What Is a Sandwich Panel?

A sandwich panel is a factory-manufactured building component consisting of two outer facings with an insulation core between them.

The outer facings are generally made from coated metal sheets, while the core material provides thermal insulation and other performance characteristics depending on the panel type.

Sandwich panels are commonly used in:

• Industrial roofing
• Factory wall cladding
• Warehouses
• Cold storage facilities
• Food processing units
• Pharmaceutical facilities
• Clean rooms
• Pre-engineered buildings

Their integrated construction makes them suitable for building envelopes that require insulation and efficient installation.

Main Components of a Sandwich Panel

1. Outer Metal Sheets

The external facings protect the insulation core and contribute to the panel’s surface finish, durability and structural performance.

2. Insulation Core

The insulation core helps control heat transfer. Its material and properties determine important performance characteristics.

3. Jointing System

The panel joints connect individual sections and help maintain the continuity of the insulated building envelope.

Common Sandwich Panel Core Materials

• PUF – Polyurethane Foam
• PIR – Polyisocyanurate
• Rockwool – Mineral Wool
• EPS – Expanded Polystyrene

Each material has different performance characteristics and should be selected according to project requirements, including thermal insulation, fire performance and acoustic considerations.

Who Is the Largest Sandwich Panel Manufacturer in India?

Identifying the largest sandwich panel manufacturer requires considering the type of panel being manufactured and the production capacity associated with that product category.

Manufacturers may specialise in different insulation materials, panel configurations and industrial building solutions. Therefore, production capacity should always be compared using the same product category and measurement basis.

Mount has established a large-scale sandwich PUF panel manufacturing operation at its Tumakuru facility in Karnataka.

According to its published manufacturing expansion information, the company has a reported sandwich PUF panel production capacity of 7,00,000 square metres per month following the commissioning of its second fully automated continuous production line.
