In the rapidly evolving world of construction, efficiency is no longer just a “plus”—it is a necessity. Whether you are building a cold storage facility, a commercial warehouse, or a prefabricated home, the materials you choose dictate your long-term costs and structural integrity.
At Astar Insulation, we believe in providing solutions that balance durability with thermal excellence. That is why Sandwich PUF (Polyurethane Foam) Panels have become the gold standard for modern building envelopes.
A Sandwich PUF Panel is a structural material composed of a rigid core of polyurethane foam sandwiched between two layers of galvanized or pre-painted metal sheets (usually steel or aluminum).
This “sandwich” design creates a lightweight yet incredibly strong component that offers superior thermal insulation compared to traditional brick-and-mortar or simple metal roofing.
The primary reason industries switch to PUF panels is their exceptionally low thermal conductivity. By maintaining internal temperatures, these panels significantly reduce the load on HVAC systems, leading to energy savings of up to 40-50%.
Time is money. Since PUF panels are prefabricated, they are ready to be installed the moment they arrive at the site. This can reduce construction timelines by weeks or even months compared to traditional masonry.


Modern PUF panels are engineered with fire-retardant properties. Additionally, their tongue-and-groove interlocking systems ensure a leak-proof, airtight seal that protects against extreme weather conditions.
Despite being lightweight, these panels offer high load-bearing capacities, allowing for wider spans in roofing and walling without the need for heavy internal support structures.
When choosing a panel, it is important to understand the technical parameters that fit your specific climate and structural needs:
| Feature | Specification Range |
| Core Density | 40 kg/m³ (± 2 kg/m³) |
| Panel Thickness | 30mm to 150mm |
| Thermal Conductivity | ~0.023 W/mK |
| Temperature Range | -80°C to +80°C |
| Facing Material | PPGI, Stainless Steel, or Aluminum |
At Astar Insulation, we don’t just supply materials; we provide peace of mind. Our Sandwich PUF Panels are manufactured using high-precision technology to ensure uniform density and perfect interlocking.
