Here is how the industry works: the specifications above define the baseline for a functional entry door with sidelights and transom. As a manufacturer, our approach at Jusen Door and Windows is to meet these standards within a direct-supply model.
We produce fiberglass, wood, and thermal-break aluminum entry door systems, including full configurations with sidelights and transoms. Because we operate the factory, we can adjust the profile structure and fittings to match the building codes of your target market—whether that means a specific rough opening dimension, a particular low-E glass specification, or hardware that meets local security standards. This is relevant when your project requires compliance with local regulations rather than a one-size-fits-all import.
Our pre-shipment inspection includes air-tightness, water-tightness, and wind resistance testing on the completed unit. This matters for sidelight and transom systems specifically because the multiple glass-to-frame joints are where failures occur—a unit that passes these tests is less likely to leak or draft after installation. We also provide full export documentation, including packing lists, proforma invoices, and customs paperwork, which simplifies the logistics of FCL or LCL shipment from our factory.
For buyers sourcing entry door systems, the evaluation criteria are the same whether you purchase domestically or import: does the manufacturer meet the specification, can they prove it through testing, and can they deliver the documentation your project requires? If you are comparing suppliers and want to discuss your rough opening dimensions or glass specifications, our team can provide the technical details you need to finalize your decision.
