Polyurethane sandwich panels

Sandwich panels are rapidly gaining popularity thanks to their affordable price and excellent performance. They are as strong as traditional building materials, yet much lighter. On a whole range of parameters, sandwich panel structures clearly outperform buildings made of brick and concrete blocks.

One of their main advantages is that construction can go ahead at any time of year. The panels have a neat appearance, a wide choice of facing-sheet colours and a variety of trim elements that give the building a finished, attractive look. As a result, additional interior and exterior finishing is usually not needed.

Mobility and lower transport costs

Easy transport is a major advantage of sandwich panels over other building materials. Delivering one square metre of such a wall costs up to 40 times less than delivering reinforced concrete or brick. What is more, a sandwich panel structure can be dismantled when needed, moved and reassembled at a new site.

Fast construction

Because the panels are light, a heavy foundation is not required — a lighter one is enough, which saves both time and money. The low weight and factory-ready elements allow the building to be assembled quickly, even without heavy lifting equipment.

Low thermal conductivity

According to calculations, a 100 mm sandwich panel provides the same thermal insulation as:

• 525 mm of timber;
• 600 mm of foam concrete;
• 1010 mm of expanded-clay concrete;
• 2300 mm of brick;
• 4500 mm of concrete.

Thanks to this, heating and air-conditioning costs of a sandwich panel building drop many times over. Thinner walls also increase the usable floor area. Sandwich panels are used as well for additional insulation and renovation of the facades of existing buildings.

Reliable and hygienic

The metal facing layers with a protective polymer coating keep out rodents and prevent fungus and mould. The panels resist chemical environments and aggressive biological influences, and they keep their properties under sharp temperature changes and high humidity. This makes them well suited to food production, warehouses and cold rooms.

Eco-friendliness and compliance with standards

Sandwich panels comply with residential construction standards, as confirmed by sanitary and environmental certificates. That is why they are used not only in warehouses and factories but also in houses, offices and public buildings.

The panel surface is smooth and easy to clean, which makes it well suited to rooms with strict hygiene requirements — food production, cold rooms, medical and laboratory spaces. The polymer coating keeps its colour and appearance for many years.

Long service life

A building made of sandwich panels lasts more than 40 years on average. Its life is extended further by easy repair: if damage occurs, only the individual panel needs replacing, not the whole wall.
