Headroom is the space between the top of the door opening and the underside of the lowest part of the ceiling above the door. An overhead door installation may still be possible even though the headroom is low. Using low headroom kits and special hardware the required headroom can be reduced to 4-1/2” depending on the door type. It is strongly recommended that you contact us in the planning stage of your building, especially for large overhead doors as they require more headroom. Inquire about Easy Lift Doors low head room options and we can determine which solution is best suitable for your overhead door.
Headroom is the space between the top of the door opening and the underside of the lowest part of the ceiling above the door. Required headroom for a commercial overhead door depends on which spring configuration and what kinds of tracks are to be used in the installation. Special follow the roof tracks, high-lift, full vertical tracks or dual-tracks can be used depending on how much headroom there is. For a standard door with torsion springs and 2” tracks with a 15” radius, requires minimum 16” of headroom. Adding for instance a trolley opener, requires even more headroom. We recommend however that you contact Easy Lift Doors so that we can have a look at your door opening and determine which tracks are best suited for your overhead door project as there are a lot of factors to consider.
Sideroom or side clearance is the measurement on each side of your overhead door opening to the nearest wall or obstruction. For smaller overhead doors allow 3” to 4” on either side and larger overhead doors 5” to 6” for standard spring and shaft configurations. If a side mounted opener is used a larger sideroom has to be accounted for to allow for fitting the opener beside the door.
Backroom or rear clearance is the distance between the overhead door and the back wall of the space where the overhead door is installed. For a residential garage door the backroom required is at least the door height plus 18”. For a commercial overhead door the requirement is door height plus 23” when 2” track is used and 25” when 3” track is used. The backroom requirement is also larger if an electric opener needs to be installed behind the overhead door.
