PUF Wall Sandwich Panels
The most widely used insulated panel in Indian construction, and for good reason. Polyurethane foam delivers reliable thermal insulation at a price point that makes large-scale projects viable. Manufactured on a continuous press line at our Derabassi facility. Proven across thousands of buildings. If your project needs solid insulation without the premium of PIR, this is the panel to specify.
The Short Version
When PUF is the Right Call
Not every project needs PIR. That is the honest answer. If your building is a standard warehouse, an industrial shed, a logistics facility, or a chiller room operating above minus 20 degrees, PUF will do the job and save you money doing it. The thermal performance is excellent. The installation is identical. The panel comes off the same continuous press line at Derabassi with the same quality control. Where PIR wins is fire performance and extreme low-temperature stability. Where PUF wins is value. For the majority of industrial and commercial projects across India, PUF is the specification that makes engineering and financial sense.

Before You Order
Specification Checklist
Most specification mistakes happen early. Wrong thickness for the temperature delta. Wrong fire class for the occupancy type. Wrong coating grade for the site conditions. Use this checklist before you freeze your bill of quantities.
What to Lock Before You Order
- Match panel thickness to your actual temperature requirement. For PUF, add 10 to 15% extra thickness compared to PIR for the same U-value.
- Choose facing material for your actual environment. PPGI for standard industrial. Stainless steel where washdown or food contact applies.
- Pick coating by exposure. PE for inland sites. SMP for durability. PVDF for coastal or chemically aggressive atmospheres.
- PUF carries standard fire ratings. If your insurer or occupancy type requires enhanced fire performance, discuss PIR or Rockwool alternatives with our team before ordering.
- Request NABL-certified thermal conductivity test data with the quotation. Our PUF panels are tested at 0.024 W/m·K. Verify this matches what you specify in the tender.
After Installation
- Walk all joint lines and flashings after every monsoon season. Sealant failure is the most common leak path.
- Clean panel surfaces with mild detergent only. Abrasive cleaners cut through the coating and shorten its life.
- Re-check fastener torque every two years on exposed roofing panels.

Questions
Before You Specify
The questions our engineering team gets asked most by architects, procurement teams, and cold storage contractors.
What thickness of PUF panel do I need for cold storage?
Chiller rooms (0°C to +5°C) typically need 60 to 80mm in PUF. Standard cold rooms (-18°C to 0°C) need 100 to 120mm. For deep freeze below minus 20°C, we recommend either 120 to 150mm PUF or switching to PIR panels which achieve the same insulation at a thinner profile. Our team will calculate the exact requirement for your temperature and location.
Can PUF panels be used for pharmaceutical clean rooms?
Yes, for standard clean room applications. PUF panels with smooth GI or stainless steel facings meet basic GMP surface requirements. For facilities requiring enhanced fire ratings as part of the GMP specification, we would recommend PIR panels instead. Our team can advise based on your specific regulatory requirements.
Should I choose PUF or PIR for my project?
PUF is the right choice when your project needs solid thermal insulation at a competitive price and does not require enhanced fire performance. That covers the majority of warehouses, industrial buildings, logistics facilities, and standard cold storage above minus 20°C. PIR is the better choice when fire safety is a primary requirement, when you need to minimise panel thickness, or when operating below minus 25°C. We manufacture both on the same line at Derabassi and will recommend honestly based on your actual needs.
What is the lead time?
Standard lead time for PUF wall panels is 2 to 3 weeks from confirmed order. PUF panels are our highest volume product, so availability is generally faster than PIR or Rockwool. Custom RAL colours may add 1 week. Contact our team for urgent requirements.
Do you deliver and install across India?
We deliver across all states from our Derabassi facility. Installation teams available on request. Handover includes as-built documentation, test certificates, and installation records.
What certifications do ACE PUF panels carry?
ISO 9001:2015 quality management. NABL-accredited thermal testing. Eurofins-certified fire resistance. Defence approvals for government and MoD projects. Every one independently verified.
