Bangkirai – Yellow Balau

Benefits of Bangkirai Yellow Balau decking

• Bangkirai Yellow Balau are sought after for their immense durability.
• It is generally considered reliable and hard.
• You can choose from two appearance variants.
• It is highly resistant to water.
• We supply with profile Reeded/Grooves because it is designed to allow for airflow underneath the boards to stop moisture and mould build-up.
• We supply with Standard&better grade.

Origin
Bangkirai Yellow Balau is a wood originating from Asian countries such as Burma, Thailand, Laos, Vietnam, Cambodia, Malaysia, the Philippines and Indonesia.

Description
Yellow Balau is tropical timber regularly used for exterior decking. The timber is a yellowish – reddish-brown colour and classifies from durable to very durable. The bangirai wood is used for freshwater construction, so it is suitable for the decking on boats.
The interlocked grain makes machining Bangkirai Decking difficult. Bangkirai has a natural hardness which has a blunting effect on tools. So that’s why buying ready machined Yellow Balau decking can be beneficial.
The timber tends to be readily available, making it more favourable cost wise compared to other tropical timbers.

Recommendation
We recommend treating Bangkirai wood terraces with wax on all cutting sides before installation - Osmo Wax for cutting edges No. 5735. If you decide to finish the Bangkirai decking, then it is possible after approx. Three months after exposing the terrace to direct weathering.

If you choose not to finish the deck’s surface, a grey patina will be created. Greying occurs due to sunlight and water. The essential component of radiation that affects the greying of wood is UV radiation. Wood molecules absorb this radiation. Due to radiation and water, grey patina forms on the surface and into the wood’s depths. This grey patina will eventually become natural protection against further exposure to UV radiation.

How Bangkirai wood behaves
Wood is a hygroscopic material, and for this reason, it changes its shape depending on air humidity. Depending on air humidity and ambient temperature, this humidity change process is reversible but does not occur on the same plane. For the same relative humidity and air temperature, the wood’s moisture is higher during desorption than during absorption, with a range of relative humidity RH 30% - 90% by 2.5% to 3.5%. It means that the wood reduces its volume during drying and does not return to its original dimension when moisture is taken back. This fact has a fundamental influence on the behaviour of the Bangkirai terrace in Kiln dry state.

Recommended dilatations
There are changes in humidity and long-term rain, snow, melting snow ..), and boards will increase their sizes in this period, but by 2.5 - 3.5% of their current width. Furthermore, it should be noted that the terrace panels are cut in different orientations to the trunk axis, tangentially, radially but also semi-radially, which affects the drying in dimensional percentages. Therefore there are always different dimensions in the gaps between the boards laid with the same dilatation

We recommend dilatations gaps between 5 - 8 mm.
