Using the passive rainscreen system with modified wood siding


Damage to a home's exterior can occur in a number of ways, but more often than not, moisture is a contributing factor. Uncontrolled moisture that works its way into siding will weaken the material, either directly causing destruction (rot) or passively exacerbating an issue (giving insects an entrance). Left unattended, moisture will slowly seep into the walls behind the siding, potentially leading to some serious structural problems and expensive repairs.

An effective way of preventing moisture-related problems and ensuring that a home's structure remains unaffected is to install a rainscreen. A rainscreen system is highly recommended for homes in regions that consistently experience rain and should be considered a must for areas with high rainfall exceeding 60-inches per year.

A rainscreen system is simply an installation where an air gap is left between the siding and moisture resistant barrier applied to the sheathing. This gap allows for proper air circulation beneath your siding so moisture can drain and evaporate properly, protecting your home from leaks and moisture damage at more vulnerable areas.

How rainscreen systems work

The functionality of a rainscreen system relies on ventilation in order to effectively control moisture. In truth, it's nearly impossible to completely prevent moisture from accessing your home’s siding, so a rainscreen system provides a solution for when moisture does get behind the surface of your home’s exterior.

Properly installed siding, without a rainscreen, on a home in a dry, arid region isn’t likely to experience damage, as any moisture that moves behind the siding will quickly evaporate. The issue arises in regions that aren’t as dry and hot; when rain falls in these areas it naturally takes longer to dry up. So moisture that moves behind the siding can become trapped and without adequate airflow it’s a lot more likely to cause damage. Some moisture is important for siding. Even standard wood siding needs a small amount of moisture to remain resilient and performing well. It's trapped moisture that causes mildew, mold, and rot.

The rainscreen system provides a solution to avoid trapped moisture. The water-resistant barrier prevents moisture from directly reaching the home's wall, while the gap allows for air to circulate through, removing any moisture buildup that's behind the siding. Also selecting a more moisture resistant siding can greatly improve the overall effectiveness of your rainscreen system.

Kebony modified wood is naturally water-resistant and unlikely to experience water-damage you may see in standard wood siding. As an innovatively enhanced real wood, it’s a great solution for property owners who want natural wood siding but also need greater security and less maintenance than traditional wood siding. Kebony can be installed in a traditional rainscreen manner using vertical furring strips, or for a more cohesive rainscreen system try combining Kebony siding with the Passive Rainscreen System.

The Passive Rainscreen System uses a high-grade aluminum clip that easily provides the desired air gap you need. The clips are installed with self-tapping stainless steel screws, eliminating the need for pre-drilling holes and dramatically simplifying the installation process, saving the contractor a lot of time. Depending upon air circulation requirements, a gap size of either ¾" or ⅜" can be achieved with the Passive Rainscreen System. Part of this system involves a specially profiled siding, that fits the clip system snuggly and securely. Kebony modified wood siding can be purchased in the custom profile, making things easy and convenient for contractors and homeowners alike.

Both commercial and residential structures can benefit from the Kebony wood siding and the Passive Rainscreen System. It's quite versatile and suited to work with essentially any building exterior.

A rainscreen is an excellent investment for any homeowner that wants to extend the life of their siding while also protecting their house from moisture damage. The combination of Kebony’s outstanding performance record and the Passive Rainscreen System’s simple solution to building a solid rainscreen, makes it easy for customers to protect their home and build wisely. Considering the cost of installing a rainscreen versus the protection and peace of mind it offers makes this dynamic duo a clear winner.
