Aluminium Bifold Exterior Doors

   Aluminium bifold exterior doors, also known as aluminum folding exterior doors, are a popular choice for modern architecture due to their functionality and aesthetic appeal. Here is an introduction to them:

Characteristics

Space - saving: Aluminium bifold exterior doors fold back on themselves and slide along a track, occupying very little space when open. This makes them ideal for areas where space is limited, such as small balconies or patios.

Large - scale opening: These doors can be configured with multiple panels, allowing for a wide - spanning opening when fully unfolded. This creates a seamless transition between indoor and outdoor spaces, perfect for entertaining or enjoying a panoramic view.

Durability: Aluminum is a strong and lightweight material that is resistant to corrosion, rust, and warping. This makes aluminium bifold exterior doors suitable for long - term outdoor use, even in harsh weather conditions.

Energy efficiency: Many aluminium bifold exterior doors are designed with thermal breaks and can be fitted with double - or triple - glazed glass, which helps to improve insulation and reduce heat transfer, thereby enhancing energy efficiency.

Common Specifications

Aluminium profile thickness: Usually, the thickness of the aluminium profile ranges from 1.4mm to 2.0mm. For example, the AMJ75 series of aluminium folding doors has a standard profile thickness of 2.0mm, which ensures stability and strength.

Glass configuration: Common glass configurations include single - layer tempered glass, double - glazed tempered glass like 5mm + 12A+5mm, and triple - glazed tempered glass. The choice of glass depends on factors such as insulation requirements and glass strength.

Hardware fittings: High - quality hardware, such as hinges, handles, and tracks, is essential for the smooth operation of bifold doors. Brands like Riesman and Pai Ge are often used for hardware fittings.
