Hunter Panels is expanding their portfolio of category-leading polyiso wall solutions with the addition of the Hunter Xci AEGIS Wall System™. The new exterior wall system pairs polyiso continuous insulation (ci) with a weather resistive barrier (WRB) to increase building envelope performance while simplifying jobsite demands. A single-source solution, the Hunter Panels’ system provides protection against the elements, high thermal efficiency and NFPA 285 compliance all in one quality assembly.
The system’s Xci composite polyiso panels attach to a structural base wall (fire retardant treated wood, steel stud, concrete or CMU) in order to effectively support the cladding system. The WRB is then applied directly on top of the Xci composite polyiso panels, protecting all seams and fastener penetrations from the elements.
The multi-functionality of materials provides professionals with a complete solution for insulation, backing and weather resistance. This in turn reduces the number of trips around a building typically associated with the installation of an exterior wall system. Moreover, Hunter Panels’ strategic systemization ensures all materials are compatible and able to perform key functions within the wall assembly.
“Our system checks all of the boxes, from superior performance to protection to code compliance,” said Jason Greenleaf, Technical & Tapered Design Services Manager for Hunter Panels. “It’s the ultimate building envelope shield. Equally impressive, it streamlines installation so that professionals can build efficiently and with confidence.”
This new exterior wall system utilizes Hunter Panels’ composite polyiso products to provide ci and thermal efficiency. Users can select Hunter Xci Ply, Xci Ply (Class A) or Xci NB depending on the classification of their building type. The self-adhering Xci VP-SA WRB then serves as the system’s secondary component, providing critical defense against air and water intrusion. The elements of this systemized wall assembly are described below:
- Hunter Xci Ply and Xci Ply (Class A): designed for use with fire treated plywood backing in commercial wall applications, this rigid insulation panel has been tested within a wide assortment of National Fire Protection Association (NFPA) 285 compliant assemblies. With this designation, it’s been approved for use in Type I, II, III and IV buildings. Xci Ply (Class A) is produced with >25 flame spread foam core polyiso.
- Hunter Xci NB: intended for use with OSB or plywood backing in Type V commercial and residential wall applications, Hunter Xci NB is a rigid insulation panel that offers a simple solution for satisfying ci requirements. It also acts as a cladding attachment surface.
- Xci VP-SA WRB: a powerful safeguard designed for use in above grade wall assemblies. The vapor permeable, self-adhering weather resistive barrier provides protection against air and water intrusion while still allowing for breathability.
