Product description
The GRILLODUR® bespoke daylighting system combines semi-transparent fibreglass panels with a self-supporting aluminium frame to create a made-to-measure solution that fits virtually any roof or façade. Its flexible design accepts a wide array of accessories and usually re-uses the existing sub-construction, avoiding reinforcement work. As a result, roofs can be renovated quickly with minimal downtime, while the system’s thermal performance helps buildings meet energy-efficiency regulations without expensive alterations to the roof structure.
Interpretation
The manufacturing of the products in this analysis involves the direct procurement of raw materials from suppliers. These materials are then transported to manufacturing facilities in the EU where they are stored, processed, and combined to produce finished products. Notably, the product stage (stage 1) has the highest impact contribution, mainly attributed to the combined environmental impacts associated with raw material manufacturing and energy used in manufacturing the products.
For products with significant manufacturing energy impacts, the shift to renewable energy sources is recommended.
Given that the raw materials used in product manufacturing have a significant impact, exploration of opportunities to substitute these materials with alternatives that have a lower environmental impact. Additionally, consideration should be given to collaborating with suppliers who employ sustainable manufacturing techniques or integrate more renewable energy into their production processes. Such initiatives can lead to more environmentally friendly products and further enhance the sustainability of the products in this analysis.
LCIA results are relative expressions and do not predict impacts on category endpoints, the exceeding of thresholds, safety margins or risks. EPDs are comparable only when they follow the same PCR, functional unit and system boundary. The full EPD (PDF) contains the methodology, scenario assumptions and verification statement.
