Advantages

  • Exceptional processing properties and long-term protection of thermal insulation and roof structure
    DELTA®-REFLEX has an Sd value of approx. 150 m and, thanks to its lattice reinforcement, a high tear strength of up to 450/400 N/5 cm. Thanks to the high tensile strength and “boardiness” of the track, it is easy to use and perfectly suitable for the construction site.
  •  Heat reflection
    The product DELTA®-REFLEX provides a optimised heat protection by means of heat reflection (tested by the Institute Fraunhofer Institut in Freiburg, Germany). Saving energy and money!
  • Air and vapour
    Stop connection with the system accessories DELTA®-MULTI BAND, DELTA®-TIXX, DELTA®-LIQUIXX, DELTA®-KOM-BANDDELTA®-REFLEX also offers a safe air and vapour stop for all overlapping elements and connections. As a consequence, no heat energy gets lost through uncontrolled air flow.
  • Structural fire protection for flat roofs
    The product DELTA®-REFLEX offers certified security for large flat roofs in industrial buildings. The requirements of the standard DIN 18234-1 are met. The track width of 3 m is also ideal for use in lightweight industrial roofs - whether on aerated concrete or trapezoidal sheet metal substructures.

Application

Thanks to its layer structure and its material composition the product DELTA®-REFLEX is tear-resistant and therefore easy to use.
The above-average tear strength (of approx. 450/400 N/5 cm) prevents tearing and further tearing in the course of the installation. The stable material enables rapid and clean work, even on difficult details.
