Premium aluminium bifold doors engineered for large openings, thermal efficiency, and lasting performance.
A Complete Door Solution for Every Project
From statement front doors to expansive sliding and bifold systems, Zyle Fenster offers a full range of bespoke, high-performance door solutions tailored to the demands of your project.
Performance You Can Specify With Confidence
Every Zyle Fenster door is engineered to meet the highest standards of thermal and acoustic performance. Whether you are specifying to Passivhaus thresholds or meeting current Building Regulations, our range offers the technical data and certification to support your project from concept to completion.
Our Aluclad construction combines the structural integrity and natural warmth of engineered timber with the low-maintenance durability of an aluminium exterior. The result is a door system that performs consistently across the full range of climate conditions, without compromise to either form or function.
Bespoke by Design, Not by Exception
No two projects are the same, which is why every door we manufacture is tailored to the specific requirements of the client, architect, or contractor. From proportions and configuration to hardware, finish, and glazing specification, each detail is considered and built to order.
Our team brings over 25 years of experience in the Irish market, offering technical support and guidance at every stage. Whether you are working on a contemporary self-build, a heritage renovation, or a multi-unit residential development, we provide the right door solution for the specific demands of your project.

Our architect specified Reynaers aluminium systems and recommended Zyle Fenster for the supply and installation.
The large glazing panels have completely changed the feel of the house while maintaining excellent thermal comfort throughout the winter. The installers were meticulous and every junction was finished beautifully.
It’s refreshing to work with a company that genuinely cares about delivering a quality result.

Our conservation project required slim glazing without compromising performance, and Zyle Fenster recommended their vacuum glazed timber sash windows.
The result is outstanding. The traditional appearance has been preserved while the improvement in warmth and noise reduction is remarkable. You simply wouldn’t know they contain such advanced technology.
Excellent communication, excellent installation and an exceptional product.
Michael & Sarah K. – County Kilkenny
Finding authentic timber sash windows that also met modern energy standards wasn’t easy until we found Zyle Fenster.
The finished windows perfectly suit our Victorian home while dramatically improving comfort. They operate beautifully and the attention to detail is outstanding.
The installation team treated our home with great respect and left everything spotless each evening. We have received countless compliments from neighbours.

We wanted a large glazed feature overlooking the garden while still achieving excellent thermal performance. The timber curtain wall supplied by Zyle Fenster exceeded every expectation.
The craftsmanship is remarkable and the amount of natural light it brings into the house is incredible. Our architect was particularly impressed with the technical knowledge and attention to detail shown throughout the design process.
Professional, reliable and extremely high-quality workmanship.
