Trapezoidal profiles are often used as supporting static substructures for build-ups on warm and cold roofs. For this reason, Zambelli has developed the innovative Thermo-Z spacer profile for substructures,. Its several rows of slotted holes, which are arranged in a staggered manner, allow for a reduced thermal bridge effect and better U-values. Thermal separating strips, commonly used between the roof cladding and the supporting structure, are no longer necessary. The Thermo-Z spacer profile provides an alternative to classic wood.

It is impossible to build or renovate a warm roof today if you do not comply with the energy efficiency standards. During the planning stage, it is important to strike a balance between the legally required U-values and roof construction costs.

RIB-ROOF metal roof systems offer a wide variety of build-ups for warm and cold roofs. Trapezoidal profiles are often used as a supporting static substructure in the industrial construction due to their excellent cost-efficiency. Forschungsinstitut für Wärmeschutz e.V. Munich (FiW) has confirmed that outstanding U-values can be achieved with the newly developed Thermo-Z spacer profiles. Thus, we recommend using the innovative Thermo-Z spacer profile to combine economc efficiency and sustainability in the simplest way.

Roof build-ups with Thermo-Z spacer profiles can be used for both truss and purlin roofs. Depending on the requirements, the Thermo-Z spacer profiles are laid in a single layer at 90° or 45° to the trapezoidal sheet metal rafters. They are mainly used for warm roofs, but cold roofs with a free ventilation cross-section can also be executed.

In warm roof constructions, the Thermo-Z spacer profile can be used on supporting shell constructions (e.g. trapezoidal sheet metal or wooden sheathing) to reduce thermal bridges. The Thermo-Z spacer profile can also be installed as a spacer construction for ventilated roof structures with a free ventilation cross-section.
