Established in 1996, Carlisle Window Systems Ltd have been providing home owners and businesses throughout the UK with top quality windows, doors and conservatories for many years now. Our family-run business began when the Directors first started installing windows before the days of PVC back in the 1980โs. Installations have been done all over the UK, from prestigious mansion houses to vast high
-rise developments, working with all types of materials including timber, aluminium and composite all before the introduction of PVC which is now the product of choice when it comes to windows, doors and conservatories. In 1996, Carlisle Window Systems Ltd began trading. In 1999 we began manufacturing our own uPVC Windows & Doors. In early 2025, we continued to provide our clients with the very best by expanding our production line to now produce Aluminium in our Factory on Eastern Way in Carlisle. Our philosophy is simple: we aim to offer traditional virtues of quality, design, service, craftsmanship and respect for all of our customers. Combine these virtues with a commitment to creating advanced products, using the best in modern materials and technology and provide a service that results in happy and satisfied customers every time.
