Strongfix System

Mixed hidden longitudinal fastening system

The Strongfix system is a mixed hidden longitudinal fastening system (chemical and mechanical), which works by the compression exerted by the system on the back of the Neolith tile.


These tiles are industrially mechanized in a longitudinal profile at the top and bottom of its backside with a double 45º groove in the shape of a dovetail where a couple of aluminum profiles are inserted and fixed with a MS adhesive putty in order to secure the Neolith tile. These metal profiles make up the hanging mechanism of the tiles and result very beneficial given that they are very easy to extract and replace.


The system is composed by aluminum vertical profiles, supporting retaining brackets.


Through the brackets it’s possible to install the aluminum “T” profiles totally flatness, thus correcting possible wall deviations of the facade to be coated.


The panels are hand set to a horizontal supporting profile with a mechanical longitudinal fixation system composed by two aluminum profiles fixation.


This aluminum set becomes indivisible given the mechanizing method of the tile and the fixing of the profiles. This system eliminates the risk of Neolith slabs becoming detached from the structure in case of breakage. This is the reason why this system is considered the safest in the market.

Furthermore, the way in which the Neolith slabs are hung on the horizontal structure provides for perfect flatness and aesthetic finish.


The Strongfix system also allows for easy extraction and replacement when needed.

Strongfix System Installation Steps



Façade staking: aluminum vertical profiles arrangement and staking, which can be installed completely independent to the vertical joints.


Vertical profiles installation: the vertical structure is anchored to the wall using retenciton and supporting brackets and anchors.






Horizontal profiles installation: it is needed to be determined the horizontal profiles position, in response to horizontal cutting façade scheme. This structure is anchored to the vertical structure by 5,5 x 19 cm drilling screws.



Neolith cladding installation: it is needed to start by the bottom of the façade. It is a façade system very fast to install which allows to replace the slim tiles if it is required.

NEOLITH’s Strongfix System Receives ICC Certification

Neolith, has received certification from ICC Evaluation Service LLC (ICC-ES) that its patented StrongFix System for ventilated façades complies with the provisions of the 2018, 2015, 2012 and 2009 International Building Codes® (IBC) and International Residential Codes® (IRC).


The recognition represents a significant validation of Neolith as a safe, robust, sustainable and easy to specify solution for exterior cladding applications in North America.


To achieve certification from ICC-ES, Neolith’s surfaces had to undergo a number of structural regulatory tests. These measured important characteristics such as non-combustibility, wind and water resistance, fastening integrity and resistance performance of the StrongFix system.


Over the last decade, Neolith has become an increasingly popular choice for ventilated façade projects due to its low maintenance, anti-reactivity, inherent strength and relative light weight when compared to other cladding systems.
