Both bifold door systems offered by Zyle Fenster are built to deliver high performance across thermal efficiency, acoustic performance, and weather resistance. With polyamide thermal breaks, double or triple glazing options, and robust locking systems, our aluminium doors meet and exceed current building regulations without compromise.
Finished in a wide range of colours – including dual-colour options with different finishes inside and out – our bifold doors offer durability alongside design freedom. With over 25 years of experience supplying the Irish market, Zyle Fenster brings technical expertise and genuine peace of mind to every project.

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.
