What Are Aluminum Sliding Doors?
Aluminum sliding doors are a type of door system characterized by large panels made primarily of aluminum frames and glass that slide horizontally on tracks to open and close. These doors have become increasingly popular in both residential and commercial architecture due to their sleek design, durability, and ability to provide seamless indoor-outdoor transitions.
Basic Definition and Components
At their core, aluminum sliding doors consist of several key components:
-
Aluminum Frame: The structure surrounding the glass panels is made from aluminum. This metal is prized for being lightweight yet strong, corrosion-resistant, and capable of supporting large expanses of glass without bulky framing.
-
Glass Panels: The doors typically feature large glass panels that provide visibility, natural light, and aesthetic appeal. The glass can be single, double, or even triple glazed depending on insulation and security needs.
