Product description

Louvers are essential to any successful building. They provide healthy air exchange, while ensuring unwanted elements, like rain, dirt, and animals remain outside. Louvers provide an extra architectural element to a building’s exterior – giving an opportunity to improve the look of any building while meeting mechanical requirements. Louvers include an aluminum body, fasteners, and hardware. Various models may also contain steel, actuators, bearings, seals, and/or insulation. Aluminum is sawed, punched, machined, and welded for the specific project. Once the louver is assembled and welded, it can optionally be sent through the paint line before being packed and shipped to the installation site.

Interpretation

The analysis of Greenheck’s Louver products provides useful insights regarding the cradle-to-grave environmental impacts. The LCA results also identify where substantial impacts are occurring to allow further process and materials improvements to be implemented by the reporting company. The cradle-to-grave impacts for all products are dominated by the A1 Raw Materials Extraction and Processing stage. This stage accounts for 75%-93% of the impacts throughout the products' lifecycle. After this the second largest contributor is the A3 Manufacturing stage. This stage accounts for 6-19% of the lifecycle impacts. The A2 Raw Material Transportation stage accounts for 0.4-3.5% of the impacts, with the other stages accounting for <2%. The trends are similar among the other products assessed. Another key driver of the impacts is the B4 Replacement stage, this is due to the 1.5 replacement products needed to satisfy the 75-year requirement for the functional unit.
