PU Sandwich Panel
Improved Insulator for Temperature-Sensitive Applications
Designed to be optimally thermal efficient, fire safe, and sanitary. The best option among cold storage, food processing, and pharmacies in Bangladesh.
Introduction to PU Sandwich Panels?
When you want the best thermal performance and safety for your building development, standard or regular insulation cannot be relied upon. For areas where temperature control matters most such as cold storage areas, food processing areas, and clean rooms for drugs—Polyurethane (PU) Sandwich Panels are the industry’s best option.
We at Sandwich Panel Technology are a reliable PU sandwich panel company in Bangladesh. Our focus at Sandwich Panel Technology is the construction of high-performance PU panels that provide high-quality insulation, good fire protection, and clean finish. This page will explain why PU panels are the perfect choice for your custom project.
What is a PU Sandwich Panel?
PU Sandwich Panel is a rigid construction panel made up of three layers
Two Outer Layers (Skins)
These are made from tough galvanized steel sheets that have a protective-colored coating (usually PVDF or HDPE). This helps them resist rust, weather damage, and makes them easy to clean.
Inner Core
The inner core is a rigid foam in the form of Polyurethane (PU). It forms the inner core which gives the panel good strength and insulating properties.
Think of it as a strong shield. The tough steel outside makes it last a long time, while the thick PU foam inside stops heat from passing through, helping to keep temperatures steady.
Key Features and Benefits of Our PU Panels
Why you should opt for our PU panels for construction in Bangladesh? The following are the strong positives
Excellent Insulation and Energy Efficiency
PU foam is the ultimate insulator as it doesn't permit warm air to flow freely. Our panels don't permit heat to flow through, and your cold room or controlled area holds the right temperature while consuming less power. This means you end up paying much less for electricity for your refrigeration and air conditioning.
Excellent Fire Resistance
Safety is very important. Our PU panels have a better fire rating than regular EPS panels. The core material can stop burning on its own and is made to slow down flames, giving more time for safety actions if there is a fire. To ensure the best safety, we also have fire-retardant options available.
Lightweight and Convenient to Install
Lightweight despite higher strength and better insulation, PU panels offer ease and quick handling and construction when compared to conventional construction materials. Construction time and labor expenditure are lowered significantly. Your facility can be put to use very much earlier.
High Structural Strength
The connection between the rigid PU foam and the steel skins produces a very rigid and stiff panel. This provides the opportunity for the span between supports to be larger and the ability for the structure to be able to resist different loads and stresses.
Hygienic and Easy to Clean
The smooth, non-porous surface of the steel and the tight joints make PU panels perfect for places where cleanliness is very important. They are simple to clean and disinfect, stopping the growth of bacteria and mold, which is necessary for food and medicine industries.
Environmental Sustainability
PU foam nowadays is made to be eco-friendly. It generally uses blowing agents that are not harmful to the ozone layer. It is very good energy-efficient feature also helps to reduce the amount of carbon emissions in the life cycle of the building.

Often Asked Questions
What makes PU panels different when compared to EPS panels?
PU panels contain a denser foam core offering much better thermal insulation (a lower K-value) and better fire resistance than EPS panels. They represent the high-end option for mission-critical environments.
How long does a PU panel last for?
Our PU panels if installed and maintained properly can last for a very long period of time, typically 40 years or more since they are moisture resistant and feature sturdy steel faces.
Can you do custom sizes?
Yes, you can actually create the panels at different widths and different liftoff widths to accommodate the custom design of your project.
Are the PU panels applicable to exterior walls?
Yes, they are perfect for exterior walls and roofs, providing a completely insulated structure.
Are maintenance services available?
Even though the panels are low maintenance in nature, we do offer suggestions and support for cleaning and maintenance for long term performance.
