What is unrestrained fastening, and why is it necessary?
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.
What features does the EJOT® LT system offer for facade fastening?
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, a 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 bush for the visible fastening of cladding panels.
How do centring bushes contribute to durability and visual finish?
The centring bush fulfils important tasks in the system and is 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.
