Xlafold
The Xlafold bi-folding door system has been carefully engineered to achieve the ideal balance between refined design, high performance and modern living.
Its ultra-low 15 mm threshold enables a smooth, seamless transition between indoor and outdoor spaces, improving accessibility while maintaining a clean, contemporary aesthetic. Featuring 120 mm ultra-slim sightlines, the system maximises natural light and creates bright, open living spaces.
Designed with fabricators in mind, Xlafold offers greater design flexibility alongside a faster, more efficient fabrication process. The simplified sash design removes the need for complex extensions, reduces hardware requirements and streamlines manufacturing, while pre-gasketed beads help ensure quicker, easier installation on site.
Xlafold also meets key UK industry standards, including Part L and Part M compliance, BFRC/WER accreditation and PAS 24 certification.
