Impact doors and shutters are different opening-protection approaches. Compare the exact tested assembly, approvals, design pressures, opening, exposure, installation or deployment requirements, maintenance, and limitations.
Factory-installed impact glazing does not require shutter deployment for that opening when the selected assembly and approved plan provide the required opening protection. Door function, ventilation, access, and any remaining storm-preparation steps depend on the property's complete plan.
Costs, maintenance, service life, marketability, and value vary by product, finish, hardware, exposure, installation, property, and local market. Compare written product instructions, warranty terms, and project-specific costs rather than assuming a fixed lifespan or return.
