Use life reaches at least 40 years, which means less use of resources and a lower C02 emission burden. In theory, a cycle of window use and recovery can be repeated seven times without negative effects to raw materials or processing quality. It is not only surplus production material and profile off-cuts arising from window production that are recycled here, but meanwhile also old windows, worn-out doors, roller shutter slats, etc. According to the Rewindo.de association jointly established by PVC window producers to encourage PVC window recycling, a recycling rate of 89 percent is achieved with old windows, corresponding to 101,000 tonnes of recovered PVC granulate. Within this amount, 73,645 tonnes is accounted for by production waste and 27,328 tonnes by recycling of old windows. Construction of PVC windows PVC window profiles are produced out of particularly high-grade PVC. A long-life, high-grade plastic with optimum use properties is obtained through use of additives such as UV stabilisers, pigments, fillers, etc. The advantage of such PVC compounds is their universal recycling capability. This means that profile off-cuts and of course also old windows can be recycled at a...
