Aluminum

Bifold doors can be manufactured from various materials, but GRANDDOOR bifold doors are crafted exclusively from high-performance aluminum. Aluminum allows for slimmer frame profiles and greater flexibility in size customization, creating wider openings and a more refined, modern appearance. In addition to its sleek design advantages, advanced aluminum framing plays a critical role in controlling heat gain and heat loss. This improved thermal performance helps maintain indoor comfort while significantly reducing energy consumption—resulting in lower energy bills and long-term efficiency for your home or commercial space.
