SUNRISE, Fla., Oct. 6, 2026 /PRNewswire/ -- Flex Foam™ is the newest innovation to join the ever-growing Flex Seal Family of Products. The super-thick foam sealant instantly expands to fill gaps, cracks, and holes to block out moisture, drafts, pests, and more.

"Ordinary foams are stiff and break apart, but Flex Foam is different," said Phil Swift, CEO, Inventor and Spokesman for the Flex Seal Family of Products. "It stays flexible and moves with surfaces, so it holds on strong, even when walls and foundations shift."

Flex Foam™ is a highly flexible, white expanding polyurethane foam designed to fill gaps and holes, insulate, and create a water-resistant seal that helps block moisture, drafts, pests, and noise. Its low-pressure, high-density formula provides strong adhesion without bowing or warping window and door frames.
