Do you ever find the door of your business stuck open, letting in cold winter air? Do you have a door that never clicks shut, allowing strangers to sneak in, or even worse, slams shut on people as they try to step through? If so, you need an automatic door closer.
A door closer, which controls the swing of a door and guides it as it closes, can keep a door from sticking open or slamming shut. You'll need one if you remodel or build new construction since the Ontario building code now requires power door operators for disabled users. So how do you choose a door closer?
Here are some things to consider when buying a door closer in Markham.
SIZE AND WEIGHT OF THE DOOR
The type of door closer you need depends in part on the size of the door. A large, heavy door needs a door closer with a powerful spring, while a lighter door needs less force to operate. Power sizes range from 1 to 6, with a size 1 recommended for something light like a screen door closer, and a size 6 required for a 120 kg door.
If you're not sure what power size you might need, ask your installer to make the calculations for you. Many door closers can also be adjusted to fit the door during installation.
LOCATION WITH OPENING AND CLOSING FREQUENCY
Doors in high traffic areas can cycle between open and closed constantly. An exterior door will likely get more use than an interior door and because of that, the exterior door will undergo more wear and tear.
For a door in constant use, you need a Grade 1 door closer, which can handle up to 500,000 cycles per year. If your door is not used frequently, a Grade 3 door closer that handles 10,000 cycles a year will be sufficient.
MOUNTING OPTIONS AND TYPE OF CLOSER
Closures come in many types with different mounting options. Overhead closers, a durable option, work well for heavy traffic locations. Types include:
Regular arm closer, which attaches to the doorframe and the pull-side
Top jamb, which contains a box mounted on a door with a narrow top rail
Parallel arm, which has two arms that sit on top of the door when it is closed
Other options include a concealed closer, which fits into a recess in the door frame and can't be seen when the door is closed, and a floor-spring door, often used for glass storefront doors.
Backcheck is the feature on a door closer that keeps the door from slamming open. This prevents a door from being thrown open and hitting a person on the opposite side, or damaging walls and furnishings. It also stops a door from flying open in windy conditions.
If you're concerned about your door causing damage to people or property as it opens, buy a door closer with a backcheck feature.
