About Us

How Panel+ Works

Adhesive-Applied: The Fluid Applied Adhesive method for the Panel+ wall system creates a durable bond between EPS Foam Panels and various substrates. This specially formulated adhesive mortar ensures high strength and flexibility, delivering a resilient, long-lasting build that meets the demands of modern construction. Achieve secure, reliable installation with a straightforward application process that enhances structural integrity.

Mechanically Fastened: The mechanical fastening method for the Panel+ system uses 2-inch polymer-based washer fasteners designed to securely hold insulation panels of any thickness. These fasteners prevent pop-ups and maintain stability, even in challenging environmental conditions. Built for durability and performance, they ensure a reliable, long-lasting installation that withstands the demands of modern construction.

  • EPS Foam Panels – R-4.8 per inch, customizable thickness.
  • Integrated Guide Channels – Perfect veneer alignment.
  • Old Mill Weather Barrier – Fluid-applied air & water protection.
