PIR Panel — Polyisocyanurate Insulated Panels by SAMAN

Why buyers ask for a PIR panel instead of standard foam cores

Buyers move to PIR for one main reason: the project specification demands better fire behaviour or a higher working temperature than a standard polyurethane core offers. Food processing units, pharma buildings, insurer-audited warehouses and consultant-driven industrial projects increasingly write PIR into the panel schedule — sometimes by name, sometimes through a fire-performance clause that standard foam cannot satisfy.

The sourcing problem is the one every panel buyer faces, made sharper by PIR's smaller market. Most search results for a PIR panel in India are marketplace listings that show a photo and a price but not the core specification. And because PIR looks identical to an ordinary foam-core panel from the outside — same steel facings, same profile, same colour — a reseller can quote "PIR" with no way for you to verify what actually arrives on the truck. The premium you pay for PIR is wasted the moment the core is not what was quoted, and you will typically discover that only when an auditor or insurer asks for documentation you cannot produce.

The protection is straightforward: buy from the manufacturer, confirm the specification in writing at quotation, and receive the supporting datasheet or test certificate with your order. That is how we supply every PIR order. If your project does not actually need PIR's fire and temperature advantages, our standard PUF panel covers the cost-driven alternative — and we will tell you honestly which core your job needs when you share the service conditions.

Factory-made PIR sandwich panels from SAMAN

SAMAN is a manufacturer, not a trading yard. We produce insulated sandwich panels on our own lines in Bangalore and Greater Noida, so a PIR order is specified, produced and dispatched under one roof — thickness, facing, colour, profile and length are all set from your project requirement rather than pulled from stock. Running two factories also means shorter road distance to most Indian project sites, which matters more than buyers expect: long insulated panels are transport-sensitive, and every extra hundred kilometres adds handling risk and freight cost to a product that cannot be folded, cut down or repaired at site.

Because the panel is made to your order, we hold the two disciplines a PIR buyer actually needs. First, the core material you specified is the core material foamed into your panels — the foam system on the line is not interchangeable with a cheaper chemistry without us knowing it. Second, every specification we commit to is either published on this page or confirmed in writing at quotation. We do not print marketing numbers we cannot certify at delivery, and we do not quote values we cannot stand behind when your consultant asks for the test basis.

Where PIR panels are used

PIR earns its premium in buildings where fire behaviour, temperature range or an auditor's specification rules the panel choice. Four demand areas cover most of the PIR orders we quote.

Choosing the facing sheet for your PIR panel

The core decides the panel's thermal and fire character; the facing decides how it survives its environment. We face PIR panels in four materials, and the right choice is usually obvious once the duty is named:

• PPGI (pre-painted galvanised iron) — the standard choice for most walls and roofs: colour-coated, economical, and proven across Indian industrial buildings.
• PPGL (pre-painted galvalume) — chosen where the environment is harsher on steel: coastal air, chemical exposure nearby, or roofs where long-term corrosion resistance justifies the step up from PPGI.
• Stainless steel — the hygiene facing: food processing, pharma, and any wall an auditor will inspect with a swab. It costs more and earns it in exactly those rooms.
• Aluminium — selected for specific corrosion or weight requirements, typically at consultant instruction.

All facings run in 0.35–0.80 mm gauge. Tell us the environment — coastal, chemical, hygienic, or standard industrial — and we will recommend the facing honestly rather than defaulting to the costliest option.

What decides your PIR panel price

Full price tables sit on their own dedicated guide, not here — but the levers are worth knowing before you request a quotation. Thickness is the biggest driver: each step up in millimetres adds core material and cost. The PIR core itself carries a real raw-material premium over standard foam, which is the honest reason a PIR quote is never the cheapest quote on your table — and why a suspiciously cheap "PIR" quote deserves suspicion, not celebration. Facing choice moves the price next: stainless steel costs meaningfully more than PPGI. Panel length, total order quantity and delivery distance set the remainder, and made-to-order thicknesses are always priced individually at quotation.

Indicative range: ₹1,410–₹1,980 per m² for 30–80 mm at base specification — supply-only, ex-GST, excluding transport, installation and accessories; 90 mm and above, plus made-to-order thicknesses, are confirmed at quotation.

If the lowest possible panel cost is the priority and fire specification is not driving your project, PIR may genuinely be the wrong choice — a standard foam-core or EPS panel will do the thermal job for less. We would rather tell you that at enquiry than after supply.

Why a manufacturer beats a trader for PIR supply

For an ordinary panel, buying through a trader costs you margin. For a PIR panel it costs you certainty — the entire point of specifying PIR is the core, and the core is the one thing a trader cannot verify, control or document. A manufacturer controls the foam system going into the line, holds the batch record, and provides the inspection certificate at sale. That chain of custody is exactly what your consultant, insurer or auditor is asking for when the schedule says PIR. We have supplied insulated panels for leading developers and EPC contractors across India, and in every case the specification quoted is the panel produced — because the same factory answers for both.

Choosing the core — PIR against the alternatives

Every insulated panel is the same construction with a different heart. The honest, qualitative comparison — with the actual tested values for your project confirmed by datasheet or certificate at quotation:

The selection rule we give buyers: let the specification choose the core. If your project document, insurer or consultant names fire performance or elevated service temperature, PIR is the answer. If it names only a temperature to hold and a budget to meet, standard PUF is usually the honest recommendation — and if it names only "insulated enclosure, lowest cost," EPS may be. Paying the PIR premium without a specification that uses it buys margin you will never draw on.

Standard vs made-to-order thickness

Nine standard thicknesses (30–150 mm) cover the overwhelming majority of PIR projects and carry normal production lead times. The five made-to-order thicknesses — 110, 120, 130, 140 and 200 mm — are manufactured only against a confirmed order with advance payment, and their price and lead time are set at quotation. We publish that distinction because no ranking supplier does, and it changes your project planning: a standard thickness schedules tight; an MTO thickness cannot, and a contractor who discovers that after the civil work is programmed has a problem no discount fixes.

As working guidance: walls and partitions in ordinary industrial buildings sit at the lower end of the range; roofs move up a step for solar load; cold rooms are sized by the temperature gap being held, with deep-freeze duty using the top of the standard range and above. The exact thickness for your duty is an engineering answer we confirm at quotation, not a guess we print.

How we manufacture and check every PIR panel

A PIR panel is formed as one continuous process, not assembled from parts:

1. Coil feed — two facing coils (PPGI, PPGL, stainless steel or aluminium, per your spec) are uncoiled and fed into the line simultaneously, one for each face.
2. Forming — roll-forming stations set the wall or roof profile before the core is introduced.
3. Foaming — the liquid PIR system is injected continuously between the two formed facings. PIR chemistry runs at different reaction parameters from standard polyurethane, which is one reason a genuine manufacturer can tell you exactly what is in the core and a reseller cannot.
4. Curing — the foam expands and cures under a heated press, bonding to both facings so the panel behaves as one rigid board rather than a sheet with foam glued behind it.
5. Edge profiling — panel edges are cut and profiled for tongue-and-groove closure, or cam-lock on cold-room orders, so panels close tight on site.
6. Batch checks — each batch is checked for panel thickness, foam rise and facing-to-core adhesion before approval for dispatch.

What to confirm at quotation — the PIR buyer's checklist

Bring these five points to any PIR supplier, including us. The answers separate a manufacturer from a middleman in one phone call:

1. Core confirmation in writing — the quotation must say PIR (polyisocyanurate), not "insulated foam" or another vague phrase.
2. Density, k-value and fire rating basis — by datasheet or test certificate for your order, not a brochure average.
3. Thickness class — standard (30–150 mm) or made-to-order (110–140, 200 mm), because it decides your lead time and payment terms.
4. Facing and gauge — named material (PPGI / PPGL / SS / aluminium) and gauge within 0.35–0.80 mm.
5. Inspection certificate — third-party or government-authorised, provided at time of sale.

Sizes and customisation — with the real constraints

Panel length, facing colour and profile are set per order. Long panels are transport-sensitive — the practical length limit for your site is a road and unloading question as much as a production one, so we confirm feasible lengths at quotation against your delivery location and dispatch factory rather than promising a number your access road cannot receive.
