Flex Seal Expands Lineup with Flexible Polyurethane Foam

The new product aims to solve a common frustration in home repair: expanding foams that bow or warp delicate door and window frames. By utilizing a low-pressure, high-density formula, the foam provides structural adhesion while blocking moisture, pests, and noise. Once cured, the white sealant can be trimmed, sanded, or painted to match existing surfaces.

Designed for both indoor and outdoor utility, the material adheres to a variety of substrates including brick, metal, wood, and PVC. The company is positioning the product as an energy-efficiency tool, emphasizing its ability to seal drafts effectively. Flex Foam is currently available through the company’s website and Amazon, with a wider rollout to physical retail locations planned for the coming months.
