(Main)Double skin metal faced insulating sandwich panels for roofing and cladding - Environmental Product Declarations - Product category rules complementary to EN 15804 for double skin metal faced insulating sandwich panels for roofing and cladding
General Information
- Abstract
This document provides product category rules (c-PCR), that are complementary to EN 15804:2012+A2:2019, for Type III environmental declarations for sandwich panels within the scope of prEN 14509-1:2025 and prEN 14509-2:2025, which are used for non-structural and structural purposes in building envelopes and for sandwich panels with perforated faces and for sandwich panels with core materials others than defined in prEN 14509-1:2025 and prEN 14509-2:2025.
Manufactured on industrial plant, double skin metal faced insulating sandwich panels are designed to be laid with overlapping edges in the following applications:
- roofs and discontinuous roofing;
- outer walls and wall cladding;
- walls (incl. partition walls) and (suspended) ceilings inside the building envelope.
This document is intended to be used cradle-to-grave, declaring modules A1-A3, modules C1-C4 and module D, according to EN 15804:2012+A2:2019
NOTE The assessment of social and economic performances at product level is not covered by this document.

Overview
EN 18159:2026 establishes complementary product category rules (c-PCR) for Environmental Product Declarations (EPD) specific to double skin metal faced insulating sandwich panels used in roofing and cladding. Developed by CEN, this standard aligns with the requirements of EN 15804:2012+A2:2019 and covers panels as defined in prEN 14509-1:2025 and prEN 14509-2:2025. It covers both non-structural and structural products, including those with perforated faces or non-traditional core materials. EN 18159:2026 provides cradle-to-grave assessment guidance, encompassing the full product life cycle from raw material extraction through recycling, reuse, or disposal.
These insulated sandwich panels are manufactured in industrial plants and are engineered for use as roofing, external wall cladding, partition walls, and ceilings within building envelopes. The standard supports the creation of Type III EPDs, facilitating environmental transparency and comparability across the construction industry. This is vital for sustainability-focused procurement, building certifications, and regulatory compliance.
Key Topics
- Product Category Rules (PCR): Guidance specifically relating to double skin metal faced sandwich panels, ensuring EPDs reflect relevant life cycle stages and impacts.
- EPD Scope and Modules: Specifies environmental impact reporting for stages A1-A3 (production), C1-C4 (end-of-life), and D (benefits and loads beyond system boundaries), with optional inclusion of construction process and use phases.
- Material Considerations: Covers a variety of face materials (e.g., steel, aluminum, copper) and core materials (e.g., mineral wool, polyurethane, phenolic foam, EPS, XPS).
- Reference Service Life (RSL): Guidance for declaring an RSL (at least 50 years) based on typical product performance under standard conditions and appropriate maintenance.
- Lifecycle Assessment (LCA) Requirements: Instructions for inventory analysis, data quality, system boundaries, and allocation of impacts in compliance with EN 15804.
- Waste and End-of-Life Scenarios: Includes models and recommended data for deconstruction, transport, recycling, reuse, and disposal at the product’s end-of-life.
- Additional Environmental Indicators: Addresses the declaration of supplementary indicators, in line with national requirements or specific market demands.
- Transparency in Communication: Mandates clear and standardized presentation of EPD content for ease of comparison and decision-making.
Applications
Double skin metal faced insulating sandwich panels are widely used in:
- Roofing and Discontinuous Roofing: Providing thermal insulation, weather resistance, and structural performance for various building types.
- External Walls and Cladding: Supporting energy-efficient facade solutions and modern architectural designs.
- Partition Walls and Ceilings: Delivering lightweight, insulating, and quick-to-install options for internal building applications.
The EPDs prepared in line with EN 18159:2026 are valuable for:
- Architectural and construction professionals seeking to evaluate and compare the environmental impacts of building materials.
- Manufacturers aiming to demonstrate sustainability credentials to clients, specifiers, and certification bodies.
- Organizations participating in green building rating schemes (such as BREEAM or LEED), where verified EPDs are required.
- Regulatory compliance, especially where product transparency and environmental performance reporting are mandated.
Related Standards
To ensure comprehensive application and alignment of EPDs for double skin metal faced insulating sandwich panels, the following standards are closely related:
- EN 15804:2012+A2:2019 - Core rules for the environmental product category of construction products.
- prEN 14509-1:2025 and prEN 14509-2:2025 - Product standards for factory-made double skin metal faced insulating sandwich panels for self-supporting and structural applications.
- EN 16783:2017 - EPD product category rules for factory-made and in-situ formed thermal insulation products.
- EN ISO 9229:2020 - Thermal insulation - Vocabulary.
By adhering to EN 18159:2026, industry stakeholders can ensure that EPDs for sandwich panels are robust, regionally harmonized, and effective in supporting the sustainability objectives of the built environment.
