What Sets Hoyme Apart
Four reasons contractors specify Hoyme, wholesalers stock it, and inspectors recognize it.
Built for Compliance
Motorized, automatic dampers designed to help meet NECB, MNECH, CSA B149.1, B139, and U.S. combustion-air and ventilation requirements.
Canadian Manufacturing
Designed and built in Camrose, Alberta. Consistent construction, clear labeling, and reliable performance across every unit for over 40 years.
Installer-Focused Design
Clean wiring diagrams, interlock-ready controls, and clear sizing guidance reduce install time and keep inspections moving.
Energy & Comfort Benefits
Closable dampers cut standby heat loss, reduce drafts, and support energy-efficient homes — comfort homeowners notice and contractors take credit for.
Trusted by contractors and wholesalers for over 40 years.
The same approach inspectors, utilities, and code officials have recommended since the 1970s.

Built for Code Compliance and Safety
Modern codes in Canada and the United States expect controlled combustion air and mechanical ventilation — not passive openings or manual dampers.
Motorized Automatic Operation
No manual blades permitted in combustion-air ducts. Dampers must open and close automatically with the appliance.
Interlock-Ready Wiring
Appliances cannot fire unless the damper is confirmed fully open. Hoyme ADP relay adaptors make this wiring straightforward.
Clear Sizing Guidance
Damper size is determined by total appliance BTU input. Hoyme provides clear sizing tables so contractors and counter staff get it right every time.
