Yellow Balau decking: Durable elegance for your outdoor spaces

When it comes to choosing decking material for your terrace, the options are plentiful. However, if you’re looking for a blend of durability, aesthetics, and value, yellow balau decking emerges as a standout choice. This tropical hardwood, originating from Southeast Asia, is increasingly popular among homeowners and construction professionals alike. Let’s delve into the characteristics, benefits, and maintenance tips for yellow balau decking, offering you insights to make an informed decision for your next outdoor project.

Characteristics of Yellow Balau

Yellow balau, known scientifically as Shorea laevis, is a dense, hard timber with a natural resistance to weather, rot, and insect infestations. Its colour palette ranges from a warm yellow to a deep brown, developing a silver-grey patina over time if left untreated. This wood’s tight grain and natural oils contribute to its durability, making it an excellent choice for decking that withstands the elements.

  • Bangkirai is used in freshwater construction, making it suitable for boat decking.
  • The interlocked grain makes Bangkirai hard to work. Bangkirai has a natural hardness that blunts the effect of tools. That’s why buying finished Yellow Balau can be advantageous.
  • The wood is readily available, making it more cost-effective than other tropical woods.

Maintenance Tips for Bangkirai Yellow Balau Decking

To ensure your bangkirai yellow balau decking continues to look its best and lasts for years, follow these simple maintenance tips:

  • Regular Cleaning: Sweep the deck regularly to remove debris and wash it with mild, soapy water and a soft brush a couple of times a year to prevent mould and mildew build-up.
  • Oil Treatments: We recommend that Bangkirai decking be waxed on all edges before installation - Osmo Wax for Cutting Edges No. 5735. If you decide to finish your Bangkirai deck, you can do so after approximately three months of direct exposure to the elements.
  • If you choose not to finish the deck surface, a grey patina will develop. Greying is caused by sunlight and water. The main component of radiation that causes wood to turn grey is UV radiation. The wood molecules absorb this radiation. Radiation and water create a grey patina on the surface and in the depths of the wood. This grey patina eventually becomes a natural protection against further exposure to UV radiation.
  • Avoid Painting or Staining: To preserve the natural beauty and characteristics of yellow balau, avoid painting or staining the wood. Instead, opt for oil treatments that enhance its natural hues.
  • Prompt Repair: Address any signs of damage or wear promptly to prevent further deterioration. Replace damaged boards and secure loose ones as needed.

Bangkirai Yellow Balau’s behaviour over time

Wood is a hygroscopic material, which means that its shape changes depending on the humidity. Depending on the humidity and the ambient temperature, this process of moisture change is reversible but does not occur in the same plane. For the same relative humidity and air temperature, the wood moisture during desorption is higher than during absorption, with a range of relative humidity RH 30% - 90% by 2.5% to 3.5%. This means the wood loses volume during drying and does not return to its original dimensions when the moisture is removed. This fact fundamentally influences the behaviour of the Bangkirai terrace in the kiln-dried state.

Recommended dilatations

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