Beautiful Batu Siding

Batu hardwood siding is a beautiful, naturally durable and competitively priced product. This article discusses various options for hardwood siding in Batu, aka Red Balau or Mahogany.

Choosing a Batu Hardwood Siding Pattern

There are a large number of options for hardwood siding in Batu. All of the standard WRCLA patterns, typically used for Western Red Cedar or California Redwood, are available. The most popular patterns are T&G with an edge V (either 1/4" or 1/8"), shiplap with a 1/4" fine line reveal, bevel siding with one re-sawn face, and pattern 105/106 which uses a soft radius on one edge and a hard 90 degree edge on the other side of the reveal. Samples of patterns can be provided by the leading suppliers of Batu hardwood siding.

In addition, for the custom home application, just about any pattern you can imagine can be run in the Portland, Oregon area. We are lucky in this part of the world that so many high quality remanufacturing options exist. The Portland area is home to Diebold Lumber, Trillium Lumber and Trillium Pacific. Typical set charges for custom knives run around $300 plus molding charges on a per lineal foot basis.

Installation Requirements

The most critical aspect of installation of hardwood siding is to be sure the hardwood can breathe. There must be an air gap behind the siding so that moisture can quickly evaporate and will not accumulate behind the hardwood siding boards. The key requirement is the air gap which can be achieved with any of the popular rain screen systems such as Climate Shield. In many cases, installers can achieve the necessary air gap behind the boards simply by running furring strips perpendicular to the direction of the siding.

There are certainly other critical elements of a successful installation including finishing and fastening. Finishing should be done with a high quality oil based finish, we highly recommend using ExoShield. Fastening is always best done by pre-drilling and the applying screws right through the face or with a stainless steel nail / fastener applied underneath the adjacent piece.


Yes, hardwood siding does need to be maintained, especially if finished with any of the transparent or semi-transparent oil finishes are used. How often will depend on the climate and which finish was used. We've heard of everything from once a year to once every five years. Hardwood siding with an oil finish does require more maintenance than paint - but, it is also ridiculously good looking.
