A full-cassette awning encloses both the fabric and arms when retracted, while a semi-cassette mainly protects the fabric from above. The difference is how much of the awning is sheltered from dirt and weather when not in use. It also affects the appearance of the awning on the façade.
A full cassette offers more enclosed protection from rain and dirt, making it well suited to exposed façades. A semi-cassette is simpler and often more affordable, and may work well beneath eaves or in sheltered locations. Both provide shade when extended; the choice depends on protection, appearance and budget.
