At Firth Steels, we believe transparency should be built in, not bolted on. That’s why we’ve committed to publishing a full, product-specific Environmental Product Declaration (EPD) across each of our building envelope systems.
Whether you’re aiming to cut embodied carbon, meet planning requirements or simply specify with certainty, our verified EPDs give you the data to do it – clearly, confidently and without compromise.
Each EPD is based on a full Life Cycle Assessment (LCA) and produced in accordance with recognised international standards, including:
EN 15804
ISO 14025
ISO 21930
Rather than assumptions or average values, an EPD provides measurable data on key performance indicators such as:
Embodied carbon (Global Warming Potential – GWP)
Resource and energy use
Water consumption
Waste generation
Why EPDs Matter?
Across the construction industry, EPDs are becoming essential. As regulations tighten and sustainability targets become more rigorous, verified environmental data allows you to:
Comply with industry frameworks such as RIBA 2030, LETI, PAS 2080 and BS EN 15978.
Contribute to planning approvals where embodied carbon reporting is required.
Support ESG reporting and net-zero strategies.
Improve tender performance in both the public and private sector procurement.
Gain credits within BREEAM, LEED and other certification schemes.
Make informed, comparable decisions during product specification.
An EPD is more than a document – it’s a mark of credibility, transparency and future-readiness.
Our EPDs are independently verified by EPD Hub, a globally recognised third-party programme operator. Each declaration reflects the actual, system-specific performance of our Protex® systems, not generic material averages or offset-based claims.
Protex Classic® is our most specified built-up system, delivering consistent, regulation-ready performance across metal roofing and cladding applications. With its own verified EPD, it provides specifiers with clarity on embodied carbon, compliance and system-level impact from the start.
Protex Voyage® builds on the performance of Protex Classic® but, instead of using blast furnace steel, Steel Reborn®, our low embodied carbon offering, is manufactured using Electric Arc Furnace (EAF) steel. The result? A verified carbon saving of up to 54% versus traditional BOS-based systems.
Backed by a third-party EPD, Protex Voyage® is ideal for projects targeting net zero, planning approval or ESG investment benchmarks.
