General Composite Cladding FAQ
What type of weather barrier should I use?
Fiberon recommends installing a highly UV-resistant rainscreen weather barrier with Wildwood composite cladding. Note that the air gap between the weather-resistive barrier and exterior cladding can be as narrow as 3/8 in. This will still enable drainage and drying. Consider using a dark-colored air barrier to conceal gapping.

FLORIDA PRODUCT APPROVAL NUMBER
Set by the state of Florida for all construction trades. Products with this designation have been approved for use throughout Florida, including in Hurricane Zones. Specifiers should request the Product Approval page as evidence of approval. Once a product has been awarded a Florida product approval number, no state building commission can require additional testing, evaluation, or documentation.

TEXAS DEPARTMENT OF INSURANCE PRODUCT EVALUATION
Approval means our product has been evaluated for compliance with the wind loads specified in the International Residential Code (IRC) and the International Building Code (IBC). To learn more, visit http://www.tdi.texas.gov
NFPA 268 Standard Test Method for Determining Ignitability of Exterior Wall Assemblies Using a Radiant Heat Energy Source. Used for code and other regulatory purposes, specification and design purposes, and research and development activities. Conducted under controlled laboratory conditions, this is a testing methodology to measure and describe the ignitability characteristics of exterior wall assemblies and their potential of contributing to fire growth. Fiberon cladding products meet the standard.

What is Fiberon's expertise in composite cladding?
Fiberon has worked to advance the appearance and performance of composite building materials without sacrificing our commitment to sustainable, eco-friendly manufacturing. We have led the way with innovative solutions that have become industry standards:
- First molded and embossed solid, reversible wood-plastic composite (WPC) decking (1999).
- First WPC decking with comprehensive spectrum of performance additives (2004).
- First reversible, capped composite decking with multi-chromatic technology (Horizon, 2008).
- First stain and fade warranty on capped composites (2009).
- First cellular foam PVC decking with tropical, multi-chromatic technology (2013).
- First composite cladding warranted for rainscreen applications (Concordia, 2015).
- A high-performance, low-maintenance product created specifically for cladding and rainscreen applications (Wildwood, 2021).
- An exclusive cap layer that protects against fading and staining (PermaTech).
With its roots in decking applications, our composite cladding provides a level of durability, longevity and resistance to cracking, peeling and fading that other common cladding materials simply can’t match. Plus, Fiberon Wildwood composite cladding never needs staining, sealing, re-painting or refinishing, which significantly reduces long-term costs of ownership.
Does Fiberon provide a complete rainscreen system solution?
Fiberon offers a durable composite cladding that provides an elegant wood-like façade for a rainscreen application. Cladding is only one component within a rainscreen system.
Other elements include: weather-resistive barrier (rated for continuous UV exposure), furring material, and flashing at all penetration points and cladding transitions.
Note that the air gap between the weather-resistive barrier and exterior cladding can be as narrow as 3/8.” This will still enable drainage and drying.
Fiberon composite cladding is a smart choice for rainscreen applications because it is easy to source, install, and maintain; does not absorb water readily; and is available in a wide range of rich wood tones, each with multi-tonal streaking and authentic grain patterns.
Where can I find Fiberon Wildwood composite cladding?
Contact customer support for additional information on samples and obtaining Wildwood composite cladding for your project.
Why would I choose a decking product for a rainscreen application?
Fiberon composite boards have been tested and trusted by contractors for years. They have been designed and manufactured to withstand the rigors of regular foot traffic without sacrificing appearance or performance, so you can feel confident when specifying them for cladding projects.
Plus, unlike ordinary cladding options, Fiberon composite cladding won’t peel, split, crack, or rot. It’s dimensionally stable, easy to install, and absorbs only negligible amounts of water – unlike brick or stucco, which absorb water quite readily.
