Anglian Building Products’ Environmental Management System has been accredited to ISO 14001.


Anglian have been recycling both factory waste and 1st generation PVC-U windows for many years. 1st generation is the name for old PVC-U windows which are being replaced.

Whilst the 1st generation frames are normally still functional, the glazing system may be low security and many of the windows are single glazed, also the locking mechanism is often very basic. Our clients have decided to replace them to improve the security and energy efficiency. We will either return these frames back to Norwich for onwards recycling, or work with a local recycling specialist depending on the project logistics.

We use the PVC-U recycled material on a very controlled basis. We use advanced co-extrusion techniques to produce sections with virgin material in critical areas and recycled material elsewhere. The images below show in green where the recycled material is used.

Where do we use recycled material?

The uses are controlled by BS EN ISO 12609. The placement of the recycled material varies depending on the recycled material colour and only window grade materials are allowed back into our products. We use it only in hidden areas, it is often used as a base over which a new PVC-U skin is applied. Until recently this has been largely limited to the 150 mm external cill, but now this has been extended to the White Knight outer frame profile. This is the highest runner used in our factories. This now means that a typical window has a recycled content of around 25%.

The image below shows the new frame section, a green pigment has been added to the recycled material for illustration purposes.
