Reinforced Concrete Sandwich Panels (RCSP) are getting popularity in construction industry day-by-day, due to their various advantages over conventional systems, such as light weight, speedy construction, and thermal, moisture, and sound insulation, etc. Use of RCSP in building and construction industry was started in North America more than 50 years from now.
EPS Panels with wire mesh 50 x 50 for load bearing for G+2 EPS Panels with wire mesh combined with beams for higher floors
- Hikae Equs single wall panels are an ideal choice for the traditional bricks, blocks and any other types of construction materials.
- It provides very good thermal comfort and makes the building energy efficient.
- No beam or column is required upto G+2.

Let’s understand what is termed as a single panel wall:
A central layer of low strength material, is known as ‘core’ which is protected by outer layers of high strength material, known as ‘wythes’ or ‘skin layers’. Expanded Polystyrene (EPS) with flat or undulated surface profile, is commonly used as core in a single piece. While the wythes are usually made of micro-concrete or cement and coarse-sand mortar.
The key components of a reinforced concrete sandwich panel are as follows:
Outer Concrete Layers (Wythes)
These are the two layers of concrete that form the exterior surfaces of the panel. They provide protection from the elements, contribute to the structural integrity of the panel, and can be designed with various architectural finishes and textures. Concrete is a strong and durable building material known for its compressive strength. In the case of Sandwich Panels, it is often used in a precast form to ensure quality and consistency.
Reinforcement
To enhance the structural strength of the panel, steel reinforcement, such as rebar, is incorporated within the concrete layers. This reinforcement helps the panel withstand loads and stresses, such as wind and seismic forces. The reinforcement in wythes is provided in the form of welded TMT- bars in longitudinal and transverse directions. The outer layers (wythes) are inter-connected either by shear connectors (orthogonal or inclined wires. The function of shear connectors is to hold the wythes and core in place, as well as to transfer the longitudinal shear between the wythes.
Insulation Material
The insulation material is placed between the two concrete wythes. It serves as a thermal barrier, helping to regulate the temperature inside the building. We use expanded polystyrene (EPS) in these panels.
