Whether you need a small upgrade or a large-scale insulation project, Merk Spray Foam has the expertise and equipment to get the job done right.
We provide both closed-cell and open-cell spray foam insulation for residential, agricultural, and commercial customers throughout Eastern Iowa. Closed-cell spray foam is dense, highly energy efficient, and ideal for applications like attics, crawl spaces, basements, and pole barns where maximum insulation performance is needed. Open-cell spray foam, which is lighter and more flexible, is commonly used for interior walls and flat ceilings to improve comfort and reduce noise. Compared to traditional options like cellulose or fiberglass batt insulation, spray foam delivers superior energy efficiency, durability, and long-term cost savings.​
