Cumaru RainScreen Siding

Description

Built for Bold Character and Long-Term Exterior Performance

The Cumaru RainScreen Siding profile delivers premium exterior hardwood cladding with rich natural color variation and real tropical hardwood performance. Milled from durable Cumaru hardwood, this product is shaped for a hidden-fastened rain-screen siding system. Its profile creates clean shadow lines, modern architectural depth, and a ventilated wall assembly designed to help moisture drain and dry naturally. Known for its impressive density, rot resistance, insect resistance, and bold red-and-gold appearance, Cumaru RainScreen Siding delivers a warm natural hardwood façade that outperforms painted wood, softwood siding, and synthetic cladding in both beauty and long-term durability.

Premium Grade A Cumaru from Brazilian Wood Depot

Brazilian Wood Depot provides only Premium Grade A (FAS) Cumaru hardwood, ensuring every board meets strict standards for appearance, profile quality, and structural use. Cumaru is often called Brazilian Teak and is known for its golden honey, amber-brown, reddish-brown, and deep red tones. This board-to-board variation is part of its natural character, creating a bold exterior look with movement, contrast, and warmth. Because this product is milled specifically for rain-screen siding, it is ideal for projects that require a clean hidden-fastener surface, strong architectural presence, and long-term exterior performance.

Designed for a True Ventilated RainScreen System

Cumaru RainScreen Siding is designed to be installed over furring strips, creating a continuous air cavity behind the boards. This ventilation gap helps incidental moisture drain and dry instead of becoming trapped behind the siding. That matters because Cumaru is dense and durable, but it still rewards careful detailing, proper fastening, and good airflow. For full installation details, review our Rain Screen Certified Installation Guide and watch the Rain-Screen Siding Installation Video.

Rich Color Variation and Natural Protection

Cumaru’s red and gold color range makes it one of the most visually dramatic hardwoods for exterior siding and modern cladding. Its dense fiber structure and natural oils help resist decay, insects, and weather exposure without chemical treatment. Unlike more uniform hardwood species, Cumaru creates a lively façade with natural board-to-board contrast. When properly installed as a ventilated rain-screen system, Cumaru siding can deliver long-term exterior performance while maintaining the warmth and authenticity that composite and plastic cladding cannot replicate.

Clean Hidden-Fastener Appearance

Unlike face-fastened siding, Cumaru RainScreen Siding is milled for a hidden clip system that keeps the visible surface clean and uninterrupted. The result is a high-end architectural look with no exposed screw heads, crisp horizontal or vertical lines, and attractive shadow reveals between boards. This makes it an excellent choice for feature walls, modern façades, luxury homes, commercial entries, outdoor living spaces, and accent cladding.

RainScreen Siding vs. Tongue & Groove Cladding

Rain-screen siding is best for fully exposed exterior walls because it allows airflow behind the boards. Tongue-and-groove cladding is better suited for protected areas like soffits, ceilings, covered porches, and walls with limited rain exposure. If your project is exposed to direct rain, sun, and changing weather, the ventilated rain-screen system is usually the better long-term choice. For protected ceilings and soffits, explore our Tongue & Groove Cladding and Ceiling resource.

Weathering, Oiling, and Long-Term Appearance

Like all natural exterior hardwoods, Cumaru siding will gradually weather to a silver-gray patina when left unfinished in sunlight. This color change is cosmetic and does not mean the wood is failing. Because Cumaru starts with strong red and gold tones, the weathering change can look more dramatic than it does with darker brown species. Customers who prefer to preserve the original warm tones can periodically clean and oil the siding with a UV-protective hardwood oil. For exact cleaning and oiling guidance, use our Messmer’s Certified Cleaning & Oiling Guide. To see how hardwood color changes outdoors, explore our Hardwood Weathering Test.

Aluminum Trim for a Complete Siding System

Brazilian Wood Depot also offers aluminum trim options designed for hardwood rain-screen siding systems. These trim pieces help create clean transitions at outside corners, inside corners, doors, and windows. Aluminum siding trim can improve the finished look of the project while protecting exposed edges and simplifying detail work. For compatible accessories, visit our Decking & Siding Accessories page.

Sustainably Harvested for Long-Term Preservation

Each board is sustainably harvested, supporting responsible forest management and long-term tropical forest preservation. Brazilian Wood Depot partners with suppliers who follow selective harvesting practices that help maintain healthy forest ecosystems. Cumaru, like Ipe, is subject to increased documentation and trade scrutiny, making responsible sourcing more important than ever. To understand the science, regulation, and environmental value behind responsible hardwood sourcing, explore the Sustainable Ipe Certified Interactive Course.
