Understanding Decking Materials

Different wood species carry distinct cellular traits, grain patterns, and density ratings. Whether you choose the rugged rustic charm of Siberian Larch or the architectural luxury of premium hardwood, understanding your material's raw characteristics is key to a successful installation.

[01]

Siberian Larch

Highly resinous, slow-grown dense conifer that resists rot and decay naturally.

[02]

Red Cedar

Incredible dimensional stability with rich warm reddish-brown hues and unique aroma.

[03]

Premium Oak

Traditional English aesthetic. Hard, durable, and ages to a striking silver-grey.

[04]

Treated Redwood

Pressure-treated pine that represents the peak utility-to-value choice.
