Sandwich Panel Manufacturer in Bangladesh — EPS, PU & Rockwool

EPS panel are not fire-proof in the sense of being non-combustible, but they are self-extinguishing: the core carries a Class B / Class 2 fire rating under EN 14509:2013, meaning it burns while a flame is applied but does not sustain combustion once the source is removed. For buildings where insurance conditions or building codes require a non-combustible core, Rockwool (Class A2) is the correct specification.

EPS Sandwich Panel last 30–40+ years when installed properly. The expanded polystyrene core is dimensionally stable and does not rot, and the galvanised steel skins resist corrosion. Proper installation — correct fastener spacing, sealed joints and compatible trims — is the main factor in achieving full service life. RPS Construction panel are manufactured to EN 14509:2013 specifications.

Yes. Panel are available in white, cream, blue, and red as standard colours, with any RAL colour available on request. Custom lengths and thicknesses (50 to 150 mm) are manufactured to order. Panel dimensions, skin gauge and coating can all be specified to match your project requirements. RPS Construction handles full custom manufacturing for projects across Bangladesh.

A Sandwich Panel is a prefabricated building component consisting of two steel skins bonded around an insulation core — EPS (expanded polystyrene), PU (polyurethane), or Rockwool (mineral wool). The composite structure provides thermal insulation, structural rigidity and weather protection in a single factory-made panel. Sandwich Panel are installed for walls and roofs of factories, warehouses, cold storage facilities and commercial buildings across Bangladesh, constructed far faster than traditional brick and concrete methods.

PU (PUF) Sandwich Panel are the best choice for cold storage — their closed-cell polyurethane foam core has the lowest thermal conductivity of all three cores (0.022 W/mK), providing maximum insulation per millimetre of panel thickness. PU panel are cold-store safe from -50°C to +110°C, resist moisture absorption better than EPS, and maintain a continuous vapour barrier. For freezers below -10°C, specify thicker PU panel to hold the temperature gradient.

Sandwich Panel pricing in Bangladesh depends on core type, thickness, skin gauge and length. EPS is the most affordable, PU costs moderately more, and Rockwool is the premium option — the price difference reflects fire rating and thermal performance gains.

Yes — insulated roof panel are a standard application of Sandwich Panel construction. Roof panel use the same three core types (EPS, PU, Rockwool) as wall panel, with the same thermal and fire performance characteristics. RPS Construction supplies and installs roof panel nationwide for factories, warehouses, workshops, and commercial buildings across Bangladesh. Roof panel are typically installed with ridge capping and flashing for a complete weather seal.

Yes — Rockwool Sandwich Panel are fire-proof. The mineral wool core is non-combustible (Class A2 under EN 14509:2013), meaning it does not ignite, burn, or release toxic smoke when exposed to fire. Rockwool panel carry up to EI 120 fire resistance (120 minutes of fire integrity and insulation), making them the safest choice for buildings with escape routes, high-occupancy halls, or insurance conditions demanding a fire-proof core. They also provide excellent acoustic insulation at approximately 31 dB sound reduction.
