Sandwich panels are composite materials that consist of two outer layers and a core material in between. The outer layers are typically made of metal, plastic, or fiberglass, while the core material can be made of foam, honeycomb, or other materials. These panels are used in a variety of applications, including building construction, transportation, and industrial applications.
In the market, sandwich panels are available in standard sizes and thicknesses. The standard sizes range from 1 meter to 12 meters in length and 1 meter to 1.2 meters in width. The thicknesses available range from 30mm to 200mm.
The most common types of sandwich panels available in the Indian market are:
1. Polyurethane (PU) sandwich panels:
These panels have a polyurethane foam core and are used in cold storage, clean rooms, and other applications where insulation is required.
2. Polystyrene (EPS) sandwich panels:
These panels have an expanded polystyrene foam core and are used in roofing, walls, and ceilings.
3. Rockwool sandwich panels:
These panels have a mineral wool core and are used in fire-resistant applications.
4. PIR sandwich panels:
These panels have a polyisocyanurate foam core and are used in high-temperature applications.
In conclusion, sandwich panels are versatile composite materials that offer excellent insulation properties and are widely used in various industries. The standard sizes and thicknesses available in the Indian market make it easy for builders and manufacturers to incorporate them into their projects.
