What Our Clients Say

Client Stories


“It was not an easy decision to replace all our windows, but I can honestly say that we now wish we had done it years ago.  The quality of the Internorm/Sunfold windows shines through.  Not only did they eliminate the draughts and cold spots making the house considerably warmer, they also gave the house a much more contemporary look.  Equally importantly, the installation and after-sales were also first rate.  In short…delighted.”

” We wanted a combination of quality and practicality in our house to take advantage of the superb views while reducing heat loss and noise from the severe weather which can happen on the north coast. We were pleased with the products and approach of Feneco in helping us choose appropriate windows, balcony and other exterior doors and balcony surround and their efficient fitting of these. The end result has achieved these aims KA Portstewart ”

We are delighted with our Internorm Passivhaus standard windows and doors. Feneco Systems did an excellent job installing our windows and doors. The installation was performed to the highest standards. We are particularly delighted with the Hires finish of our windows and the practical yet seamless appearance of the external insect screens. Our back door with low threshold provides a charming view over the mountain while letting in light to a dark corner of the house.

The high quality of the windows and doors is apparent and unmatched. When designing our passive house the hardest and key decision was our choice of Internorm windows and doors. We are confident these “class” windows will stand the test of time. The team at Feneco Systems have proved to be hard working, direct and trustworthy; exactly what you need when making a key decision.

Our analysis of windows and doors that would suit our coastal property had concluded that Internorm products would be the best technically and aesthetically. The quality of what has been installed in our house has surpassed our expectations. The team that fitted the windows and doors were efficient, skilled and extremely professional. The storms last winter seriously tested our Internorm doors and window installations – they passed everything the weather elements threw at them!!

Kind regards

 After many months of searching for a large folding/sliding door we arrived back at Feneco Systems to purchase the Internorm sliding door, we felt the quality of the door and the guarantee by the manufacturer and supplier was excellent.    The knowledge and professionalism of Peter was very good, put our minds at rest as this was a big purchase. When it came around to fitting the doors the workmanship and friendly nature of the guys was brilliant and we cannot believe they managed to fit in 1 day. We will be back when we need to replace windows and couldn’t speak highly enough of Feneco throughout the whole process.
