The SPIRO® System

The SPIRO®-system includes several advanced features designed to streamline the installation process and enhance efficiency, resulting in a high-quality final product.

Benefits of the SPIRO® System

The SPIRO® system uses a sealing strip made from age-resistant EPDM rubber to create an airtight joint seal that remains stable despite changes in temperature.

It meets air tightness standards at Class D, with components available in diameters ranging from 100 mm to 2500 mm.

Factory-mounted sealing strips enable installation without the need for extra sealing, as each application is fully sealed upon setup.

Spirally wound tubes produced by our ‘tubeformers’ incorporate a patented seam cavity designed to stabilise the tubes and secure the seams, maintaining tolerances during handling and transport.
