Triboard — Construction Wall System

Triboard Construction Wall System is perfect for prefabricated housing, residential and commercial builds.

Triboard panel construction provides more useable space and smoother interior finishes for contemporary quality housing.

Triboard is a 3-layered panel with a wood strand core sandwiched between an MDF outer 'skin'. The result is a clean-lined panel that has high resilience and impact resistance and greater stiffness than other similar products.

Key Features
  • Uniform strength throughout Triboard's core gives it excellent load bearing capabilities
  • MDF surfaces gives a grade 5+ smooth finish capability for painting or overlaying
  • Resilient surface also delivers greater stiffness for the same weight when compared to other wood-based boards
  • Superior screw holding ability over other commonly used wall linings
  • Available in a variety of panel sizes, thicknesses and densities
Structural Timber
