Frequently Asked Questions

Sustainability in the building sector should be considered from many different angles, both on building and product level. Our joinery systems are made of one of the most circular materials available, aluminium. It can be recycled an infinite amount of times, without loss of quality. Moreover, as a standard, we provide low carbon building elements, such as low-carbon aluminium profiles and thermal breaks. Reynaers Aluminium is ASI Standard certified, meaning that the aluminium we use in our systems is ethically sourced, with respect for people and our planet. And we participate in local closed-loop systems to limit waste and support end-to-end traceability.

Next to responsible sourcing tactics, we apply Eco Design principles that help minimise the impact of our systems even further. Increasing the lifespan of our solutions and buildings starts at the drawing board by designing out waste, designing in modularity, designing for adaptability and flexibility, designing with disassembly in mind, ... Nothing is left to chance.

Most of our systems come in multiple insulation levels, down to Passive House thermal performance. By focusing on energy efficiency and weather performance, tested and verified in our expansive Technology Centre, we help limit the operational carbon emissions of buildings drastically.

Finally, by providing clear and official documentation, we can help professionals earn green building certificates and navigate sustainable legislation more easily. We are your expert guide that provide the right tools and solutions for your building needs.

While "low-carbon" primary aluminium is not formally defined, it encompasses all virgin material with a carbon footprint equal to or lower than 4.38 kgCO2/kg aluminium (billet + extrusion). In practice, low-carbon aluminium is a mix of recycled aluminium and low-carbon primary aluminium produced with clean energy.

An Environmental Product Declaration (EPD) is a third-party verified, internationally recognized disclosure of a product's environmental impact throughout its lifecycle. EPDs are voluntarily developed and their overall goal is to provide relevant, verified and clear information regarding the environmental performance of products. The basis of the EPD is a Life Cycle Assessment (LCA) of the product, in accordance to ISO 14025 and EN 15804+A2.
