Carlisle Windows Systems Ltd are introducing a brand new range of high-performance Aluminium Windows, Single Doors, French Doors, Bifold Doors, Sliding Patio Doors & Flat Roof Lights - all produced right here in our Carlisle factory.

Project Type: Launch of in-house Aluminium Product Range

Location: Our Production Facility in Carlisle, Cumbria

Date: April 2025

Overview –

Carlisle Windows Systems Ltd is proud to announce a major investment in our own in-house aluminium production line, enabling us to manufacture a brand-new range of high-performance aluminium products - right here in our Carlisle-based factory.

This strategic move represents a significant step forward in our commitment to delivering better products, faster service, and unbeatable value to our customers.

The Challenge –

Until now, our aluminium product offering relied on outsourcing. While this allowed us to meet demand, it also introduced unavoidable limitations:

• Longer lead times
• Less control over product quality
• Reduced flexibility on custom orders
• Higher costs passed on to our Clients

We recognised that to grow, compete, and lead, we needed to bring aluminium production in-house.

The Solution –

We’ve invested in advanced aluminium fabrication equipment and a dedicated team to launch our own aluminium manufacturing line - a move that allows us to introduce SIX new aluminium products to our range:

• Aluminium Windows
• Single Residential Doors
• French Doors
• Bifold Doors
• Sliding Patio Doors
• Flat Roof Lights

Each product is crafted with precision using slimline, high-performance profiles, delivering sleek aesthetics and superior energy efficiency for both domestic and commercial projects.

The Conclusion –

This expansion marks a milestone for Carlisle Windows Systems Ltd. By manufacturing our aluminium range in-house, we’re supplying our customers with better products, better service, and better prices - all without compromise.

Whether you're a homeowner, builder, or developer, our new aluminium line is designed to meet the highest standards of performance and style.
