The term sustainability is on everyone’s lips. But what is meant by sustainable building products?

Construction products are characterised in particular by a long usage phase. In the case of windows and doors, this is an average of 30-40 years. In addition, however, the raw material and energy balance in production, quality, energy efficiency in the use phase, as well as the possibility of repair and ultimately the disposal options, also characterize the concept of sustainability. Here, there have been established concepts for many years, which are interlinked and constantly being further developed:


The European VinylPlus® sustainability programme has been in existence for more than 20 years. In it, the PVC industry has committed itself to recycling PVC products first and foremost, as well as to establishing recycling management and CO2 neutrality as targets. This also includes the responsible use of additives, future-oriented recycling technologies and design-for-recycling, to name but a few. By the way: The exchange and replacement of stabilisers containing heavy metals such as lead was completed on schedule in 2015 due to the programme ___


Numerous quality-determining characteristics must be fulfilled and are regularly monitored by an independent body. The requirements relate to material and mechanical properties, such as permanent functionality, the so-called long-term serviceability. In addition to profile systems, insulating glass, fittings, windows and installation are also quality assured.   The RAL quality mark for PVC window profile systems is awarded to manufacturers who fulfil defined requirements for long-term usability, healthy living and environmental compatibility. In concrete terms, this means that it is ensured that no harmful substances enter the interior from quality-assured PVC windows and that attention is paid to environmental compatibility throughout the entire life cycle ___


After an old PVC window is replaced by a new one, the PVC frame can be recycled several times without any loss of quality. The recyclate flows into the new PVC profile. An increased renovation rate would consequently save more valuable raw materials and energy through recycling, which in turn reduces the emission of climate-damaging greenhouse gases. For window manufacturers and building owners who are planning to replace old PVC windows, there are recycling companies or collection points in the vicinity that take back old windows. Recycling initiatives such as Rewindo (D) and SnEp (F) offer a search function for collection points on their website ___


Through resource-saving manufacturing processes, the use of renewable energy, energy-saving plans and material-optimized product solutions, European profile manufacturers have reduced their energy requirements and thus lowered the emission of greenhouse gases such as CO2. A study has shown that primary energy demand has been reduced by around 10% in the period 2007-2017. Individual companies were even able to save 20% energy ___
