Heimu Timber Perth WA

Heimu is a premium-quality, thermally modified timber renowned for its striking, deep chocolate-brown to nearly black hues and outstanding dimensional stability. The heat treatment process fundamentally transforms the wood’s cellular structure making it significantly less prone to moisture-related swelling, shrinking or warping. This stability ensures that Heimu remains durable and reliable in fluctuating environmental conditions.

Its enhanced surface integrity minimises checking and cracking, while also minimising tannin bleed, making it particularly suited for both interior joinery and exterior applications like decking, cladding, screening and outdoor furniture.

Natural Colour

When left untreated, Heimu ranges from warm dark brown to deep chocolate brown tones. Alternatively, when the timber is coated with penetrating oil, the timber will darken to almost black, offering a bold, luxurious appearance. The timber can fade to a more subtle brown/grey tone when exposed to UV.
