Unrestrained fastening

Guide for rear-ventilated facades – Part 7

In the previous parts, our guidebook on rear-ventilated facades has provided basic information as well as the basics of anchoring and the mounting elements to be used. The selection of the right material for the substructure and the formation of fixed and sliding points were also discussed. This last part deals with the unrestrained fastening of cladding panels.

The necessity of an unrestrained fastening is not only specified by design guidelines, approvals and assembly guidelines, but is important for the later appearance of the facade. Even minimal thermal length changes in the system can suffice to cause plates to buckle and to create bumps in the facade. In order to obtain a planar and visually appealing facade surface, it is imperative to ensure an unrestrained fastening with a combination of fixed and sliding points.
 

EJOT® LT system

The EJOT LT system offers a wide range of products for professional and visually flawless fastening of facade cladding. The range of products includes a wide variety of screws of various designs for various types of plates and substrates, centring bush for a uniform design of fixed and sliding points, and special setting tools for fast and secure assembly. The screws of the LT system are used together with the fixed and sliding point bushs for the visible fastening of cladding panels.

The centring bushs fulfil important tasks in the system and are an elementary component in addition to the screws. They centre the screw in the centre of the drill hole in order to allow movements in all directions during subsequent length changes of the plate. The collar on the sleeve protects the plate surface during the movements from scratching by the screw head. In order to make the visible fastening visually appealing and as discreet as possible, EJOT offers an individual, coloured lacquering of the screw head – there is a creative solution to nearly every situation.
