Rothoblaas DGZ is a double-threaded screw built to carry a roof insulation package straight through to the structure, so the insulation layer stays unbroken.

What it does

Two threads let one fastener connect the batten, the insulation and the supporting structure without interruption, avoiding thermal bridges. The cylindrical head sets out of sight in the batten. CE certified under ETA 11/0030 for hard, soft and facade insulation.

  • Continuous over-rafter roof insulation
  • Hard, soft and facade insulation boards
