Continuing population growth, urbanization, and rising CO2 emissions: those are three of the global trends making sustainable technologies for the construction sector imperative. Hightech materials from Covestro advance such technologies in various ways.

Our materials protect both existing and emerging structures against a multitude of environmental influences, thereby reducing the amount of maintenance required and increasing the buildings’ lifespan. On top of that, they ensure a significantly improved energy footprint thanks to unmatched insulation properties. Finally, architects and building owners profit from unique opportunities in terms of design and functionality.

During its life cycle, polyurethane foam saves 70 times more energy than its production requires.


From large-scale consumer to passive house

Werkstoffe von Covestro fördern zukunftsweisende Dämmlösungen für Millionen von Gebäuden überall auf der Welt.

40 percent of the global energy consumption and around one third of the global CO2 emissions are caused by the millions of private, public, and commercially used buildings around the world. A heavy burden both for our climate and economy – and, at the same time, a huge opportunity for improvement by means of forward-looking insulation technologies.

Unmatched insulation: polyurethane foams

Covestro produces the components for polyurethane foams that rank among the most efficient and versatile insulating materials available. Compared to other materials used for this purpose, such as expanded polystyrene or mineral wool, the insulating effect is up to 40-percent higher. We do not content ourselves with this excellent result, however, but continuously refine our components to make them even more efficient – for example by reducing the size of the foams’ pores.

The great insulating performance of polyurethane is due to its low heat conductivity. Aside from that, the material features a number of additional benefits making it the ideal choice both for the housing industry and for commercial constructions. One such benefit is the foams’ versatility when it comes to possible fields of application:

  • They can be used in virtually all parts of a building, for example walls, floors, ceilings, and back-ventilated rainscreen claddings.
  • Window frames with a core made of polyurethane rigid foam offer high heat insulation and strong protection against environmental influences.
  • As spray foam, polyurethane is easy to insert in confined, intricate structures.
  • So-called sandwich elements, in which the material is framed with light metal tracks, are especially well suited for walls of industrial buildings, such as refrigerated warehouses or exhibition halls. Covestro also works on bringing those advantages to the private building sector – thus making possible the construction of sustainable houses with passive house standard that are affordable and quickly built.
Convincing in the long run: added benefits of polyurethane

Wherever polyurethane foams are applied, the material always cuts a fine figure thanks to its compactness. Achieving high levels of insulation even in small spaces, it allows the construction of slimmer walls. This extends the living space available inside the building and improves the appearance of building facades.

Once applied, building owners and residents can rely on the many benefits of polyurethane foams in the long run: they age slower than other insulating materials, absorb sound when applied in multiple layers, and show good resistance against physical impact, flames, heat and cold, wetness, and mold formation.

The protection of surfaces is vital for a building’s lifespan.

Surface treatment

A sustainable basis for tough surfaces

Covestro is redefining standards in innovative surface treatment.

Be it under the open sky or inside of buildings, be it in private homes or in industrial facilities: the protection of surfaces is vital for a building’s lifespan. Coatings, adhesives and sealants based on raw materials by Covestro boost the durability of floors, walls and ceilings. At the same time, our materials become more and more sustainable. Learn how Covestro is redefining standards in innovative surface treatment.

Smooth protection for crowded places: interior coatings

The interiors of buildings are exposed to a multitude of harmful influences over a long period. Coatings based on our high-quality polyurethanes reliably protect floors and walls against abrasion, liquids and chemicals. They withstand heat and cold, enhance and conserve the beauty of underlying surfaces and allow easy cleaning and maintenance. And most important: our materials for concrete floors allow a quick return to operation for building owners and increases efficiency for contractors. What’s more, Covestro offers building owners and service contractors novel opportunities regarding the sustainability of the materials used: aside from raw materials based on conventional solvents or for solvent-free systems, our portfolio also includes innovative, water-borne coating components.

Not only coatings, but also adhesives or sealants based on polyurethanes provide strong advantages for the building & construction industry. Parquet flooring, for instance, can be installed very efficiently on virtually any surface using the right adhesive based on silane-terminated polyurethanes.

Polyurethane also offers orientation to those who need it. Floor guidance systems can be a great help to people with visual impairments. Covestro has developed a material solution for such products based on thermoplastic polyurethane. A pattern of bumps just a few millimeters high improves navigation for people with visual impairments.

Less layers, more efficiency: corrosion protection for industrial facilities

For the heavy-duty protection of large infrastructures, Covestro has developed a solution that sets a new standard in the industry. Our polyurethane-based, polyaspartic coating technology named PASQUICK helps guarding plants, bridges, wind energy towers and other facilities against corrosion and weathering even in the harshest conditions. It defies salt water as well as strong winds, extreme temperatures and aggressive chemicals. The technology’s groundbreaking advantage lies in its efficiency: it offers at least the same level of protection as any traditionally used product, but with one less layer of coating to apply. This saves time and money for asset owners, contractors and the public purse.

The demands on today’s buildings are higher than ever before: efficiency, sustainability and design have to be met at once.

Design and lighting

Highlights for a modern architecture

Polycarbonates by Covestro enrich the world of future-looking architecture.

Efficiency and sustainability are not the only goals in today’s construction industry. An attractive, inventive and functional design for new buildings is just as important. Polycarbonates by Covestro bring all these traits together. Learn how the material enriches the world of future-looking architecture.

Colorful opportunities: polycarbonate as construction material

Polycarbonate lends itself to structures that stand out from the ordinary. It is extremely robust yet light, easy to shape, and available in a multitude of colors, as well as in a high-class transparent look. By making optimal use of these qualities, architects create spectacular looking roofs and facades for large public buildings, such as stadiums, railway stations, and airports. What’s more, the constructions shield visitors from wind, rain, and UV rays without blocking the light shining in. Polycarbonate, however, is not restricted to a city’s architectural highlights. It also serves well in smaller scale, for instance as building material for private carports and greenhouses.

Lighting the way: Polycarbonate LEDs

Polycarbonate is the base material for LED lenses that spend less energy and are more durable than those made from glass. This makes it the perfect choice for modern lighting technology inside and outside of buildings. Thanks to their clarity and heat resistance, polycarbonate LEDs also add comfort and safety to living environments. Finally, the good formability of polycarbonate allows for extraordinarily slim geometries and, thus, for an optimal diffusion of light.
