Sandwich Panel for Every Project
Understanding sandwich panels
What is a Sandwich Panel?
A sandwich panel is a composite building material made of two metal skins bonded to an insulating core. This three-layer structure delivers high strength, excellent thermal insulation, and fast installation � making it the preferred choice for industrial and commercial construction across Bangladesh.
- Steel skins: Pre-painted galvanized iron (PPGI) or aluminum, 0.4–0.6mm thick
- Insulation core: EPS, Polyurethane (PU), or Rockwool � chosen by project requirements
- Standard thickness: 40mm to 150mm, custom sizes available
- Panel width: 900mm or 1000mm standard, cut-to-length on request
- Thermal conductivity: As low as 0.035 W/m·K (EPS core)
- Fire safety: Rockwool core offers 2–4 hour fire resistance rating
Key advantages
Benefits of Sandwich Panels
Why thousands of builders in Bangladesh choose sandwich panels over traditional brick and mortar
60% Faster Construction
Prefabricated panels are installed in hours, not weeks. A 10,000 sq ft cold storage facility can be completed in 15–20 days � versus 2–3 months with traditional methods.
Superior Thermal Insulation
EPS and PU cores achieve thermal conductivity as low as 0.035 W/m·K. Maintain precise temperatures for cold storage, pharmaceuticals, and food processing � while cutting energy costs by up to 40%.
Cost Effective
Factory-direct pricing from RPS eliminates middlemen. Lower material cost, less labor required, reduced structural load � all translating to 20–30% savings compared to traditional construction.
Fire Safety
Rockwool sandwich panels are non-combustible with a fire resistance rating of 2–4 hours. Ideal for pharmaceutical buildings, food factories, and any facility requiring strict fire compliance.
Lightweight & Strong
Despite weighing a fraction of brick walls, sandwich panels offer excellent structural integrity. Reduced dead load means lighter foundations and lower construction costs.
Fully Customisable
Any thickness, any length, any steel color. RPS manufactures panels to your exact specifications � from 40mm partitions to 150mm deep-freeze walls, in any RAL color you need.
