GE General Purpose Insulating Foam


Gaps and cracks are a source of energy loss as heated or cooled air from inside the home leaks outside. General Purpose Insulating Foam forms an airtight bond, sealing out air and reducing energy loss. The foam expands to fill, seal, and insulate cracks and spaces where conventional insulation is difficult to install and the gaps are too large for caulk to fill.


Latex foam is typically open-cell, meaning it can absorb water, leaving the area vulnerable to water damage. Water absorption can cause rot and mold issues in places where the soaked foam is next to wood. General Purpose Insulating Foam's closed-cell technology repels water, helping prevent rot and mold.


  • No shrinkage
  • Sandable and paintable
  • High R-5 insulation value

Don't Waste Time and Energy

Not all caulk is the same. Because silicone is permanently waterproof, flexible, and shrink-/crack-proof, unlike most non-silicone caulks, it won't leave gaps or cracks for air and water to seep through over time. Those leaks can lead to water damage, mold growth, and higher energy bills—all of which can translate into your lost time (when you have to do the job again), lost energy, and lost money.
