Overview

Rw rates the tested doorset, not the leaf alone — and the weakest gap sets the result.

Reaching about 45 dB Rw (ISO 10140) means building and sealing the complete doorset: a dense, multi-layer acoustic core for mass; a continuous airtight line of compression seals on head and jambs; an automatic drop seal closing the threshold when shut; acoustic-rated, sealed hardware with no open undercut; and a frame designed and installed to the same rating. Guestroom doors commonly target 35–45 dB Rw depending on brand standard and adjacency. The same doorset can be combined with a fire rating.

What Rw actually means

Rw is a single-number rating of how much airborne sound a doorset reduces, in decibels — higher is quieter. It describes the tested doorset (leaf + frame + seals), not the leaf alone, and is governed by the weakest path: one unsealed gap can undo a heavy leaf.

Automatic drop sealCloses the floor gap when shut

Sealed hardwareAcoustic-rated, no open undercut

Sealed frame, no flanking path

The leaf is only half the result — a frame matched to the leaf rating and sealed to the wall removes the flanking path. KENT designs and seals the frame to the same number, and a ventilation undercut is replaced by a ducted, attenuated air path.

FAQ

Questions specifiers ask

What Rw do hotel guestrooms need?+

Commonly around 35–45 dB Rw depending on the brand standard and adjacency; corridors and party conditions drive the number.

Does a ventilation undercut ruin acoustics?+

Yes — it is an open air path for sound. Provide make-up air through a ducted, attenuated route and close the threshold with a drop seal.

Is mass enough?+

No — mass helps, but seals and the complete doorset govern the result. The weakest gap sets the rating.

Can it be fire-rated too?+

Yes — both ratings can be combined in one certified doorset, up to 45 dB Rw.

Acoustic performance is a property of the installed, sealed doorset; site sealing and the surrounding construction affect the result. Images are indicative until project photography is supplied.
