Imbue Decking

Imbue™ Decking combines natural hardwood warmth with advanced thermal modification for a durable, stable, and sustainable outdoor solution.

Imbue Decking

Timber Innovation that Runs Deep

Imbue™ Decking brings together beauty and resilience through advanced heat treatment technology. The process stabilises the timber by reducing moisture and extractives, resulting in a surface that resists swelling, shrinking, and splitting.

With its warm brown tone and fine grain, Imbue™ Decking provides an elegant natural finish that can be maintained or left to weather into a soft silver-grey. The boards are smooth, splinter-resistant, and comfortable underfoot, making them ideal for residential decks, walkways, and commercial outdoor spaces.

Supported by Duce Architectural Timbers, Imbue™ Decking ensures long-term performance backed by a 15-Year Warranty and FSC® Certified sourcing, offering architects and builders a reliable, sustainable choice.

Initial heating process

Phase 1: Initial heating process
Kiln dried timber is placed in a thermal modification kiln and is gradually increased to a target temperature of 230 degrees. This process occurs over an extended period, with thicker boards requiring more time.
Phase 2: Peak temperature
Once the timber has reached 230 degrees core temperature, it is held for a minimum of 2 hours. At this point the thermal modification is occurring, and the temperature must be carefully controlled by probes. The moisture content of the wood at this stage is essentially zero.
Phase 3: Reconditioning process
After the timber has reached its peak temperature, it is slowly cooled, and reconditioned with steam. This raises the moisture content to a target of 7-8% moisture content.

Why Choose Imbue Decking

  • Proven Stability: About 50% less swelling and shrinkage than radiata pine, leading to cleaner lines and fewer callbacks.
  • Durability Verified: Durability Class 1 (EN 350-1) and Class 2 above ground (AS 5604), supported by 15+ years of testing.
  • Renewable Supply: FSC® certified plantation sources, supporting responsible specification and consistent availability.
  • Coating Friendly: Reduced resin, uniform substrate, and predictable absorption improve coating appearance and service life.
  • Thermal Performance: Indicative 20–30% better thermal properties than untreated radiata, contributing to building efficiency.

More Information

Imbue suits façades, decks, and joinery where low movement, reliable coating performance, and confirmed durability are critical. It is a practical solution for residential and commercial projects that require renewable materials with proven results.

Technical

Process: Heat tempering uses steam and high temperatures at or above 230°C, followed by controlled cooling and reconditioning to around 7% EMC. The process permanently changes the wood’s chemistry to reduce hygroscopic behaviour and improve resistance to decay.

Indicative Technicals: Average dry density ~420 kg/m³, pH ~3.9, Janka hardness ~2.5 kN, MoE ~8 GPa, MoR ~50 MPa. Thermal conductivity ~0.095 W/mK, approximately R1.35 per 25 mm thickness. Use stainless steel fixings externally, separate from zinc if required due to acidity.

Workability: Excellent machinability with sharp tools, pre-drill for fixings, manage fine dust extraction. Smooth dressed timber should be sanded before coating, always confirm systems with coating suppliers.

Fire: D-s1-d0 (EN 13501-1), Class C (ASTM E84), Group 3 (AS/NZS 3837), subject to project-specific compliance and installation details.
