South East Asian tropical hardwood popular in NZ for Decking

A JSC Timber solid hardwood deck made from renewable natural resources is not only an architectural link between the landscape and the built environment; it adds value to your home and uses one of the world's truly renewable resources.

Kwila heartwood is yellow-brown to dark red-brown in colour. The grain is slightly interlocked, and the texture is moderately coarse. Yellow deposits in the vessels are a common feature of the wood. It is nonsiliceous, sometimes lustrous—timber ‘bleeds’ when wet producing dark red-brown stain.  

JSC Timber has an extensive range of standard and custom profiles along with many colour options that will ensure your Kwila project not only looks great but stands the test of time. Please scroll through the gallery above to be inspired and contact us today for your personalised quote.
