Bifold doors were first designed for indoor use but have lately become a preferred external sliding door alternative. The floor-to-ceiling glazing ensures a smooth transition between the inside and outside, making a striking impression. They are preferred over sliding doors since they maximize the open aperture, folding flat against the walls. Aluminum bifold doors have gained popularity in both residential and commercial properties because they’re strong, long-lasting, modern, and practical. Additionally, they offer exceptional thermal insulation properties, keeping homes and offices warm in winter.
