What is the difference between captive and non-captive aluminium framing?

Captive aluminium framing refers to systems where the frame components are designed to be enclosed or fixed within a specific structure, often providing enhanced stability and support. Non-captive aluminium framing, on the other hand, allows for more flexibility and modularity, enabling components to be easily removed or reconfigured without compromising the overall integrity of the structure. This distinction affects their applications, with captive systems typically used for permanent installations and non-captive systems suited for dynamic environments.
