INFILL AND OVERSAIL SYSTEMS
Infilling systems for walls
Light steel exterior walling systems are widely used in multi-storey framed construction to provide a prompt and dry building envelope across various building types. These systems are considered to be a cost-effective and efficient approach for constructing facade walls. There are two prevalent categories of walling systems, namely infill walls and oversail walls, which are alternatively referred to as continuous walling.
The phrase “Infill Walling” refers to the placement of exterior walls between the floors of a building’s core structural frame. These walls serve the purpose of providing support for the cladding system. Light steel infill walls, which are much lighter and thinner compared to traditional block construction, do not impose substantial line loads on floors.
The primary function of infill walls is to counteract wind loads exerted on the facade, rather than providing support for floor loads. The use of vertical C section studs for light steel infill walls is widespread in both steel and concrete-framed structures, and has mostly supplanted masonry or wood alternatives.
The size and spacing of the C section are determined by the specific structural needs. Additionally, the spacing is chosen to ensure compatibility with the materials used in the exterior façade. The layouts are designed to provide support for windows and openings, and extra studs are added around openings to secure brick tie channels and facades. The panels included inside the major structural frame are comprised of a lower track affixed to the floor and an upper track affixed to the underside of the level above, facilitating the deflection of the structure. Wall panels may be manufactured in advance as large units at a distance from the construction site or constructed on-site using C sections that are provided in a pre-cut length. The absence of cutting on-site results in a reduction in noise and danger.
Light steel infill walling systems have the capability to be used in conjunction with many forms of cladding, including both substantial cladding options like brickwork, as well as more lightweight alternatives such as insulated renders and rain-screens.
Advantages
The constructional benefits of light weight, rapidity, and simplicity of installation have significant importance.
Swift implementation enables much earlier entry for subsequent transactions.
The installation procedure is devoid of moisture, hence eliminating any issues related to shrinking and drying-out.
Architectural elements such as expansive windows, parapets, and other features may be included.
Certain boarding systems may attain a fire resistance of 120 minutes.
The integration of facade features may lead to the attainment of exceptional acoustic performance.
According to system data, unique insulation may reach high levels of thermal performance.
There are already available comprehensive infill panel systems that have undergone testing in both interior and exterior spaces. These systems provide system warranties and a ‘golden thread’ guarantee, therefore mitigating risks for clients, developers, primary contractors, and insurers.
Overland retaining wall systems
Light steel external oversail walls are a cost-effective and effective approach for constructing exterior walling systems in steel and concrete framed structures. These walls are specifically engineered to withstand wind loads on the facades and to bear their own weight as well as the weight of any lightweight cladding materials connected to them.
Continuous walling is often built from the outside of the building, extending over the edge of the main structure. Studs are secured using cleats to maximise the available floor space. Oversail components are analogous to those used in infill walling. Nevertheless, there are notable disparities that need careful consideration in the realms of design and construction.
In contrast to infill walls, oversail walls are positioned externally to the core structural frame, as opposed to being positioned between the floors. Oversail walling systems are well-suited for scenarios in which the cladding materials exhibit sensitivity to variations in the positioning of the primary frame. In order to accept vertical loading from the cladding, it is essential to ensure the provision of sufficient foundation support. It is possible to incorporate openings in the building facade and a range of cladding alternatives. The continuous exterior walling system comprises vertical components made of light steel C sections, which are securely attached to the main frame using bracket connections. The inclusion of slotted connections is often necessary to accommodate the movement of the main frame inside the connections.
The basic structure or foundations must directly sustain the dead weight of masonry cladding. Nevertheless, light steel exterior walling systems often provide horizontal wind resistance by using a unique system of brick tie channels and brick ties securely attached to the stud.
The design of both infill and oversail exterior walling systems must take into account several factors, including structural requirements, fire resistance, condensation risk, weathertightness, thermal insulation, acoustic performance, and the need to accommodate interfaces at windows, patio doors, and balconies.
