Fraké Noir is the brand name for a thermally modified hardwood called Limba. A natural heat treatment process that uses only heat and steam (no chemical additives) significantly improves this non-durable timber species' performance.
Thermally modified Fraké Noir meets Durability Class 1, designating it 'very durable' with a service life of 25+ years according to NEN-EN 350-2. The thermal modification process also makes the wood extremely stable and gives it a characteristic walnut/chocolate brown colour, with a warm, luxurious appearance.
This Channel 10 profile is part of the Optima Series, a range of precision machined profiles that feature unique design details that make them easier to install and to help them perform better. Cladding profiles in the Optima series feature a discreet nail line for ease of installation together with a substantial overlap where the boards connect to accommodate the natural movement in wood.
The Optima Channel 10 pro?le can be installed either horizontally or vertically. A square-sided recess where the boards meet creates bold shadow lines that will accentuate either the height or width of the façade. Boards connect with a tongue and groove system for easy installation.
- Sizes: 18 x 140mm
- Grade: Typically knot-free on the face. Mostly free of defects. Some pinhole present. Can exhibit variable grain giving some movement along the length.
- Profile: Optima Channel 10 has a tongue and groove connection and provides deep, bold shadow lines created by the recess.
- Installation: Horizontal or vertical.
- Surface texture: Smooth.
- Colour: A rich walnut/chocolate brown colour consistent throughout the section of the piece.
- Durability: Fraké Noir has a decay resistance of durability class 1 (very durable) according to the EN 113 standard. A service life of 25+ years can be achieved, or 60+ years if a surface coating is applied at the outset and maintained periodically.
- Stability: The lower equilibrium moisture content and the changes in the chemical composition of the wood during the heat treatment process make Fraké Noir less able to absorb and release water, thereby improving dimensional stability. Tangential shrinkage ≤ 2%.
- Density: The density of Fraké Noir is 540kg/m³.
- Thermal properties: The thermo-modification process greatly improves the insulation value.
- Grading: Fraké Noir is generally well presented. The material is mostly free of defects on the face, with some small crumbly knots on the reverse. It has a uniform colour with some black mineral staining/streaks if inspected at close quarters.
- Sourcing/certification: Limba is a so-called lesser-known timber species (LKTS) from Central Africa. FSC is promoting the use of LKTS from FSC certified forests to make forestry more sustainable in the long term. There is an abundant supply of raw material with Limba not listed in CITES (Convention on International Trade in Endangered Species).
- Limba used in Fraké Noir's production is sourced from FSC 100% origin with a reduced impact on logging areas, thereby giving the forest an enduring economic value to ensure it remains preserved and valued as a resource for local employment opportunities. One tree per hectare is logged on a 25-year cycle.
- Fraké Noir from Silva Timber is supplied with full FSC chain-of-custody certification.
