KLC Generation 2 Horizontal Rusticated Timber Weatherboard System
Description

The KLC Generation 2 H3.2 range of Rusticated weatherboards, fascia, cavity battens, scriber and finishing boards (D4S) have been designed as a complete system. Used together they provide a complete H3.2 treated exterior cladding for residential and small commercial buildings.

KLC Generation 2 H3.2 products are manufactured from short lengths of clear high grade radiata pine that are finger-jointed together using a structural glue to produce an untreated length of 6.3metres (substrate). The substrate is then treated to H3.2, using the revolutionary wood treatment technology called MicroPro. 

  • Rustic Weatherboards: 135, 180, 215, 230mm x 18mm (Wellington and Hawkes Bay profiles also available)
  • Finishing Boards:
    • Scriber 65, 40mm x 18mm
