Welcome to Asset Fineline, Commercial Division of the A&B Glass Group.

Asset Fineline was formed after the Acquisition and subsequent merger of Asset Manufacturing in Thetford back in 2005 and shortly after Fineline Commercial in Rochester. Both companies individually had an esteemed history and commercial reputation regarding the manufacture and installation of PVC-u and Aluminium windows, doors and associated products.
Our clients now include Local Authorities, Healthcare and Education providers and Main Contractors.
This website provides further details including case studies of our completed developments. You can also take a factory tour by watching our video and learn how our windows and doors are made at our manufacturing plant in Sudbury, Suffolk.
