The Insulbar RE from Ensinger, a global developer and producer of thermal insulating profiles for window, door and façade construction, is the first ever thermal insulating profile for metal frames made of recycled materials. This insulating profile which creates a thermal barrier between metal frames is made from 100% unmixed polyamide (PA) recyclate, and this can help reduce heating and air conditioning costs.

Insulbar RE is made of 100% unmixed recycled PA. This base material is upgraded using a special process to lend it properties on a par with new material. This process extends the useful life of this high-grade material by another complete product life cycle, actively protecting the environment and helping to slow climate change – and has consequently been dubbed “upcycling”.
On the technical front, since PA66GF25 is continuing to be used in Tecatherm 66 GF RE, heat conductivity is in accordance with the materials standard Tecatherm 66 GF. According to Ensinger, Insulbar RE is suitable for all articles, therefore the same U-values will be achieved as with the standard Insulbar products. At the same time the U-values can also be improved by means of optimised geometries and functionalisation of the profiles, says the company.
Processing
The process used by Ensinger to “upcycle” the PA recyclate is fully in compliance with the stringent Insulbar quality standards as set out by DIN ISO 9001: 2008. According to the company’s own account, the composition and properties of the material are exhaustively tested and documented at every processing stage. This is said to ensure that Insulbar RE comes with the same high quality credentials users have come to expect from the classical Insulbar profiles: as well as being energy efficient, insulating profiles made of recyclate provide good mechanical properties, durability and functional reliability for years to come.
The focus of the Insulbar RE project has been on improving sustainability whilst at the same time maintaining uniform processability and high economic efficiency.
