Cantilevers

Designing cantilevered terraced houses is simplified with KOROK® fire and acoustic wall systems. Whether you need cantilevered eaves or cantilevered walls, KOROK has detailed solutions to suit your needs.

Our systems help you create functional and stylish designs, such as:

• Weather protection with inset front doors for enhanced shelter.
• Maximizing floor space with larger second-story extensions.

KOROK’s innovative cantilevered wall systems are engineered to provide superior performance, offering both structural stability and efficient installation for terraced house construction. Choose KOROK® to streamline your building process and meet the demands of modern architectural design.

For Terraced Housing

Cantilevered terraced house design is easy with KOROK®. We have details for both cantilevered eaves and cantilevered walls. So if you’re wanting your buyers to be sheltered from the weather with an inset front door; or if you’re wanting to maximise your floor space with a larger second storey, we have the product to make that happen.

Cantilevered Walls

For External Applications

A Typical Parapet Detail illustrates the structure and support of a parapet wall, commonly cantilevered from the main building structure. This detail focuses on connections that ensure stability and durability, including reinforcement and weatherproofing layers to protect against the elements. Cantilevered parapets require careful attention to load distribution and deflection control, as they extend outward without external bracing, creating a clean, streamlined edge on the building façade.

KOROK® 78mm Galv Panel

High Performing and Lightweight

KOROK® 78mm galv panels are rollformed from zinc coated steel strips. The steel from which the shells are manufactured conforms to AS/NZS1397:2001.

Steel shells have a base metal thickness of 0.4mm B.M.T. with a Z275 zinc coating. These panels have an aerated concrete core and weigh nominally 10.2kg per lineal metre.

KOROK® 51mm Galv Panel

High Performing and Lightweight

51mm KOROK® panels are rollformed from zinc coated steel strips. The steel from which the shells are manufactured conforms to AS/NZS1397:2001. Steel shells have a base metal thickness of 0.4mm B.M.T. with a Z275 zinc coating. These panels have an aerated concrete core and weigh nominally 10.2kg per lineal metre.

KOROK® produces 51mm panel. KOROK® 51mm panel provides a -/60/60 FRR and is perfectly suited for terraced house intertenancy walls and apartment intertenancy walls.  The narrower gauge allows you to keep more floor space as it isn’t taken up by walls.

Performance and Features

• Fire Rating: KOROK® 51mm panels provide a fire resistance rating of -/60/60 FRR, meeting stringent safety requirements for intertenancy walls in terraced houses and apartments.
• Acoustic Efficiency: Designed to reduce sound transmission, these panels ensure quieter living environments, making them an excellent choice for densely populated or high-traffic areas.
• Space-Saving Design: The 51mm thickness allows for slimmer walls, helping to maximize valuable floor space without compromising structural integrity or performance.

KOROK® 51mm galv panels are used for:

• KOROK® Intertenancy Terraced Housing Wall Systems
• KOROK® Intertenancy Apartment Wall Systems

Applications and Systems

• Vertical Orientation: Panels are installed vertically and secured to timber or steel framing with aluminum brackets.
• Versatility: Compatible with wall framing, insulation, and linings specified within the system appraisal, ensuring seamless integration into your building project.
• Scope of Use: Appraised for all buildings of all importance levels as defined by AS/NZS 1170.

Intertenancy Terraced Housing Systems – Fire and Acoustic Rated Protection

In modern terraced housing and townhouses, traditional framed wall systems depend on internal linings to provide fire resistance. Any penetration through these linings can compromise the fire-rated barrier, increasing the risk of fire spread. The KOROK® Intertenancy System offers a superior solution, where the primary fire barrier is located between the structural frames, protecting the building on the side opposite to the fire.

How KOROK® Intertenancy Systems Work

The KOROK® Intertenancy System utilizes aluminium brackets to attach the KOROK® fire-rated panels to both frames. In the event of a fire, the brackets on the fire-exposed side melt, allowing the structure on the fire side to detach safely. This innovative design ensures that the KOROK® panels remain securely supported by the brackets connected to the non-fire side, providing continued fire protection and maintaining the integrity of the structure.

Acoustic and Fire-Rated Solutions for Terraced Housing

In addition to superior fire resistance, the KOROK® Intertenancy System offers excellent acoustic insulation, making it an ideal solution for townhouses and multi-residential developments. By minimizing noise transfer between units, the KOROK® system enhances privacy and comfort for occupants.

KOROK® Cantilever Design

The KOROK® Cantilever feature in the Intertenancy Terraced Housing Systems ensures that the panels remain stable during a fire, further enhancing the safety and reliability of the system. This design meets strict building code requirements and is fully tested to withstand fire scenarios. KOROK® Cantilevers
