With only 110mm sightlines and a great thermal performance, UniFOLD HI is the perfect choice to create a brighter, more luminous space for any project.
UniFOLD HI is a high-performance aluminium bifold system designed for trade installation. It features snap-in pre-gasketed glazing beads and smooth-running roller hardware for reliable, quiet operation and fast assembly.
The system is configurable to project requirements, with inward or outward opening options, multiple layout configurations, adjustable jambs and low threshold options.
Slim thermally broken frames deliver strong thermal performance without compromising on sightlines, making UniFOLD HI suitable for residential and light commercial applications where performance and aesthetics are key.
UniFOLD HI offers full design flexibility with single or dual RAL powder-coated finishes and colour-matched hardware for a clean, consistent aesthetic. Durable powder coating ensures long-term colour stability and resistance to fading or cracking.

Thermal performance options include double glazing from 1.3 W/m²K (BFRC A) and triple glazing from 0.8 W/m²K (BFRC A++), making UniFOLD HI suitable for high-spec residential and commercial projects.
