Timber Decking
A well-designed timber deck can transform outdoor spaces, but it’s essential to choose the right materials and installation methods to ensure durability. Decking timber is exposed to harsh weather conditions, including direct sun, rain, and humidity, making material selection, set-out, fixing, and treatment more critical than in other timber applications.

Timber decking is available in a variety of sizes: • 86 x 19mm • 135 x 19mm • 130 x 25mm • 135 x 32mm A general rule of thumb suggests that exposed decking should maintain a width- to-thickness ratio of no more than 5:1. The 86 x 19mm size has been shown to be less prone to cupping, while thicker boards (25mm or 32mm) help reduce flex and warping over time.Screening Battens & Specialty Options
