Your Shipping Doors Are Costing You More Than You Think
Energy Savings Program for Small Businesses In Ontario
If your facility has shipping doors, you are likely losing more heat and more money than you realize. Through the Enbridge Gas Small Business Program, Ontario businesses can access significant incentives on air curtains and dock door seals, with installation handled by our trained technicians. At Lenworth, we manage the entire process from assessment through completion, so you can focus on keeping your facility running.
What Is Covered?
Rideaux d'air
Air curtains create an invisible wall of forced air across your doorway, blocking outdoor elements from entering while still allowing vehicles and personnel to pass freely. They are one of the most effective tools for maintaining indoor temperature control without interrupting your operation.
Air curtains are available on both dock-in and drive-in door configurations.
Dock Door Seals
Dock door seals close the gap between your building and an inbound trailer, dramatically reducing air infiltration during loading and unloading.
Two seal types are available depending on your door configuration: compression seals and shelter seals. Both are designed to minimize heat loss and keep out dust, exhaust, and outdoor air.
