Profile system for concealed fixing of natural stone panels using pin bearings.

A sub-structure system based on NASTO-D is comprised of vertical T-shaped aluminium support profiles, wall brackets and optional accessories. According to their thermal loading and demands – the wall brackets are made of aluminium or stainless-steel.

The system consists of a vertical basic substructure, onto which the classic screw-in pin support is installed. Through the combination of the pin support with a substructure, the need to drill into the structure of the building is reduced and large loads can be realised in the Passivhaus standard with high thicknesses of insulation material.

The cladding elements are secured by means of pin bearings in the panel joints.

The support profiles are connected to the wall brackets using rivets or screws. When doing this, the sliding points take up horizontal (wind) loads and the fixed points take up the horizontal and vertical loads (dead load). Constraint free installation occurs at the sliding points in vertical longitudinal holes. One fixed point is allocated per support profile.

The wall bracket can optionally be fitted with installation aides, which make fixing and holding the support profile possible, and make it easier to work with them.

Thermostop Elements are available as thermal dividers to minimise thermal bridging.

Protrusions of up to 480 mm.
