Acoustic Door Systems
Acoustic and STC-Rated Entrance Doors
Coordinate the complete opening around a measurable sound-control target instead of treating the door leaf as an isolated acoustic product.
Acoustic Performance Belongs to the Complete Opening
STC or Rw performance depends on the tested door, frame, perimeter seals, threshold, glazing, hardware preparation and installation.
What Buyers Should Define Before Quotation
State the rating system and target, wall and frame construction, seal strategy, hardware preparation, conflicting fire or egress requirements and site acceptance method.
Evidence Before Award
Compare the proposed opening with the test specimen, approve seal-detail drawings and define installation and field-verification checkpoints.
Procurement Questions
Is STC the same as Rw?
No. They are different rating systems and should not be treated as numerically interchangeable without an acoustic consultant review.
Does a laboratory rating guarantee site performance?
No. Field performance also depends on wall interfaces, installation quality, gaps, seals and adjacent construction.
