Closed-Cell Spray Foam Insulation

Closed-cell spray foam insulation is a premium, high-density insulation material known for its exceptional strength, moisture resistance, and thermal performance. Unlike open-cell foam, closed-cell insulation features a tightly packed structure of sealed air pockets, which gives it a rigid finish and a superior R-value—typically around R-6 to R-7 per inch.

When applied, the foam expands and hardens into a solid layer that not only seals air leaks but also acts as a vapor barrier, preventing moisture intrusion. This makes it especially valuable in areas prone to humidity, flooding, or temperature extremes—like crawl spaces, attics, exterior walls, basements, and metal buildings.

Additionally, closed-cell spray foam adds structural strength to walls and roofs, helping to reinforce buildings against wind uplift and storm damage—an important consideration for homeowners in Florida’s coastal and hurricane-prone areas.

This type of insulation is widely used in both residential and commercial construction for its durability, energy savings, and ability to protect against mold, mildew, pests, and long-term water damage.
