For the right temperature.

All common build-ups for warm and cold roofs can be fitted as roof build-ups for the RIB-ROOF metal roof system.

Supporting or substructures

The supporting or substructure  for the RIB-ROOF profile sheets can be designed as follows:

  • Single-shell roof construction with thermal insulation layer, aka a warm roof
  • Single-shell roof construction without thermal insulation layer
  • Double-skin roof construction with rear ventilation, aka a cold roof


All common build-ups are essentially possible for roof build-ups with RIB-ROOF:

  • Trapezoid profiles
  • Wooden purlins
  • Wooden formwork
  • Steel purlins
  • Aerated or reinforced concrete


Steel trapezoidal profiles are among the most common supporting structures. RIB-ROOF Speed 500 can be mounted alternatively on a full-surface support. Compression-resistant and walkable thermal insulation is another variant, besides the wooden formwork (used in DAD-dm compressive pressure load capacity).





Possible build-ups for warm roofs.

  • Wooden counter/cross battens
  • Wooden formwork
  • Roof build-ups with clip strip
  • Thermo-Z spacer profile
  • Z-profile
Energy cost savings with wooden battens.

The FIW study report of 17/01/2020 (calculation with DIN EN ISO 6946, values in each case for 180 mm of thermal insulation and WLG 035) indicates annual savings of approx. €1,400 per 1,000 m² of roof area by fitting a spacer made of wooden slats compared to constructions with a metallic Z-profile without a thermal separation strip. Compared to metal supports that penetrate the thermal insulation, annual savings on energy costs are around €540 for the same area.

Possible build-ups for cold roofs.
