Stonewood Exposed Fastener (EF) Overview

EFPDS120720web

Solid phenolic core panels and exposed fastener system for use as open joint exterior cladding in a ventilated facade system. Panels attach to a one inch sub-framing system with exposed fasteners. Stonewood Architectural Panels are required to have unobstructed air flow behind the panels.

Exposed Fastening System Benefits:

  • Economical and flexible fastening system.
  • Use for all panel sizes.
  • Color matching or accent fasteners add design disguise or accent.
  • Flexible fabrication either on the job site or in factory.
  • Easily adjusts around windows and other building variations.

Panel Material Composition

Stonewood is manufactured with a core of phenolic resin impregnated kraft paper and a decorative pattern. These layers are compressed at high pressure and temperature creating a highly durable, non-porous panel. The panel is further safeguarded by a UV-protective layer and a clear peel coat for shipping and handling.

The exposed panel edges and the horizontal reveals —between the panels—are the natural core of the phenolic panel.
As the natural core ages it will develop a patina, turning from dark grey to light grey.

Phenolic Benefits:

  • Solid core phenolic panels are strong, highly durable, and impervious to moisture and bacteria.
  • Non-porous surface is easy to clean and graffiti resistant.
  • UV protective layer filters 99% of damaging UV rays.
  • Suited for all construction types and climates.
