Strategic approaches to cladding design
The cladding system may be designed to provide a protected or exposed frame.

The performance and complexity of construction of a particular system can be greatly influenced by certain strategic responses to the envelope design. The relationship between the frame and the cladding, exposed or protected, is important both in terms of performance and expression.
In a protected frame, the structure is completely enclosed by the cladding.
The cladding protects the frame from the weather and extremes of temperature. The connection of the cladding to the frame is easier than in the case of the exposed frame. The expression of the cladding may be completely independent of the frame behind.
