Our AliClad bifold door systems — sometimes referred to as concertina doors — feature multiple hinged panels that fold and stack neatly to one or both sides, creating expansive openings while maintaining strong weather protection and energy efficiency when closed. Precision hardware, multi-point locking and compression seals support smooth operation and reduced air infiltration, while our bifold doors also offer sound insulation up to 44dB, dependent on glass specifications.
Engineered for Australian conditions, Miglas bifold doors combine the durability of aluminium cladding with the natural insulation of timber, offering long-term stability, structural performance, and design flexibility across panel configurations. Flyscreens are included as standard.

Finishes
