improves home comfort by eliminating drafts
Prevents moisture problems that can lead to mold
Increases property value with better energy efficiency
Reduces environmental impact by lowering energy consumption
