Coordinate the complete opening around a measurable sound-control target instead of treating the door leaf as an isolated acoustic product.
STC or Rw performance depends on the tested door, frame, perimeter seals, threshold, glazing, hardware preparation and installation. A high-rated leaf cannot compensate for uncontrolled gaps or an incompatible frame.
WONLY helps project teams define the target, review the evidence boundary and coordinate security, fire, access-control and acoustic requirements before drawings and samples are approved.
State the required STC, Rw or project-specific criterion and the test method used by the consultant.
Confirm wall type, frame profile, clearances, threshold and interfaces that affect leakage.
Coordinate perimeter seals, drop seals, meeting stiles and floor conditions for the tested configuration.
Review viewers, locks, closers, access control and cable routes because every penetration can affect performance.
Resolve fire, egress, accessibility and security requirements without invalidating the acoustic assembly.
Define installation tolerances, inspection steps and any field test or commissioning requirement.
Issue the acoustic target, wall build-up, opening schedule, hardware and other performance requirements.
Select a documented assembly and identify differences between the tested specimen and proposed opening.
Approve drawings, seal details, samples and installation interfaces before production.
Inspect delivery and installation, record gaps and complete the agreed site acceptance checks.
Compare the report specimen, size, frame, seals, threshold, hardware and opening direction with the proposed doorset.
Show continuous sealing at head, jambs, sill and meeting stiles, including hardware interruptions.
Record anchors, clearances, compression and automatic drop-seal contact before handover.
Agree visual inspection, gap measurements and any acoustic field testing before procurement release.
No. They are different rating systems and should not be treated as numerically interchangeable without an acoustic consultant's review.
Yes when its preparation, cable route and hardware remain compatible with the documented assembly and seal strategy.
No. Field performance also depends on wall interfaces, installation quality, gaps, seals and adjacent construction.
