Why use Real Rain Screen™ siding?

Natural Beauty

Nothing beats the beauty of Real Wood. Shiplap siding of Ipe, Purpleheart, Massaranduba and other premium hardwoods is unique in appearance and many choices are available for color preference.


RealWood˙ hardwood lumber is rated to last a lifetime - 40 to 100 years! Real Rain Screen™ siding also provides better protection from mold causing moisture than other construction methods.

Easy to Install

Our signature H-clip and siding profile system makes installation easy. Installation provides channels in the walls, which allow the siding to breathe eliminating moisture and minimizing thermal transfer

Maintenance Free

Brazilian hardwood does not need any painting or finishing. It will remain durable and rot resistant for a lifetime. Finish application is required for color maintenance but not to maintain durability.

Hardwood Species Guide

Premium RealWood™ hardwood provides unsurpassed durability and beauty. RealWood™ hardwood is naturally resistant to rot and decay and harvested in the Central and South Americas. No pressure-treating with protective chemicals is required. Pressure treated siding requires annual maintenance to retain its termite protection and resistance to rot and decay. Softer woods like oak, redwood and pine are not as realwood certifiedresistant to weather and rot and are easily eaten by bugs. Because it is naturally resistant, RealWood™ hardwood remains maintenance-free*.

Ipe Decking

Ipe Decking (Brazilian Walnut) is olive-brown to dark-brown in color. Ipe is one of the hardest and most durable woods found anywhere in the world. A fantastic choice for residential decking and siding, as well as commercial applications due to its strength and longevity.

tigerwood decking

Tigerwood decking is orange-brown, but will darken and display deeper, reddish hues over time when used outdoors. That unique orange tint makes Tigerwood hardwood a one of a kind choice for interior home projects as well.

garapa decking

Garapa decking is a blonde or wheat-brown which will also darken and become an amber-tinted brown over time. Garapa wood is used for everything from flooring to decking to cabinet work and heavy carpentry applications -- even ship building.

cumaru decking

Cumaru Rosa (Red) hardwood is a reddish brown to deep, cherry red, with beautiful grain patterns. Strength is nearly comparable to Ipe's legendary hardness rating.

massaranduba decking

Massaranduba (Brazilian Redwood) is a beautiful plum red tinted to reddish-brown color. It's known for a lack of visible knots, and a consistent grain with subtle demarcation partially due to the dark, deep color.


Purpleheart hardwood decking lumber is resistant to insect attack and decay. It is one of the densest woods on the planet and is VERY durable. Purple Heart hard wood grows in many areas of South America and is easily sustainable. The Purple Heart tree is large, attaining heights of 100 to 150 feet, with diameters of 36 - 60 inches.

Installation Tips

hardwood siding installation

Real Rain Screen™ installation requires furring strips fastened to exterior walls over a vapor barrier. Siding is fastened to furring strips – most commonly with 16” centers. Our coated aluminum H-clips are installed using our Magni 599 rust and salt water resistant coated square drive screws. This installation provides channels in the walls, which allow the siding to breathe eliminating moisture and minimizing thermal transfer. For additional installation information, visit the Brazilian Wood Depot Documents Page.

Entrapped moisure is not only a problem in wet climates. Even in dry areas, moisture trapped in  a wall system can result in rot, rust, and mold. The structural integrity of the wall is at stake, as is the health of the occupants. Proper installation is crucial to the effectiveness of Real Rain Screen™.
