• Double the hardness of western red cedar.
• Higher natural BAL rating than cedar or meranti.
• Excellent thermal and insulation properties superior to other materials like aluminium, steel or concrete.
• More durable than many other popular timbers in above ground applications.
• Natural material – renewable, energy efficient and will assist in reducing green-house emissions when swapping with high embodied energy materials.
• Quarter sawn stability for the most demanding applications.
• Sustainable regrowth resource.
• A single-glazed Glacial Oak window will outperform its non-timber competitors for Life Cycle Assessment (LCA) and insulation (U-Value).
• Being a medium density hardwood it is naturally BAL12.5 and BAL19 (Bushfire Attack Level) and a great thermal insulator.
• It is also more stable, straight and dent resistant than most timber windows, consistent in colour, and does not have knots.
• Strong nail and screw holding ability (great for security).
