Precast concrete cladding is a form of cladding that uses off-site manufactured precast concrete panels. It is also known as architectural precast cladding or reconstructed stone. They are increasingly specified to clad a wide range of buildings, including commercial and civic offices, residential, retail, leisure, hospitals, schools, and so on.

Precast concrete is a form of concrete that is prepared, cast and cured off-site, usually in a controlled factory environment, using reusable moulds. Precast concrete elements can be joined to other elements to form a complete structure.

The production of precast concrete elements takes place under controlled conditions in enclosed factories. This means that tolerances can be accurately controlled, waste can be minimised, and that a denser, stronger and better quality concrete can be produced.

Due to innovative production methods, precast concrete panels can be manufactured in a wide range of finishes and facing, shapes and sizes, according to the specific requirements of the building. The colour and finish of stone, masonry or terracotta can be carefully replicated, with the incorporation of architectural details such as cornices, quoins, arches and decorative relief panels.

The energy efficiency of the panels is considerable. Sculptured shapes such as recessed window walls and vertical fins enable the design of many types of shading devices for window areas, thereby helping to reduce glare and solar gain. In addition, insulation can be fixed to the back of the panels, or incorporated into a sandwich wall panel.

Panels can be supported by the structural frame of the building or can be self-supporting and restrained. They can also be designed, if necessary, to support floors by bearing load. Panels tend to be 150 mm thick, and are designed to span either between columns or between floors, which allows large areas to be enclosed.

Panels are manufactured by casting in purpose-built timber or fibre glass moulds. Steel reinforcement cages are placed in the mould prior to pouring the concrete. Increasingly, prefabrication can incorporate the fixing of other elements such as insulation and windows. When the moulds are removed, the exposed surfaces can be treated in various ways, such as acid-etching, smooth or coarse grounding, grit or sand-blasting, rubbing or polishing, according to the quality of surface finish specified.

Having been transported to site, tower or mobile cranes lift the panels into position, with fixings restraining them back to the structure. This means that external scaffolding is often not required.

Since precast panels result in a thinner external wall than conventional double-skin walls, the lettable floor area is increased.
