Timber Decking & Screening

Timber decking is available in sizes 86 x 19mm, 135 x 19mm, 130 x 25mm and 135 x 32mm. There is an old rule of thumb that insists exposed decking stay within 5:1 ratio of width vs thickness - and reliably, 86 x 19mm has proven less likely to cup on the upper face than wider decks. Increased thickness of 25mm or 32mm is another type of insurance to minimize cupping or flex in surface dimension. Timberzoo screening battens in Blackbutt, Ironbark and other durable species are great for walls, windows, deck perimeters, picket fences and other landscape projects.

Timber Decking & Screening

Decking is one of the most testing installations for hardwoods in the broad construction repertoire. A new deck is a project that should be researched well before commencing. Decks are exposed to rain and baking sun on one face with a shaded - and often humid - underside. It is vital that design, choice of materials, set-out, fixing and treatment of decking timber be considered as more important than in other timber applications. There are many guidelines and sources of advice for building a deck and listed below are several we recommend:

Durability Class 1 species - DC1

Durability Class 2 species - DC2

Ironbark Darwin Stringybark Forest Red Gum Spotted Gum (with preservative-treatment) sapwood

Blackbutt Silvertop Ash Jarrah
