Two key differences between latex foam and GREAT STUFF PRO polyurethane foam sealant:
  1. Latex foams are typically "open celled" and, as a result, can take on water. In fact, the same properties that allow you to wash latex foam off your hands with water also mean that the cured foam can absorb water. This can cause wood rot or deterioration in areas where wet latex foam is next to wood, such as a window frame. In contrast, GREAT STUFF PRO is closed-cell foam. It forms a water-resistant outer skin when cured.


  2. Latex foam does not expand. GREAT STUFF PRO expands to thoroughly fill all voids and cavities making it an ideal air-sealant.
