Controlling structure-borne noise starts at the connection point. When ceilings and services are fixed directly to the primary structure, vibration has a direct path between spaces, carrying impact and service noise through the building assembly.
The Resilmount® A50R Isolation Ceiling Hanger suspends a ceiling, service, or secondary structural element from the primary structure through a resilient element rather than a rigid connection. At the core of every A50R is a patented thermoplastic rubber compound engineered to outperform standard rubber in acoustic isolation. The compound absorbs and dissipates vibrational energy before it transfers into the supporting structure, helping break the path that would otherwise carry impact and vibration noise between spaces.
Tested and Rated for Performance
The Resilmount A50R Isolation Hanger is developed within Studco’s extensive, ongoing product research and testing. This gives specifiers performance data they can rely on prior to specification.
The A50R is tested and evaluated for STC and IIC performance through rigorous laboratory testing at independent facilities, including Riverbank Acoustical Laboratories. Testing is conducted in strict accordance with ASTM standards and independent quality management guidelines. Sound transmission is measured using two ratings. The STC and IIC ratings give specifiers a standardised basis for comparing acoustic performance across products.

Proven on Completed Projects
The A50R range has been specified on completed developments where acoustic performance is central to the offering. At Watermark Pointe Beachfront Collection, a resort-style waterfront condominium community in New Rochelle, NY, the Resilmount team worked closely with builder Regional Construction to supply an effective acoustic isolation solution for the apartment buildings.
The buildings were fitted with Resilmount A50R-3 Isolation Hangers to isolate the ceiling system from the floor structure above, reducing structure-borne and airborne noise between neighbouring apartments and nearby city sound.
Part of a Wider Resilmount Acoustic Isolation System
The A50R Isolation Hanger is one component of Studco’s broader Resilmount system, which also includes the A237R Furring Channel Sound Isolation Clip, A130R Heavy Duty Sound Isolation Mounting Bracket, the MBFR BetaFix Furring Channel Sound Isolation Clip, and the W20R Sound Isolation Washer. Specifying isolation hangers alongside complementary products helps ensure a ceiling assembly is isolated consistently at every connection point. Where a project requires it, the Resilmount team will work with specifiers to develop a custom assembly suited to the project.
Summary
The A50R Isolation Hanger is a small but critical part of Studco’s sound isolation system, and its performance is proven, tested and rated to recognized acoustic and structural standards. Specifiers ready to include the A50R in an upcoming project can contact the Resilmount team for technical data sheets, submittal support, or a custom assembly recommendation.

- The A50R range has been proven on completed developments, including large-scale residential projects such as Watermark Pointe in New Rochelle, NY.
FAQ
A sound isolation hanger suspends ceilings, services, or secondary structural elements from a building’s primary structure using a resilient element. This breaks the rigid connection that would otherwise carry structure-borne noise and vibration between spaces.
A standard rigid hanger creates a direct path for vibration to travel into the structure. The Resilmount A50R Isolation Hanger introduces a patented, thermoplastic rubber element engineered to outperform standard rubber in acoustic isolation, while reliably carrying the sustained load of the suspended element.
Isolation hangers must maintain both structural load capacity and acoustic performance. Resilmount A50R Isolation Hangers are laboratory tested and rated for load capacity and acoustic performance, including STC and IIC, at independent, accredited facilities.
No. The need is more visible in tall, dense developments with shared structure and mechanical plant, but isolation hangers are relevant wherever structure-borne noise between spaces is a concern, including lower-rise multi-family and mixed-use buildings.
Selection depends on the load requirement of the element being suspended. The Resilmount A50R isolation hanger range is colour coded by rubber element: red, black, and blue, with each colour rated for a different weight capacity. Specifiers should calculate the total weight of the ceiling or service, add a margin to avoid overloading the isolation element, and match it to the corresponding hanger below. The Resilmount team is available to confirm suitability for specific applications.
