TefaFix® F facade substructure for a durable wooden facade

With TefaFix® F for the facade, SIHGA® has developed a substructure rail made of aluminium that can be used for both visible and invisible facade fixing. The material is durable and can be worked with conventional tools and machines - which simplifies the fixing process. The substructure for the facade is available in bare aluminium and SC 9 coating. The coated version creates a black joint look throughout.
A spacer can be inserted into the slot provided in the rail - effortlessly and without time-consuming fixing. The given spacing of the profile thus ensures optimal ventilation and drainage.

Facade substructure with TefaFlex® F for a permanently beautiful appearance

TefaFlex® for visible facade fixing can be combined very effectively with the system for the facade substructure. The product can simply be inserted into the shaft provided in the TefaFix® F - no time-consuming fixing is needed. With a length of 40 mm, the system can be used for all profile widths and the height of 8.5 mm ensures a fixed distance between the profile and the substructure.
SIHGA® recommends the TefaFlex® F for the vertical installation of facade boards. The system's special geometry ensures optimum rear ventilation of the facade and allows water to drain away perfectly to prevent waterlogging and moisture build-up. This ensures a permanently attractive appearance of the facade.

Frequently asked questions about facade substructures:

SIHGA® has several systems for facade substructures in its range. The innovative TefaFix® F system is a universal and flexible fixing option. The aluminium product provides a secure hold and, thanks to sufficient ventilation and drainage, ensures a permanently beautiful appearance of the facade cladding.

The substructure contributes significantly to the stability and durability of the facade, as it carries the entire load. For this reason, choosing the right fixing method and material is a very important decision. SIHGA® therefore relies on aluminium in its systems - it provides a secure hold and is versatile.

A rear-ventilated facade with an appropriate substructure protects the insulation from the weather and ensures sufficient drainage - so the insulation remains dry and permanently functional. The facade and the insulation are thus clearly separated and damage due to moisture, weathering, rot, fungus and algae infestation can be avoided.
