SmartClad™ Bevelback Weatherboard Cavity Cladding System

Description

The SmartClad™ Bevelback Weatherboard Cavity Cladding System is a cavity-based external wall cladding system for residential and light commercial type buildings where domestic construction techniques are used. The system utilises the SmartClip™ fixing clip to aid speed of installation.
