Established For Over

20 Years

1st Class Window Systems Ltd was established in 1995 by Paul Trigwell on our present site in Westham – on the outskirts of Eastbourne, in East Sussex and the goal was to manufacture uPvc to a high standard using Rehau profile and top quality hardware. We aim to give a more personal service and the backup of knowledge that the customer expects.

The aluminium department opened in 2013 with the same principles applying and using Smart systems aluminium extrusions, who like Rehau, are a well established often specified system.


Our Investment In


Here at 1st Class we have always believed that ‘a workman is as good as his tools’, and to that end we reinvest heavily in machinery for our factory and our staff to equip them with the best to achieve a consistent quality finish.

We provide a delivery service that covers all the South East including Kent, up to London and over to Hampshire and beyond by arrangement.
