Where It's Used
Residential Projects
Clerestory Window products may be used in residential work when the configuration, finish, maintenance expectations, and performance ratings match the opening.
Commercial Projects
Commercial applications should verify traffic level, code requirements, tested assemblies, submittal documents, and serviceability.
Replacement and Retrofit
Retrofit work should confirm existing dimensions, substrate condition, surrounding finishes, and whether the product can be serviced after installation.
Custom or High-Exposure Conditions
Large sizes, severe weather, unusual geometry, coastal exposure, fire ratings, or acoustic goals usually require early manufacturer review.

Details To Confirm Early
01
Confirm the opening geometry
Special shapes, projections, pivots, and roof-plane conditions need final rough opening dimensions before ordering.
02
Review glass size and weight
Large or unusual glass shapes may require tempered, laminated, thicker, or factory-glazed units.
03
Coordinate flashing and drainage
Nonstandard geometry puts more pressure on sill pans, head flashing, weeps, and exterior water management.
