Each panel of the Stylwall II Flat wall system is secured to the building’s structural framing and then locked into the adjacent panel, creating a smooth, monolithic exterior. This concealed‑fastener design eliminates visible screws, enhancing the clean architectural appearance while adding an extra layer of security. The result is a refined, uninterrupted wall surface that delivers both aesthetic appeal and long‑term performance.

The inside face of the Stylwall II Flat panel incorporates a built‑in rigid Thermax® insulation board that enhances the wall’s thermal performance while helping maintain the panel’s flat, uniform appearance. The tested U‑factor of the laminated Thermax core reduces the need for additional insulation, lowering material costs and improving overall wall system efficiency. This integrated design delivers consistent interior comfort, long‑term energy savings, and a cleaner, more stable panel surface.

Predesigned and factory‑fabricated transition materials make it easy to integrate Stylwall II Flat panels with other Butler Wall Systems, conventional building materials, doors, and windows—without costly field modifications. These components ensure clean connections, faster installation, and long‑term performance, and are available in all Cool Colors offered in the Butler‑Cote™ finish system.

All Stylwall II Flat wall panels feature the high-quality Butler-Cote premium finish.  Made with 70% Kynar 500 or Hylar 5000 resin, this incredibly durable coating restists fading and chalking to remain vibrant for years, unlike typical silicone polyester paints.  The Butler-Cote finish includes a real 25-year warranty against chalking and fading with an expected life span of 45 years. 

The panel’s rigid backer combines with a special joint design to allow for simple and secure installation. Each panel is positioned perfectly by nesting against the previous panel, creating a uniform joint each time. Additionally, the 16-inch panel width, combined with the side “return leg,” acts like a metal stud to allow almost any conventional flashing material to be easily fastened to the interior of the wall system.

The Stylwall II Flat Wall Panel is in stock and available cut to any length up to 40 feet, giving you fast turnaround for both new construction and replacement projects. Panels can be crated and shipped factory‑direct to your jobsite in just a few days, ensuring you get the exact size you need without delays.
