What you need to know about air curtains and dock door seals

  1. How air curtains work

    During loading and unloading, open doorways can let in blasts of cold or hot air and other contaminants, such as dust, moisture, fumes or insects.

    Air curtains use a wall of forced air to create an invisible barrier that people and vehicles can still pass through. This prevents outdoor elements from coming in—and indoor air from escaping.

  2. How dock door seals work

    Trailers don’t always fit snugly in shipping doors. Each little gap between the door frame and the trailer lets heat and air conditioned air escape, adding up to wasted energy costs.

    There are two ways to seal dock doors:

    • Compression seals: Foam pads form a tight seal around the top and sides of the trailer when it backs in.
    • Shelter seals: These foam frames are flexible and adapt to form a seal around the trailer sides.

Dock door seal: Only replacement of existing deteriorated seals or the addition of new seals to an existing building with shipping/receiving dock doors that do not have any type of seal in place are eligible. New construction is not eligible for this offer. If other mechanisms that combat infiltration at the shipping/receiving door are present, such as air curtains, it is not eligible. For all Industrial customers, replacement of existing deteriorated seal projects are only eligible if the incentive application is approved by an Enbridge Gas Representative. The space adjacent to the door must be heated during the heating season by natural gas fuelled equipment. Two types of seals (compression and shelter) are eligible based on door size. Compression seals (this is a foam pad that is wide and fixed to the door, with a minimum of 40 oz. vinyl cover) on 8' x 8', 8' x 9' and 8' x 10' doors. Shelter type seals (this is a curtain-like seal with minimum 40 oz. vinyl with shelter frame that is made of steel with foam pad or foam core that compresses against the sides and top of the trailer box on 9.5' x 10.5' or 10' x 10' doors. Other door sizes not listed may be eligible but must be reviewed and approved prior to application.
Existing deteriorated seals are only eligible if the incentive application is approved by an Enbridge Gas representative and if the existing seal has a minimum average 2-inch gap based on a 6-point measurement, outlined below. To qualify existing dock door seals as “deteriorated” and consider them as eligible for the Enbridge Gas incentive, a measurement form (with six points of measurement) must be completed for each door, and each seal must have a minimum average gap of 2 inches. This measurement must be taken and provided with the application form to be eligible. If a measurement form is not provided with the application, then it is not eligible. The existing deteriorated seal must have a minimum average gap of 2 inches along the seal’s side-profile projection, from where it begins at the wall to where the side-profile projection ends, determined by a 6-point measurement.

Average = [gap1+ gap2+ gap3+ gap4+ gap5+ gap6] / 6

Average = average deteriorated seal gap (inches)

  • If average ≥ 2 in. = deteriorated seal, eligible
  • If average < 2 in. = not deteriorated seal, not eligible

Please note that you are measuring “absence” of the seal (physical hole or gap) that was in place before but that is now torn.
