General information only
This site provides general education and preliminary budgeting about automatic doors, power operators and accessible commercial entrances. It does not design, approve, inspect, certify, repair or determine the suitability of real equipment or buildings.
No guaranteed prices
Examples and calculator outputs are broad planning estimates. They do not include every possible site condition, code requirement, tax, fee, product option or labour constraint.
Professional responsibility
Costs, codes, permits, inspection duties, accessibility rules, environmental requirements and insurance conditions vary by country, province or state, municipality, building use, equipment type, installation date and project scope. Qualified local professionals and the authority having jurisdiction must determine what applies. Automatic and power-operated doors can affect accessibility, egress, fire protection, security and user safety. This site does not determine required door forces, clearances, sensor fields, activation locations, emergency operation or code compliance.
