Quick answer
What is a pir fire-retardant panel?
Polyisocyanurate (PIR) is a tougher chemical cousin of PUF. It chars rather than melting, so it behaves better in fire. Insurers and fire consultants often specify it for food plants, pharma and large warehouses.

Why this panel
What you get
1
Chars instead of melting
PIR forms a protective char layer and spreads flame less than standard PUF.
2
Same thermal class
k is roughly 0.022 W/mK, so thickness choices match PUF.

We send the maker’s fire test documents with the quote. Check them with your consultant.
Continuous family: made on a continuous line, tongue-and-groove edge, cut to length. Typical; varies by brand. Continuous or cam-lock?

What thickness does the pir fire-retardant panel come in?
Commonly 50, 60, 80, 100, 120, 150 mm (typical; varies by brand). Continuous panels are cut to length on the line.
What is the U-value of a 100 mm pir fire-retardant panel?
About 0.21 W/m²K, calculated for the core with k ≈ 0.022 W/m·K: U = 1 / (0.13 + d/k + 0.04). Joints, fixings and doors add heat gain in a real building.
What is the core density and skin?
Core density 40–45 kg/m³ (typical; varies by brand). Skins: Coated steel 0.45–0.6 mm (typical). Cover width 1000–1200 mm cover width.
Is the pir fire-retardant panel fire rated?
Classification depends on the brand and the test standard (for example EN 13501-1 or FM approvals). Ask for the certificate. We never assume one.
What is the price of the pir fire-retardant panel?
The panel rate depends on thickness, skin gauge and coating, core, brand and quantity, so we quote today’s rate per brand for your specification. Transport is extra and quoted separately for your pincode; flashing is made as per your requirement.
Where is the pir fire-retardant panel used?
Food processing halls; Pharma and FMCG warehouses; Cold stores where insurers ask for PIR; Fire-compartment partitions (tested systems only).
Rates move with steel and chemical prices, so we quote fresh every time, with every available brand on one sheet. Transport is extra and quoted separately.
