Timber battens

Economical and durable, timber battens are widely used for all applications from fascias and soffits to total cladding.

An economical method of application for Marley Eternit cladding panels is that of mounting on a timber framework using rainscreen construction principles.

Unless specific fire performance requirements or irregularities to the substrate are encountered (where other adjustable Marley Eternit Systems are employed), timber battens will provide an economical and speedy installation.

Timber protection
Timber battens can be protected against decay and insect attack in accordance with BS 5268:Part 5


Ventispan

The Ventispan system provides a framework for the cladding of both concrete and steel framed structures.

Designed to be anchored to the structure at each floor level.

A highly adjustable system allowing for irregularities in substrate surface, Ventispan is ideal where poor quality infill material on existing buildings dictates that fixings can only be secured at floor slab positions.

Please note: rivet fixing of Eter-Color is to be by the Astro Rivet System.

Mechanical Secret Fix

This secret fix system is suitable for use with 12mm thick Natura, Textura and Pictura panels and supports the cladding panels by means of aluminium profiles.

The fixing method chosen can have a fundamental and dramatic effect upon the final appearance of the clad building. Employing a secret fix method will result in a sheer smooth façade unobstructed by fixings.
Omega & Zeds

A simple metal component system easily installed in a similar fashion to timber battens with the added benefit of non-combustibility and a completely rof-proof construction.

As an alternative to timber battens, particularly where there is a specific requirement for non-combustible frameworks, a lightweight aluminium framework can be used.


These can be fixed either directly on to a concrete, brick or block wall, or to a purpose-designed rail system. Marley Eternit’s cladding panels, Natura, Textura and Pictura can then be rivet-fixed to the Omega and Zed.


Please note: rivet fixing of Eter-Color is to be by the Astro Rivet System.

Structural Bonding

The Marley Eternit structural bonding system utilises structural adhesives to fix internal and external cladding panels for a secret fix system.

The Marley Eternit structural bonding system utilises structural adhesives to fix internal and external cladding panels for a secret fix system.
Ventisol

A highly engineered system of top quality components specially developed for fixing to new or existing structures.

The adjustment within the components allows a true plane to be easily achieved for the new cladding facade.

An aluminium frame fixing system able to provide adjustable void depths to accommodate insulation, and able to overcome irregularities in the supporting substrate.

Please note: rivet fixing of Eter-Color is to be by the Astro Rivet System.
