Into every architect's life a client comes who wants their project to include operable walls with "as high acoustic value as possible". If we spec an operable wall above Rw50 for a greater level of separation, there are a number of factors that need to be considered.
The most notable consequence of chasing "as high acoustic value as possible" is day-to-day operation of the wall. To achieve the highest-level ratings, the panels become inherently heavier and are difficult to operate on a semi-regular basis.
A second consequence is that every panel is only ever as good as its acoustic partner: the seals. Most builds above an Rw53 need to double up on seals. Where a standard operable wall system incorporates retractable bottom seals for ease of operation, some higher-rated walls require a combination of retractable seals plus fixed sweep seals. Coupling fixed sweep seals with heavier panel weight can result in these highly rated systems incurring drag along the floor.
Here's a practical framework for getting the balance right without over-specifying:
First, carefully read your acoustic report and discuss it with the client around expectations. The desire for an extremely high level of separation should never override safe and simple operation for all users. An acoustic rating of Rw50 or greater may also be unnecessary for how the space will actually be used and the sound management it requires.
Second, weigh the variables of operation, acoustics, and budget. Operable walls with very high ratings typically incur very high costs and 5 points or more can be due to a good or poor installation along with integrity of the surrounding based build and flanking.
Finally, avoid incorporating passdoors into operable walls unless absolutely required (they will always be a weak point for sound leakage) consider other paths of egress into the space.
An operable wall should always close to the rear of any stack recess rather than to the face of any joinery cupboard doors.
Consider Side or Remote stacking rather than Centre stacking for all walls over Rw49. Individual panels are far more user friendly than Centre stacking hinged pairs with less risk of finger entrapment. This also delivers the bonus of not having the full wall weight as a live point load, reducing the extent of overhead structural support required.
Make sure your specification delivers performance that genuinely serves your client's needs, not just the highest number on paper. Talk to a GLYDE expert about your next project.
