Types Of Puf Sandwich Panels

Types of PUF Sandwich Panels We Offer

We offer a wide range of panel configurations to match specific project needs. Here’s a look at the different panel types we manufacture, along with their technical specifications and ideal use cases.

Panels Specifications

Sandwich PUF Panel Manufacturing Technology

At EPACK Prefab, we manufacture high-performance PUF (Polyurethane Foam) and PIR (Polyisocyanurate) insulated sandwich panels using advanced continuous and discontinuous production lines. Each panel consists of a rigid foam core sandwiched between high-quality facings such as pre-painted galvanized steel (PPGI/PPGL), stainless steel, or galvalume sheets, ensuring strength, insulation, and long-lasting performance.

Our state-of-the-art panel lines guarantee precision, automation, and strict quality control, making EPACK one of the leading panel manufacturers in India.

Common queries

PUF (Polyurethane Foam) Sandwich Panels are insulated construction panels made of a rigid PUR/PIR foam core between two metal facings. They provide thermal insulation, fire resistance, durability, and faster installation compared to traditional building materials.

Both are high-performance insulating cores:

  • PUF (Polyurethane Foam): Excellent thermal insulation at affordable cost.
  • PIR (Polyisocyanurate): An advanced version of PUF with better fire resistance and lower thermal conductivity (K-value).
    EPACK offers both options so clients can balance cost, insulation, and fire safety.

We manufacture:

  • Single Groove Wall Panels – General purpose walls & partitions
  • Double Groove Cold Storage Wall Panels – Airtight, heavy-duty cold rooms & freezers
  • Hidden Screw Wall Panels – Smooth finish for clean rooms, labs, hospitals
  • Roof Panels – Structural strength, overlap joint for leak-proof roofing
  • Camlock Panels – Interlocking panels for cold rooms & high hygiene applications

PUF/PIR panels are available in 30mm to 150mm depending on the type:

  • Single Groove Wall Panels: 30–60mm
  • Double Groove Cold Storage Panels: 60–150mm
  • Hidden Screw Panels: 50–60mm
  • Roof Panels: 30–120mm
  • Camlock Panels: 40–150mm

Panels are available in widths ranging from 900mm to 1200mm (commonly 1000, 1050, 1100, 1150, and 1200mm). Custom widths are possible for bulk orders.

EPACK panels are used in:

  • Warehouses & industrial sheds
  • Cold rooms & freezer chambers
  • Food processing & pharmaceutical facilities
  • Clean rooms & laboratories
  • Modular offices & site cabins
  • Prefabricated schools, hospitals & institutional buildings

For cold chain applications:

  • Double Groove Panels → Stronger joint, better thermal seal for large facilities.
  • Camlock Panels → Airtight interlocking system, best for smaller cold rooms & walk-in freezers.

Yes. PIR-core panels have higher fire resistance compared to standard PUF. EPACK panels comply with Class 1/Class 0 fire ratings as per relevant standards. For stricter codes, Rockwool Panels are recommended.

Yes. The metal facings and sealed joints prevent water ingress. Roof panels use an overlap joint system to ensure leak-proof performance in heavy rain.

PUF/PIR panels have a low thermal conductivity (around 0.023 W/m·K), reducing HVAC loads and saving up to 40–50% energy costs in temperature-controlled buildings.

With proper installation and minimal maintenance, PUF/PIR panels can last 20+ years, retaining their insulation and structural properties.

Yes. EPACK provides customization in:

  • Thickness & width
  • Rib profiles (Standard, Micro, Wave)
  • Core type (PUF/PIR/PU)
  • Surface finishes (PPGI, PPGL, Galvalume, Stainless Steel)
  • Colors & special coatings (PVDF etc.)

  • PUF/PIR Panels: Superior thermal insulation, higher fire safety, longer life.
  • EPS Panels: More economical, lighter, but lower insulation & fire performance.
    Choice depends on budget, thermal requirement, and safety compliance.

Yes. EPACK’s PUF/PIR Roof Panels are specifically designed with trapezoidal ribbing and overlap joints for strength, water runoff, and weather protection in industrial & commercial roofing.

Panels are installed using interlocking joint systems (groove, overlap, or camlock). Our technical team provides detailed installation guides and recommends certified installation partners for large projects.

With a production capacity of 1,400 SQM per day, EPACK ensures fast delivery. Orders are usually dispatched within 7–14 days depending on size and customization.

We specialize in manufacturing & supply, but we work with a network of certified installation partners across India and provide technical support to ensure proper installation.
