Functions of Foam Sealant

Sure-Seal™ saturated foam sealant tape is an advanced, moldable gasket tape for contractors that combines the impenetrable performance of typical sealants with the convenience and flexibility of a tape. This innovative foam sealant replaces caulk, spray foam, putty tape, butyl and other liquid sealants, which can be messy and difficult to apply. Use our foam sealant tape in construction projects to stop air and water from penetrating residential and commercial structures. Saturated foam sealant tape resists UV and ozone degradation while remaining flexible. In other words,  it won’t dry out or crack.

Foam Sealant Tape for Construction and Housing

Contractors use Sure-Seal™ foam sealant tape to fill irregular spaces and block air, vapor, moisture, dust, and even noise. Foam tape expands and contracts to compensate for uneven gaps and spaces. Replace traditional foam sealants with our revolutionary tape that lasts for over 20 years in various areas of building construction. Simply peel the adhesive backed foam off of the paper backing and press into place for use in these construction applications and more:


  • Residential structures
  • Drywall gasketing
  • Commercial buildings
  • Airtight drywall
  • Structural retrofitting
  • Weather sealing
  • Asbestos and concrete junctures
  • Windows and doors meeting brickwork
  • Manufactured housing
  • Concrete expansion joints
  • Curtain walls
  • Prefabricated elements
  • Energy efficient building
  • Joist isolation
  • Wood and concrete construction


Sure-Seal™ foam sealant tapes come in a wide range of sizes from 1/4” to 1-1/4” thick and 3/16” to 39” wide. Our made to order foam tapes are wound on 3” core tubes with a paper liner on one side to protect the adhesive backing.


LAMATEK™ also supplies custom made foam sealant gaskets with our state of the art die cutting equipment. Let us engineer custom Sure-Seal™ parts and gaskets to fit your specific building application. Saturated foam sealing gaskets are supplied kiss cut on a roll so you can easily peel them off and stick them in place. We can leave the matrix intact or remove it for fast, convenient, applications.


Sure-Seal™ foam tape is made from a resilient, open cell urethane foam that is impregnated with a proprietary saturant to provide superior sealing qualities. This innovative material seals like closed cell foam but won’t take a compression set. Foam sealant tape conforms to irregular surfaces to fill uneven gaps and spaces while the single sided adhesive bonds with a strong hold. In addition, foam sealant tape requires no drying time! Say goodbye to tedious, messy sealants and switch to Sure-Seal™ foam tape for all of your construction projects.

Tip from the Experts

Sure-Seal™ foam must be compressed at least 50% to get the best air and water-tight sealing. It’s easy for you to choose correct thickness. Just measure the largest gap area and double it!
