Sandwich Panel

At Nasir & Sons Engineering Company, we are recognized as one of the leading manufacturers of polyurethane (PU) sandwich panels in Pakistan and beyond. These panels form the foundation of modern cold storage, refrigeration systems, prefabricated buildings, and industrial warehouses. Designed with advanced technology and premium materials, our PU sandwich panels provide an unbeatable combination of thermal insulation, structural strength, and long-term durability.

Each panel is manufactured through a state-of-the-art process in which polyurethane foam is injected under high pressure between two layers of pre-coated galvanized steel or stainless steel sheets. This results in a panel that is lightweight, corrosion-resistant, and highly effective in minimizing heat transfer. Compared to traditional construction methods such as concrete or brick, PU panels are thinner and lighter yet deliver superior insulation, allowing businesses to save space and significantly reduce energy costs.

Our sandwich panels are available in multiple thickness options — 50mm, 75mm, 100mm, 125mm, 150mm, and up to 200mm — to suit a wide variety of applications. With a maximum panel length of 10.6 meters, they can cover large areas seamlessly, reducing the need for joints and improving efficiency. The density of the polyurethane foam ranges from 40–45 kg/m³, ensuring consistent performance even in extreme conditions.

In addition to their insulation performance, our PU sandwich panels are designed with cam-lock joint systems and odorless silicone sealants that ensure an airtight fit, preventing any loss of cooling and enhancing the longevity of refrigeration systems. The panels are also available in a wide variety of surface finishes including color-coated galvanized steel plates, embossed aluminum, and stainless steel sheets, offering durability with an aesthetic appeal suitable for both industrial and commercial projects.
