Insulated Panels for Prefab Modular Buildings

Sandwich panels are a type of composite material with a metal surface (galvanized steel/aluminum/color coating) and an insulating core (PU, rock wool, or EPS).

- Use for: walls, roofs, cold storage, cleanrooms, warehouses.
- Thickness: 50 mm, 75 mm, 100 mm, 150 mm, 200 mm available.

What Is a Sandwich Panel?

A sandwich panel consists of three layers: two metal skin layers (typically galvanized steel or aluminum) sandwiching a low-density core material (polyurethane, rock wool, or magnesium oxysulfide).

This construction provides lightweight, high strength, good thermal insulation, and fire resistance, making it ideal for energy-efficient buildings. Here are the benefits:

- Fire Safety: Class B1 to A1 fire rating
- Thermal Insulation: 0.019-0.035 W/mK conductivity
- Waterproof: ≤3% moisture absorption
- Lightweight: 42-45 kg/m³ density
- Fast Installation: Pre-cut panels, no additional insulation needed
