Is Sound A Problem?

Highest Field Operable STC Ratings

"Cush 'N' Seal"© Frame Seals
  • #105 Four fins have the highest field STC Ratings in the industry for standard 20 or 90 minute Guest Entry or Connecting Room Doors
  • #105-3HJ Three-fin seal option. The only seal that does not create bind on full-mortise continuous hinges. Used on hinge jamb only
  • Warranted to block light and sound!
  • Only DHSI knows STC Ratings are only as practical as the seals and flooring/transition details. Ask for DHSI comparative STC testing of higher rated openings

Meets ADA transition, NFPA 101 Self Closing and the new NFPA 80 2007 Fire Code Requirements

Why DHSI Works:
  • Warp and Out-of-Plumb don't affect DHSI Frame Seals. Self compensating for warp, thermal bow, and out of plumb
  • Others can not compensate! GAP = Light, sound and smoke!
  • Adhesive warranted for life of the installation at interior
