Sandwich Panels – The Modern Solution for Fast and Efficient Construction

Sandwich panels are modern building elements made of three layers – two outer metal sheets (usually galvanized steel with a polymer coating) and an insulating core between them. This structure resembles a "sandwich," providing lightness, strength, and excellent insulation.

Production and Materials

Panels are industrially manufactured – steel is profiled, coated with a polymer layer, and combined with an insulating material such as:

  • EPS (expanded polystyrene) – lightweight and economical but with low fire resistance.

  • PUR (polyurethane) – excellent thermal insulation and long service life.

  • PIR (polyisocyanurate) – improved fire resistance compared to PUR.

  • Mineral wool (MW) – non-combustible material with great sound insulation.

After bonding under pressure, a monolithic panel ready for installation is obtained.

Sizes and Types

Standard thickness: 40–200 mm, width about 1 m, length up to 15 m.
Main types:

  • Roof panels – with drainage profiles;

  • Wall panels – smooth or micro-profiled surface;

  • Refrigeration panels – enhanced insulation for temperature-controlled rooms.

Advantages

  • Quick and easy installation;

  • Excellent thermal and acoustic insulation;

  • Long lifespan (up to 40 years);

  • Lightweight structure reducing foundation load;

  • Aesthetic appearance with over 100 color options;

  • Weather, moisture, and corrosion resistance;

  • Eco-friendly and recyclable materials.

Applications

  • Industrial buildings – warehouses, factories, production halls;

  • Commercial and public buildings – stores, sports halls, exhibition centers;

  • Modular and prefabricated houses – fast installation, good insulation, easy disassembly;

  • Cold rooms and freezers – constant temperature maintenance.

Installation and Maintenance

Panels are fixed to metal or concrete structures using self-drilling screws. Joints are sealed with silicone and profiles. Angle grinders should not be used to avoid coating damage. Maintenance is minimal – periodic inspection and cleaning.

✅ Conclusion:
Sandwich panels are an innovative, practical, and energy-efficient solution for modern construction.
