UniFOLD HI is a high-performance aluminium bifold system designed for trade fabrication and 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 and multiple layout configurations. Slim aluminium profiles maximise glass area while maintaining structural integrity.
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.
The system is engineered with multipoint locking for enhanced security and is compatible with double or triple glazing. Aluminium profiles provide high strength and durability for demanding site conditions.
Thermal performance options include double glazing from 1.3 W/m²K (BFRC A) and triple glazing down to 0.8 W/m²K (BFRC A++), making UniFOLD HI suitable for high-spec residential and commercial projects.
