We provide best-in-class products that can be used in building insulation applications to improve insulation performance and enable increased energy efficiency.
Additives for Expanded Polystyrene (EPS) Insulation Applications
We have purposefully designed specialty carbon blacks and black masterbatch products to improve the insulation performance of EPS foam by up to 20%. Our products absorb and re-radiate infrared thermal energy to make EPS insulation more efficient, helping users save on energy costs. We offer both carbon black and easy-to-disperse masterbatches to allow EPS producers to incorporate the carbon black into the EPS foam beads. When properly incorporated, our products deliver improved insulation performance while helping end users maintain other important quality parameters such as flame retardant performance and key mechanical properties.
Our award-winning aerogel particles are enabling the next generation innovations in energy efficient and healthy building products. As the industry leader in particulate aerogel additives, we are dedicated to bringing new innovations to the marketplace and helping our commercial partners and customers meet the growing demands for functional and energy efficient building solutions. Our aerogel product line delivers a range of benefits for building insulation applications, such as:
- Energy efficiency. Traditional insulating materials rely on trapping air or blowing agents within their structure to create insulation value. The performance of these materials is limited by the thermal properties of still air. Aerogel behaves differently due to its structure. This structure allows aerogel to achieve more than twice the insulating performance of still air. The open structure also allows vapor to readily diffuse through its matrix. Incorporating aerogel into existing or new insulation materials can displace air and replace it with the superior performance of aerogel. Aerogel additives enable insulation boards, blankets, plasters, coatings and composites to achieve previously unattainable thermal performance.
- Space savings. Our aerogel enables higher insulating values in less space than legacy insulation materials. Best-in-class aerogel-based building products, such as rigid boards, insulating plasters and thermal insulation coatings, can deliver up to three times greater thermal performance than peer products. When renovating with limited space, aerogel-based solutions can help achieve strict energy efficiency requirements. In new construction, architects gain superior flexibility when designing modern buildings.
- Moisture management. Building breathability has come to the forefront of the construction industry in recent years. As knowledge grows around building dynamics, there is a need for innovative products that help control gas and moisture transport and prevent mold and mildew. Other high performing insulation products on the market today are vapor-closed systems. Products made with our aerogel particles are typically breathable and do not promote the growth of mold and mildew. New vapor-open aerogel-based insulation materials and systems break the trade-off between high thermal performance and moisture management.
- Design flexibility. Aerogel additives provide product innovators the flexibility to achieve a broad spectrum of properties when creating new high-performance insulating products. Aerogel particles can easily be added and formulated into a variety of forms, such as slurries, dispersions, dry mixtures, coatings, plasters, non-wovens, textiles, composite boards, packs and more. Thermal insulation products incorporating our aerogel allow manufacturers to provide their customers with the highest performing insulation systems, allowing designers, architects and building owners to realize their aesthetic and energy efficiency goals.
Aerogel can be used in various building insulation applications, including:
Aerogel is used in boards for insulation and finishing systems. Aerogel containing boards deliver two to three times the performance of conventional insulation boards, requiring only one-third to one-half the space. This makes them an ideal option for interior applications where space is restricted and thickness of insulation especially critical. Aerogel-based rigid boards are hydrophobic and open to vapor, supporting the trends towards moisture management in building construction. To purchase aerogel-based rigid boards, please contact Sto.
In the past, historical preservationists and homeowners had to compromise between preserving the look of the facade and significantly improving the energy efficiency of historical buildings. Our aerogel products now deliver an insulating plaster solution that considerably reduces heating and cooling energy consumption while retaining the look of older buildings.
Plaster formulations using our aerogel provide better insulation than polystyrene board while still meeting the European fire class A specification. Aerogel-enhanced plasters have thermal conductivities of less than 30 mW/m-K (0.21 Btu-in/(hr-ft2-°F)) providing up to three times the insulating and thermal performance of standard insulating plasters. These benefits are achieved while maintaining the same application techniques and equipment used for traditional plasters.
Aerogel particles are used in granular form as insulating cavity wall infill. Aerogel particles flow easily allowing them to reach narrow spaces and flow around tight corners. Packed aerogel particles can have up to four times the thermal performance of other infill materials such as perlite, vermiculite and blown glass fibers. Aerogel-based building insulation can enhance your building's energy efficiency.
Solving Complex Challenges
Our passion for bringing new innovations to the marketplace is recognized with a prestigious global award.
Our aerogel was named the winner of Best Overall Innovation and Innovation with Best Environmental Benefit at the tenth annual Independent Chemical Information Services (ICIS) Innovation Awards thanks to its use in eco-friendly building and construction. The ICIS Innovation Awards recognize companies that have made significant steps forward in technological and business innovation.
The judging panel of leading industry experts selected our aerogel products because we leverage our passion for open innovation and extensive collaborations to bring a technology to market that is poised to have a dramatic impact on improving energy efficiency. Additionally, aerogel can reduce overall carbon footprints and energy costs in buildings around the world.
Advanced Insulating Plasters
Fixit 222, an aerogel-based insulating plaster product, won a Swiss environmental award for innovation.
The “Umweltpreis Schweiz,” also known as the Environmental Award-Switzerland in the innovation category, honored the Fixit 222 product that solved a complex technical challenge involving the renovation of historical buildings in Europe. Fixit AG partnered with the Swiss Federal Laboratories for Material Science and Technology, regionally known as EMPA, to develop Fixit 222, which provides more than two times the insulation capabilities of currently available insulating plasters.
Fixit 222 combines our highly insulating aerogel with hydraulic lime plaster to produce an insulating plaster for renovating historical buildings. The aerogel-containing material gives builders all the aesthetic and performance advantages of mineral plaster, along with a low thermal conductivity that is superior to expanded polystyrene (EPS) boards.
As a result, builders who use Fixit 222 are able to maintain the original external appearance that complies with historic preservation requirements, while making the buildings more energy efficient. Further, the combination of aerogel and lime creates a lightweight material that is non-flammable and allows for the elimination of environmentally hazardous flame retardants. The insulating plaster can be processed with conventional application machines for both indoor and outdoor areas.
