What is a sandwich panel? The benefits of bio-composite sandwich panels.

Sandwich panels are a revolutionary solution for the modern construction industry, and at Duplicor® we have taken this technology to the next level with our bio-composite sandwich panels. But what exactly are sandwich panels, and why should you choose Duplicor®'s composites as your material? In this article, we dive deeper into sandwich panels, their applications and the unique benefits of Duplicor®'s bio-composite sandwich panels.

What are sandwich panels?

A sandwich panel is a building material that consists of three layers. The two outer layers are usually made of steel, aluminum or other strong materials, while the inner layer (the core) consists of insulating material. This composition creates a lightweight panel with excellent insulating properties and high strength. Sandwich panels are widely used for facades, roofs and walls in the construction industry, especially in industrial, commercial and agricultural applications.

The outer layers protect the insulating core from external influences such as moisture, heat and cold, while the core provides thermal and acoustic insulation. Because of these properties, sandwich panels offer both structural strength and energy efficiency, making them a popular choice for modern buildings.

Duplicor®'s bio-composite sandwich panels

At Duplicor®, we differentiate ourselves from other manufacturers by using bio-composite as the outer layers for our sandwich panels. This makes our panels not only stronger and more durable, but also more environmentally friendly than traditional sandwich panels by replacing steel or aluminum. The bio-composite outer layers are made of our unique fiber reinforced composite laminate with resin extracted from plant residual waste. These outer layers (laminates) deliver very high temperature and fire resistance and are very light at very high strength. This results in a product that is both ecologically sound and technically advanced.
Our bio-composite sandwich panels not only provide exceptional insulation values, but they also contribute to the circular economy by using sustainable materials and minimizing the carbon footprint. These panels are perfect for both new construction and renovation projects, combining the benefits of energy efficiency, low maintenance costs and longevity.

Benefits of sandwich panels

The excellent thermal insulation of sandwich panels helps to reduce a building's energy requirements. This means lower heating and cooling costs, which is not only good for the environment, but also for the wallet. Duplicor® sandwich panels offer exceptional insulating properties thanks to the combination of the bio-composite outer layers with the use of ECO PET foam core material, for example. ECO PET is foam made from recycled PET bottles. With a Lambda value of 0.028 W/(m.K), we achieve thinner façade or roof structures at equal insulation values than those of traditional building elements.

One of the main advantages of sandwich panels is the speed with which they can be installed. Thanks to their light weight and modular construction, sandwich panels can be assembled quickly and efficiently, significantly reducing construction time. This makes them ideal for both temporary and permanent constructions.
Sandwich panels are robust and resistant to weather conditions such as rain, snow, wind and sun. They are also resistant to corrosion, which extends their service life. Duplicor® bio-composite sandwich panels go even further by being less susceptible to the negative effects of moisture and UV radiation. This means they require less maintenance, keeping costs low over the long term.

The use of bio-composites makes Duplicor® sandwich panels especially environmentally friendly. Bio-composite materials are made from renewable resources, contributing to lower CO2 emissions and a smaller carbon footprint. In addition, the panels are fully recyclable at the end of their useful life.
Sandwich panels can be used in a variety of building applications, from facades and roofs to partitions. They are suitable for both industrial and commercial buildings and can be customized to meet the specific requirements of each project. Duplicor® bio-composite sandwich panels also offer an excellent balance of strength, lightweight and insulating performance, making them perfect for a wide range of applications.

What are Duplicor® sandwich panels commonly used for?

Our sandwich panels are used in a variety of ways in the construction industry:
Facades: of both office and residential buildings, especially those with architecturally special designs. The combination of Duplicor® sandwich panels, produced in project-specific molds, makes the product very interesting for

What are Duplicor® sandwich panels often used for?

Our sandwich panels are used in the construction sector in various ways:

• Facades: for both office and residential buildings, especially those with a special architectural design. The combination of Duplicor® sandwich panels, produced in project-specific molds, makes the product very interesting for the often desired free design of building facades. Where they also provide thermal insulation and protection against weather conditions.
• Roofs: for both flat and sloping roofs. And with its light weight, often for roof renovation solutions, even for monumental buildings.
• Ground floor floors: for ground-level homes and/or apartment complexes. Duplicor® bio-composite ground floor floor elements are increasingly being used as a replacement for concrete, steel concrete rib or wooden floors, due to the favorable environmental cost contribution. Especially in factory homes where a lot of HSB and/or CLT wood is used for the construction of the home, our Duplicor® ground floor offers a much more favorable environmental performance calculation at the same strength, stiffness and insulation performance compared to traditionally used concrete, steel and/or wooden floors. The rot-free property then helps with application in ground floor situations above the use of wooden floors in that position in the home.

Sandwich panels are an excellent choice for modern construction projects thanks to their highly insulating properties, light weight and high strength and stiffness. Duplicor® bio-composite sandwich panels take these advantages one step further by using the combination of biobased and recycled materials, which contributes to a more sustainable and circular construction practice.
