Hardwood Cumaru Decking Products
Exceptional Density and Exterior Performance
Vista Timber offers premium Cumaru 1×6 decking, also known as Brazilian Teak, recognized as one of the most durable hardwoods for exterior applications. With its extremely dense structure and natural resistance to moisture, mildew, decay, and insects, Cumaru is an ideal solution for demanding outdoor environments and high-performance architectural projects.
Rich Natural Appearance
Cumaru features deep reddish-brown tones with a tight and elegant grain pattern, creating a warm and sophisticated natural aesthetic. Over time, untreated surfaces gradually weather into a refined silver-gray patina while preserving the hardwood’s structural integrity and visual appeal.
Ideal for Outdoor Applications
Cumaru decking is widely used for terraces, walkways, landscaping projects, commercial outdoor spaces, and seaside applications. Its stable surface resists scratching and splintering, remains comfortable under direct sunlight, and provides excellent slip resistance for safe exterior use.
Long Lifespan and Structural Stability
Cumaru is engineered by nature to withstand demanding outdoor conditions, including moisture, temperature fluctuations, and heavy pedestrian traffic. Its exceptional hardness and structural performance make it suitable for long-term residential and commercial exterior projects.
Installation and Workability
Due to its high density and natural oil content, Cumaru decking should be pre-drilled and installed using screws and professional fastening systems. This ensures long-lasting structural performance and stability in exterior environments.
Low Maintenance
Cumaru requires minimal maintenance compared to many exterior decking materials. Periodic oiling can help maintain its original rich tones, while untreated surfaces naturally develop an elegant weathered appearance over time.
Sustainably Sourced Hardwood Solutions
Vista Timber supplies responsibly sourced Cumaru hardwood products suitable for architects, contractors, and premium outdoor construction projects. Sustainably harvested hardwood options support environmentally conscious and long-lasting exterior applications.
