We have carefully sourced and selected our product range to allow us to offer our customers the best quality windows and doors currently available on the European market. We are proud to offer the Internorm range of windows and doors. Internorm, is a renowned European company, currently the largest window brand in Europe…..not just the market leader but also the knowledge leader within the industry.

Their product ranges include composite timber/aluminium and pvc/aluminium triple glazed systems, aluminium entrance doors and lift and slide patio doors. Their skilled craftsmanship, innovative design and expert engineering all ensure that clients are provided with products which make their home more comfortable and aesthetically pleasing, at the same time reducing their energy bills and also requiring minimal maintenance.



Feneco Systems’ experience in the highly technical aspect of Internorm profiles and installations (with approximately 140+ installations to date) and our commitment to customer services means that we are pleased to announce that we have been awarded the status of Internorm First window Partner Gold Level . This prestigious award, combined with the company’s investment in the refurbishment of our local showroom, serves only to reinforce Feneco Systems’ long term commitment to excellence in customer service and Internorm’s faith in our company’s proven ability to complete high-end, complex installations.
