A high-performance aluminium window system offering three insulation levels, from high-insulation to Passivhaus-certified, behind consistently clean external lines.
High-Performance Aluminium Windows for Modern Buildings
Our range of aluminium windows brings together slim profiles, thermal break technology, and exceptional design flexibility – offering the perfect choice for contemporary homes, new builds, and architect-led projects across the Ireland.
Precision Engineering Meets Clean, Minimalistic Design
Aluminium window frames offer a modern look that suits both contemporary homes and period properties requiring a sleek, considered aesthetic. With thin frames and slim profiles, our aluminium windows allow more natural light into the spaces that matter most.
The inherent strength of aluminium frames means larger glass panels are achievable without compromising structural integrity – delivering unobstructed views and a minimalistic design quality that architects and self-builders consistently specify by choice.
Outstanding Thermal Performance Across All Weather Conditions
Every system in our range of aluminium windows incorporates advanced thermal break technology, significantly reducing heat transfer through the frame and minimising heat loss across all weather conditions. Whether specified with double glazing or high-performance triple glazing, our aluminium window frames consistently deliver low U-values that support modern homes in meeting and exceeding current energy efficiency standards.
With options certified to Passivhaus standard and systems suited to low-energy builds, our aluminium windows offer peace of mind through performance – not just promise. Available across a wide range of RAL colours with durable powder coating, each window is finished to the highest standards of quality and longevity.

We purchased a combination of Alu-Clad windows, Lift & Slide doors and entrance glazing from Zyle Fenster for our family home.
Every member of the team was knowledgeable, approachable and highly professional. Manufacturing quality is outstanding and the installation was carried out with real attention to detail. Even after completion, they followed up to ensure everything was perfect.
It’s rare to find a company that delivers exactly what they promise. We would happily recommend Zyle Fenster to anyone building or renovating a home.

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.

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.
