Scope

This document contains the PCR requirements for Insulated Metal Panels, Metal Composite Panels, andMetal Cladding: Roof and Wall Panels Environmental Product Declarations (EPDs) published incoordination with the EN 15804 and ISO 21930 standards. The requirements for the background LCAproject report used to inform the EPD are contained in UL Environment's Part A: Life Cycle AssessmentCalculation Rules and Report Requirements (thereafter "Part A"). This Part B document, coupled with thePart A, conforms to the ISO 21930, EN 15804, ISO 14025, and the US Green Building Council PCRGuidance sustainability standards for EPD reporting.

General Guidance

The scope of this PCR applies to the product group "Insulated Metal Panels, Metal Composite Panels,and Metal Cladding: Roof and Wall Panels" and includes all residential and commercially available metalroof and wall panel products according to the standards or technical approvals shown under Section 9.

Metal roof and wall panels refer to a broad category of panels composed of metal which functions asstructural elements and/or a barrier between the building and the environment. The panels may or maynot also include thermal insulation. Specifically included in the scope are:

• Construction of unpainted or painted galvanized or zinc-aluminum alloy coated steel, includingcoil and sheets. Other metals such as copper, aluminum, etc. are also covered by this PCR.
• Factory-made metal roof and wall cladding capable of functioning as structural elements to resisttransverse and in-plane loads and act as a water and air barrier, made from the above describedcoils and sheets.
• Factory-made insulated metal sandwich panels (IMP) capable of functioning as structuralelements to resist transverse and in-plane loads, provide thermal insulation and act as a waterand air barrier, with a rigid metal skin on both sides, made of the above described coil and sheetscombined with a core of foam plastic insulation.
• Factory-made Metal Composite Materials (MCM) capable of resisting transverse loading sufficientto act as a building cladding as part of either a sealed wall or rain screen system, made of rigidmetal skins with a solid thermoplastic core to provide flatness but not thermal insulation.Aluminum Composite Material (ACM) is also covered by this PCR.
