Carbon Footprint
Carbon Footprint analysis considers all aspects in the production and erection of the system concerned: extraction of raw materials, smelting, coating, profiling, transport and erection, maintenance over a typical 60 year life and recycling or disposal at the end of life.
The data shown below considers all these aspects, including contributory products and factors i.e. energy used in production of the fixings, insulation, coatings and other accessories.The interesting factor is the significant payback at the end of the building life. Products that can be easily recycled have a reduced overall Carbon Footprint because of the relatively high initial energy cost of manufacture, and the significant benefit of recycling the steel and other materials.
Elite 1.25 with Colorcoat HPS200® Ultra pre-finished steel - kg eq. CO2 25.680 / m2
(32/1000 0.7mm Colorcoat HPS200® Ultra pre-finished steel, 170mm Eurobar spacer system, 180mm Rockwool insulation, 19/1000 0.4mm liner to achieve 0.25 U value based on 1800mm purlin centres)
Alternative products such as PIR core composite cladding panels may have significantly higher Carbon Footprints for two main reasons: firstly the chemicals used for the Polyisocyanurate foam core may have a high CO2 impact, and secondly these products are often difficult (and potentially impossible) to recycle therefore negating the significant end-of-life payback.
