Dock Door Seals
Whenever a dock door is opened during loading or unloading activities, infiltration losses occur between the truck and the door when the truck trailer is pulled up to the dock door. There is a solution to this issue – Dock Door Seals.
Dock Door Seals reduce the infiltration losses at the shipping and receiving door and during loading and unloading operations, by “sealing” the gap between the truck and the dock door. This can be done by either surrounding the dock with wide pads and compressing the trailer (this is called a compression seal), or with a foam frame that compresses against the sides and top of the trailer box, which is a shelter/curtain seal.

Service Provider Incentive
- 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 fueled 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 min. 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 a minimum of 40 oz vinyl cover 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 buy must reviewed and approved prior to application.
- Existing deteriorated 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 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 = 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.
