How our certified crews deliver precision attic insulation in Cornelius, NC.
Every project begins with a thorough inspection of your property. We evaluate the existing condition, identify problem areas, and use infrared moisture scanning when needed to reveal hidden issues. You receive a detailed report with photos and honest recommendations.
We prepare every surface according to factory guidelines — cleaning contaminants, addressing moisture, repairing damaged substrate, and verifying adhesion conditions. This step is not glamorous, but it is the foundation of a spray foam system that lasts decades.
Application is performed by certified spray foam technicians using the latest proportioning equipment. We monitor foam temperature, pressure, and ratio throughout application to ensure every square foot meets manufacturer performance specifications.
After the foam cures, we apply a UV-protective coating — silicone, acrylic, or elastomeric — selected for your specific application and climate. We then remove all masking, clean up the work area, and conduct a final walkthrough with you to verify satisfaction.

Real feedback from property owners who trusted Lapolla Industries with their spray foam projects.
"We chose silicone over acrylic for our flat roof recoat and it was the right decision. Handles ponding water without softening and the UV resistance is excellent. Lapolla Industries recommended the right product for our situation."
"Had a few spots where birds had pecked through the coating on our foam roof. The repair crew patched every spot and applied a fresh topcoat over the entire section. Looks brand new and no more leaks."
"Had our attic insulated with spray foam after years of fiberglass that kept settling and losing its R-value. Lapolla Industries did a clean install — no gaps, no missed spots. Our HVAC system runs half as much now."
