Trusted attic insulation in McHenry, IL. Our certified crews deliver precision workmanship and guaranteed results.
Attic insulation with spray foam in McHenry, IL delivers immediate comfort improvement and measurable energy savings. Our closed-cell foam creates a continuous air barrier from ridge to eave that fiberglass and cellulose simply cannot match — no gaps, no settling, no thermal bypass.
The buildings and homes of McHenry, IL face unique challenges — from seasonal temperature extremes to storm exposure — that demand roofing and insulation systems built for performance, not just price. Lapolla Industries delivers attic insulation solutions using closed-cell spray polyurethane foam that outperforms conventional materials in every measurable category.
Our McHenry customers see the difference in their energy bills, their comfort levels, and the longevity of their roofing systems. Spray foam does not degrade like fiberglass, does not develop seam failures like TPO, and does not crack like built-up roofing. It is a permanent solution — and Lapolla Industries is the permanent partner McHenry property owners rely on to deliver it right.
From inspection to completion, here is how we deliver professional attic insulation results.
Before any work begins, our certified inspectors evaluate your property and provide a comprehensive assessment including current condition, repair needs, and recommended SPF solutions. You get a written estimate with no hidden fees.
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.
Our factory-trained crews apply spray polyurethane foam using calibrated equipment that ensures consistent thickness, proper density, and complete coverage. The foam expands on contact, fills every gap, and bonds permanently to the prepared substrate.
We finish every project with the appropriate protective coating, thorough cleanup, and a detailed walkthrough. You receive project documentation including photos, material specifications, warranty registration, and maintenance recommendations.

Real feedback from property owners who trusted Lapolla Industries with their spray foam projects.
"Water was coming in around our skylight every time it rained. Lapolla Industries traced it to deteriorated sealant and improper flashing. They redid everything and we have been bone dry through two heavy storm seasons now."
"Got a comprehensive inspection done on our warehouse roof. They found three areas of trapped moisture that were invisible from the surface. The early detection saved us from much more expensive structural repairs down the road."
"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."
