High-Quality PU Sandwich Panel for Insulation & Construction

Construction technology

What is a PU Sandwich Panel?

A PU (Polyurethane) Sandwich Panel consists of a high-performance rigid polyurethane foam core bonded between two layers of pre-painted galvanized steel (PPGI) sheets. This advanced composite panel delivers the highest thermal insulation efficiency among all Sandwich Panel types, making it the preferred choice for energy-critical applications.

The closed-cell PU foam core provides exceptional thermal resistance with minimal thickness, while the steel outer layers ensure structural rigidity and weather protection. Panels are available in thicknesses from 40mm to 150mm and can be manufactured in custom lengths up to 12 meters.

  • Pre-painted galvanized steel (PPGI) outer layers
  • High-density rigid polyurethane (PU/PUR) foam core
  • Thickness options from 40mm to 150mm
  • Standard 1 meter width, up to 12 meters long
  • Steel sheet thickness 0.4mm to 0.6mm
  • Thermal conductivity of 0.022 W/mK — best in class

Key advantages

Key Features of PU Sandwich Panels

Best Thermal Insulation

PU foam has the lowest thermal conductivity (0.022 W/mK) of any insulation core, reducing energy costs by up to 60% compared to traditional materials.

High Structural Strength

The rigid foam core provides excellent compressive strength while remaining lightweight, supporting large-span wall and roof applications.

Energy Efficient

Outstanding insulation performance lowers HVAC running costs significantly, delivering long-term savings for cold storage and climate-controlled facilities.

Fire Retardant Options

Available with fire-retardant additives and B1/B2 fire ratings for safer construction in sensitive projects and public buildings.

Moisture and Chemical Resistant

Closed-cell PU structure resists water absorption and chemical exposure, ensuring long-term durability in harsh environments.

Quick Installation

Precision-engineered tongue-and-groove joints allow fast, secure panel assembly, reducing labor time and construction costs.

How we work

Our Manufacturing Process

1

Steel Sheet Preparation

PPGI or PPGL steel coils are cut, shaped and pre-treated for optimal bonding with the PU foam core.

2

PU Foam Injection

Polyol and isocyanate components are precisely mixed and injected between the two steel sheets.

3

Continuous Lamination

The panel passes through a double-belt laminator where the PU foam expands and bonds under controlled pressure and temperature.

4

Curing and Formation

The injected PU foam cures in place, creating a rigid closed-cell core with uniform density and bond strength.

5

Precision Cutting

Continuous panels are cut to the exact length specified by the project requirements.

6

Quality Inspection

Each panel is checked for dimensional accuracy, bond integrity, surface finish and thermal performance.

7

Packaging and Delivery

Approved panels are bundled, protected and delivered to project sites across Bangladesh.

Premium insulation panels � factory-direct pricing from RPS Construction

PU (Polyurethane) sandwich panel prices in Bangladesh are higher than EPS but deliver significantly better thermal insulation � making them the preferred choice for deep-freeze facilities, pharmaceutical cold chains, and food processing plants where temperature precision is critical.

Pricing factors: Panel thickness (40mm�150mm), steel skin specification (PPGI, Galvalume, or Stainless Steel), isocyanate density, and project volume. PU panels offer long-term energy savings that offset the initial investment within 2�3 years of operation.

FAQ

Frequently Asked Questions

What is the price of PU sandwich panel in Bangladesh?
PU sandwich panel prices in Bangladesh range from BDT 650 to BDT 1,200 per square foot depending on thickness, steel specification, and order quantity. PU panels cost more than EPS but offer 30�40% better thermal insulation � resulting in significant energy savings for cold storage and freezer applications.
How does PU compare to EPS for insulation?
PU foam has a thermal conductivity of approximately 0.022�0.028 W/m�K, compared to EPS at 0.035 W/m�K. This means a 100mm PU panel provides insulation equivalent to approximately 140mm EPS � making PU the superior choice when space is limited or extreme temperatures must be maintained.
What is the R-value of PU sandwich panels?
A 100mm PU sandwich panel achieves an R-value of approximately R-4.5 to R-5.0 (IP units) or U-value of 0.22 W/m��K. This exceptional thermal resistance makes PU panels ideal for deep-freeze facilities maintaining temperatures of -25�C to -40�C.
Are PU panels suitable for deep freeze applications?
Absolutely. PU sandwich panels are the industry standard for deep-freeze storage (-25�C to -40�C), ice cream factories, frozen fish storage, and pharmaceutical cold chains. The closed-cell PU structure prevents moisture ingress and maintains consistent temperature � critical for product quality and safety compliance.
What steel thickness is used in PU panels?
RPS PU sandwich panels use 0.4mm to 0.6mm pre-painted galvanized steel (PPGI) or Galvalume steel skins. The steel is bonded to the PU core under high pressure, creating a composite panel with excellent structural rigidity and weather resistance.
Do you offer PU panel installation service?
Yes. RPS Construction provides complete installation support across Bangladesh. Our experienced installation teams handle panel fixing, sealing, flashing, and cold-room door installation. We also provide technical guidance for contractors who prefer to handle installation in-house.
