Korina is a medium density West African tropical hardwood. Korina, also known as Frake, is a secondary species not typically used for exterior applications as it does not meet the durability requirements.
The thermal modification process does lower the strength and density, as it does with any species.
However, as the starting density and weight of the species are sufficient, the end result of thermal modification is a product that is still well suited for decking and railings as well as siding and soffits.
Korina should not be used for heavy industrial applications or heavy weight bearing structures.
In those cases we suggest Rhino wood which is significantly harder and heavier due to its dual modification process.
Korina experiences several benefits from the thermal modification process:
The color, which is light and not specifically appealing, turns a pleasant brown while retaining the natural variations in the wood, making for a very appealing product for your home.
Also, the stabilityand the durability is significantly increased, making the species well suited for many exterior and interior uses.
Thermally modified Korina is much less likely to shrink and expand or warp in the weather, and as durable as Batu or Bangkirai for external use.
We make the same recommendations for decking and siding installation as we do for our regular tropical hardwood products.
Korina is always sourced from sustainably managed forests as a secondary species, and will be fully OLB, Origine et Légalité des Bois, certified.
FSC, Forest Stewardship Council, certification may be available for larger projects when required.
