Sandwich Panel Manufacturer in India — Compare the Five Cores and Choose Right

A sandwich panel is an insulated building board made of two steel facing sheets bonded to a lightweight core, so one board gives you structure, insulation and a finished surface together. SAMAN manufactures sandwich panels in five cores — PUF, PIR, EPS, Rockwool and Glass Wool — at our Bangalore and Greater Noida factories, for walls, roofs, cabins and cold rooms across India.

Most buyers do not arrive knowing which core they need. They know the problem — heat coming through a shed roof, a cold room that will not hold temperature, a fire-rating clause in a tender, a wall that has to go up fast — and they need the panel that solves it without paying for performance they will never use. This hub exists to make that choice clear, then send you to the exact material page for specifications and price.

What is a sandwich panel?

A sandwich panel — also written "sandwitch panel", and sold as an insulated panel or insulated sheet — is a three-layer board. Two thin metal facing sheets sit on the outside; a low-density insulating core sits in the middle; the core is bonded to both facings so the three layers act as one stiff, self-supporting board. That layered build is where the name comes from.

The outer facings carry the finish, the weather resistance and most of the strength. The core carries the insulation — how well the panel blocks heat, cold, fire or sound. Change the core and you change what the panel is good at, which is exactly why the same-looking board comes in five very different materials.

Because the panel arrives finished on both faces, there is no separate insulation, cladding or lining step on site. You fix the panel and the wall or roof is done — which is why sandwich panels put up buildings far faster than block-and-plaster or single-skin sheeting with loose insulation.

Types of sandwich panels — the five cores we manufacture

The facings barely change between products; the core is the real decision. Here is what each core is known for and where it fits. For exact density, thermal, fire and acoustic figures — and price — open the material's own page.

Roofs. As a roof cover, the panel keeps heat out of the space below — the single biggest reason factories, warehouses and workshops in Indian conditions choose insulated panels over bare single-skin sheeting. Roof panels use a profiled top facing and a lapped, weather-tight joint.

Cabins and porta units. The same board forms the walls and roof of porta cabins, site offices and security cabins, giving insulation and finish without a separate lining.

Cold rooms and freezers. For temperature-controlled stores, the panel is the thermal envelope, usually with a cam-lock joint so panels lock airtight. Core choice and thickness matter most here.

Sizes, thickness and facing options

Sandwich panels are made across a wide thickness range so the panel matches the thermal or fire duty of the job rather than a one-size board.

On every batch we check facing gauge, panel thickness, core rise or density, and the tongue-and-groove profile so joints close cleanly and the panel sits flat. Panels are edge-protected, stacked and bundled for dispatch from the nearer of our two factories. Making the panel ourselves — rather than buying and reselling — is why we can match core, facing, thickness and length to your job instead of offering only what is in stock.

How to choose the right sandwich panel

Work from the problem, not the product:

• Leading with cost and light thermal load? EPS is the budget core.
• Need strong thermal insulation for cabins, cladding or cold rooms? PUF is the all-round default.
• Fire performance and higher heat together? PIR is the premium thermal core; Rockwool is the mineral fire-and-acoustic core.
• Fighting noise? Rockwool or Glass Wool bring acoustic control a foam core does not.
• Roof vs wall? Same core, different facing profile and joint — tell us which face is exposed.

Then set thickness to the duty and facing to the environment (stainless or aluminium for hygienic cold rooms and food spaces; PPGI or PPGL for general wall and roof). If a tender specifies a fire class or a temperature, send it with your enquiry and we will confirm the core, thickness and any tested value at quotation.

Delivery, warranty and quotation

We manufacture and dispatch pan-India: Bangalore for South India, Greater Noida for North India and Delhi NCR. Default dispatch is 3–5 business days on standard products; transport is confirmed at quotation, and a 500 m² minimum billing applies to long-distance dispatch. See our Delivery Policy for the full terms.

Panel warranty is 5–10 years, confirmed at quotation. Quotes are supply-only unless stated otherwise, and any tested performance value for a specific core is confirmed at quotation rather than stated as a blanket claim. Standard products carry 7-day returns (3-day on custom) — see our Refund & Return Policy. All sandwich panels fall under HSN 940690 for GST and RFQ purposes.

Why buy sandwich panels from a manufacturer, not a trader

A trader sells you whatever core and thickness is already in the warehouse and marks it up. As the manufacturer, we cut the panel to your job — core matched to your fire, thermal, acoustic or budget need, facing matched to your environment, thickness matched to the duty, and length matched to what your site can actually receive. You get one point of accountability from quote to dispatch, real factory QC on every batch, and two dispatch origins so freight is shorter to most of the country. When a specification has to be met and proven, that direct line to the line that made the panel is the difference.
