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
