Precast concrete wall panels come with a number of distinct advantages. Economy, ease of handling, low material and labour cost, strength and verticality are among the reasons they are growing in popularity. Precast wall panels are now used in areas of the building. There are four types of precast wall panels that are usually used in construction. Let’s learn more about these –

Cladding or curtain wall panels – Cladding walls are the walls used to build the exteriors and the interiors of your construction project. The use of precast panels in the construction of walls has grown increasingly common. Cladding walls can be constructed to include a variety of colours, finishes, and textures. Also known as curtain walls, these walls offer superior aesthetics. Apart from the interiors of the residential or the commercial property, precast boundary walls and facades are now being built as well. The addition of materials such as bricks and terracotta has become common in compound walls. Stone or silica based materials are similarly used in precasting interior cladding walls.

Loadbearing wall panels – Loadbearing walls act as loadbearing elements that transfer the roof and floor (vertical and horizontal) loads into the foundation. They are important for the structural integrity of the building. Precast concrete panels are known for their strength and for their thermal and fire-resistant properties making precast panels an excellent choice for constructing loadbearing walls. The ability of precast concrete panels to support other structural members such as beams and walls on the floors above, makes them ideally suited for load bearing walls. The dimensions of precast walls can also be customised making them ideal loadbearing elements.

Shear walls – Shear walls are structural walls that resist and provide protection against lateral forces. These could include wind forces or even seismic forces in case of an earthquake. These shear walls are very important when it comes to high-rise projects which are particularly vulnerable to earthquake activity or high wind speeds. Precast concrete shear walls can be either placed around the perimeter of the building or can form the core (around the lift shaft or the stairs. The high resistance and strength of precast walls make them perfect for use as shear walls.

Framework walls – Sometimes builders design their project in such a way that the precast concrete wall panels are used as a framework. The remainder of the wall is either composed of traditional walls or as cast-on-site concrete units. The precast concrete panels now provide a stable framework for the structural component adding to both the strength and enhancing the aesthetics of the wall itself. Most readymade walls also follow this design of a precast framework that can be put in place with the remaining concrete wall cast or constructed at the site itself.

Sandwich walls – Sandwich walls are usually used for areas which need high thermal insulation. Facades, exteriors, and sometimes even roofs are constructed with panels between reinforced concrete shells. Between the shells and the inner core are sheathes of insulation material. These help in greater fire and heat resistance. The enhanced insulation properties makes sandwich walls suitable for a number of different construction projects.

The construction of larger projects and high-rise complexes have now made it necessary to include precast concrete walls in almost all areas – from standalone perimeter walls to facades, from exteriors to highlight walls in the interior. Precast concrete walls can both enhance aesthetics and be economical in such large scale projects.
