Intertenancy walls are inherently complex due to their multifaceted roles in designs for projects such as multi-residential buildings and hotels, where robust and effective solutions for comfort, privacy and safety of occupants are essential, whilst maintaining design requirements and flexibility.

Rondo has developed their products and services to address key aspects of successful intertenancy wall design and construction, considering acoustic performance, design flexibility, fire safety, and construction efficiency as a complete and compliant solution to achieve structural integrity.

Acoustic isolation, design flexibility and efficiency

Effective sound isolation (in accordance with clause G6 of the building code) is crucial to ensure privacy and minimise disturbances between neighbouring units. The unique shape of the GIB Rondo Quiet Stud used for intertenancy wall framing, is designed to reduce sound transmission through walls without the drawback of installing a traditional staggered stud design.

Eliminating a staggered stud design by installing Quiet Stud can also have a positive advantage for design flexibility, including:

• Decreased footprint of walls, maximising valuable floor space
• Increased wall heights and maximised stud centres — Quiet Stud has the option of a thicker BMT which accommodates an increase in wall height

Fire safety and insulation

One of the main roles of an intertenancy wall design is to prevent the spread of fire between neighbouring units. Intertenancy walls must adhere to an FRL of no less than -/60/60, relating to the performance of insulation, structural and integrity.

Leading plasterboard manufacturer GIB use Rondo steel wall framing to conduct and achieve compliant fire testing for intertenancy wall systems. Rondo steel framing provides superior support for insulation in walls in the event of a fire, helping to better protect the non-fire side of the wall, and maintaining structural integrity for a longer period, which is crucial for occupant safety.

Structural integrity

Overall structural longevity of intertenancy walls is essential. A well designed, compliant wall will ensure that the wall is far less likely to experience cracks, or damage which would compromise acoustic and fire performance over time. Rondo wall designs and steel framing for intertenancy walls provide compliant and quality support for plasterboard and insulation, including superior corrosion protection.

To assist you in obtaining the very best results for your project, Rondo has a team of qualified, highly experienced design engineers, who specialise in the compliant and efficient design of lightweight steel wall and ceiling systems.
