Tight, efficient, reliable.
Thanks to our sealing compounds, adhesive tapes and sealing tapes, you can be sure of permanently sealed connections in ventilation systems – reliable, compliant with standards and versatile in use. Whether for air ducts, equipment connections or assembly joints: with our wide range of chemical-technical products, we offer the right solution for every application.
Sealing solutions for ventilation systems
In ventilation systems, reliable sealing is crucial – for energy efficiency, operational safety and the longevity of the entire system. With our extensive range of sealing compounds, adhesive tapes and sealing tapes, we offer you the right solutions for every application.
Our sealants are available in various designs and sizes and comply with national and international standards and guidelines. They are suitable for numerous applications in ventilation, air conditioning and building services engineering – from duct sealing to equipment integration.
A particular highlight is our wide range of sealing tapes, which enable quick, clean and permanently tight connections between air duct components. The range is complemented by high-performance adhesive tapes that meet the highest standards in installation and sealing.
All our chemical-technical products contribute to our central promise: Efficiency in energy. Because every tight connection is an active contribution to energy-efficient air ducts – and thus to sustainable, economical and future-proof systems.
Sealants for the highest demands
Our sealing compounds are the ideal solution for the safe and efficient sealing of ventilation components. They are characterised by a wide range of resistances and are therefore suitable for a wide variety of applications – from classic ventilation systems to demanding special solutions.
Whether high temperatures, aggressive media or strict hygiene requirements: we offer the right sealing compound for every challenge. Our products meet national and international standards and actively contribute to the energy efficiency and operational safety of your systems.
Sealing tapes for air ducts
Our duct sealing tapes – also known as underlay tapes – ensure permanently tight connections in rectangular air ducts. They are inserted crosswise between the components to be connected and guarantee airtight, energy-efficient installation in accordance with current norms and standards.
Thanks to their high resistance to moisture, temperature, ageing and mechanical stress, our sealing tapes are suitable for a wide range of applications – from classic ventilation ducts to demanding areas of application in industry and building services engineering.
Adhesive Tapes
Our cold shrink adhesive tapes offer a simple and effective way to seal or insulate air ducts – without the need for heat or complex tools. They adhere reliably to steel, galvanised sheet metal and many other materials, ensuring a secure, long-lasting connection.
Thanks to their discreet design, the tapes are ideal for visible installation where both function and appearance are equally important.
Sprays for professional use
Our repair sprays are versatile aids in production and maintenance. They enable quick and reliable treatment of damaged metal parts or cut edges and provide lasting protection against corrosion – clean, efficient and durable.
We also offer special leak detection sprays that allow you to quickly and visibly detect leaks in air lines – ideal for maintenance and quality assurance. The range is complemented by powerful cleaning sprays that effectively remove dirt, dust and deposits from machines and surfaces.
