Same factory, two different façades.
SJ Jalousie is built for the people inside. Its 135mm blades open to 80° for maximum airflow, and they're backed by built-in security bearers and fall prevention compliance for schools and exposed sites.
SJ Espacer is built for the building's face. Its 235mm blades span up to 1800mm in a thermally broken frame, and it integrates with stick or unitised curtain wall. Fewer lines, more glass, façade scale.
The full comparison is in the Selection Chart on the SJ website.
