PVC Window Manufacture

In-house Supply Chain

We have a in-house PVC-U window and door supply chain. This gives us a significant competitive advantage as we have control of all processes from initial design, survey, manufacture, installation to after sales support.

The benefits of our in-house supply chain are that it provides you with certainty of:

  • Quality
  • Time
  • Costs

In addition it gives us greater control of CSR issues such as sustainability and business ethics. This contrasts with the majority of our competitors who typically fabricate products using components from a multitude of external sources.


Research & Development and Design

Anglian’s in-house teams ensure that Anglian products are designed to exceed industry standards, and maximise product life cycles. Our current focus is very much on sustainability issues, increasing the use of recycled materials and improving the energy efficiency of our products. The Design Department focus both on new products and bespoke fenestration solutions.

Raw Material Supply

Anglian’s position as market leader provides us with enormous buying power. Our procurement department uses the latest innovative procurement techniques to ensure best value is achieved. All supply chain partners are engaged on formal Service Level Agreements with a strong focus on efficiency, performance management and collaborative working.


We blend the PVC-U raw materials in-house to give certainty of quality and consistency. We then extrude over 150 different extrusion sections in our dedicated extrusion facility. The range of profiles include main window and door frame sections, trims, fascia, soffit and gaskets. All are extruded to strict quality standards including BSI Kitemarks.

Glass Processing

Our Glass Shop utilises computer optimised glass cutting tables to minimise waste, glass is then toughened as required using our huge furnaces ready for assembly into double or triple glazed units. The Insulating Glass lines assemble the individual panes with the spacer bar and sealant to produce sealed units of the exact specification and size to meet individual requirements.


Our computer controlled optimised machining centres automatically cut and route the PVC-U sections ready for reinforcing if required. Each section is then welded into a frame and the weld sprue is removed utilising robotic handling devices. Each frame is individually identified by a barcode. The frames and casements are assembled together with the hardware. All glazing is packed into position with special retained packers which ensures that the finished product is set-up ready for installation. Each completed product then undergoes a final inspection and is identified as ready for despatch. The whole process is co-ordinated to ensure that products are ready for delivery to meet the required installation date.


All products are delivered to site via our in-house Distribution Department. Deliveries are optimised based on just-in-time principles and minimising our environmental impacts.


Installation is undertaken by trained and experienced personnel in accordance with the Anglian Installation Manual. All Installers wear uniforms and drive liveried vans.


We seek to minimise site waste, recycling whenever practical.
