Compatible accessories for a complete and safe installation

The 15-degree support is one of Hormicad’s most versatile, and it can be complemented with a selection of accessories designed to make installation easier, reinforce the structure, and ensure a professional result on all types of flat roofs.

  • Hardware extension system: very useful for vertical installations, it allows you to adjust the fixing of large panels without compromising the manufacturer’s warranty.

  • Anti-buckling system: improves module rigidity against wind, especially in horizontally oriented installations.

  • Levelling system: essential on roofs with slope or unevenness, it allows you to correct the height of each support to align all panels.

  • Grounding plate: integrates into the hardware and ensures equipotential bonding without bridges or additional drilling.

  • Rubber mat: protects the roof from abrasion and improves grip on surfaces such as sandwich panels or bituminous membrane.

  • Polyurethane adhesive: allows the support and ballast to be firmly fixed without the need for mechanical anchors.

  • New 1-metre ballast with grooves (coming soon): designed specifically for the 15° support, it makes transport and placement easier thanks to its side handles.
