Imbue Joinery

Imbue™ Joinery combines refined natural timber aesthetics with modern thermal modification technology to deliver stable, durable, and versatile timber for internal and external joinery applications.

Imbue Joinery

Timber Innovation that Runs Deep

Imbue™ Joinery represents a breakthrough in timber performance, offering the warmth and beauty of natural wood with the stability and strength demanded in precision joinery work. Through advanced thermal modification, moisture and resins are driven out of the timber, producing a material that resists swelling, shrinking, and warping over time.

Ideal for doors, windows, frames, and detailed joinery elements, Imbue™ Joinery is engineered for versatility and long-term reliability. Its low thermal conductivity (lambda value 0.9) provides excellent energy efficiency, making it suitable for both interior fittings and exposed exterior components where stability is essential.

Supplied by Duce Architectural Timbers, Imbue™ Joinery offers consistent clear-grade quality, renewable sourcing, and compatibility with standard fixings and coatings. It’s a practical and sustainable solution that enhances performance without compromising on natural character.

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 Joinery

  • 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.
