Choosing Overhead Door Closers

CRITICAL DOOR CLOSER SELECTION INFORMATION Corrected Door Weight Calculator - Adding door closers and ironmongery will have a disproportionate effect on the calculated door weight. It’s critical that you take into account the calculated door weight when considering the correct hinges and closers for a door. We offer this simple guide that will help you make the correct selection.

CHOOSING A DOOR CLOSER What Do I Need To Know Before I Order?

Before choosing a door closer, we recommend you have the following information to ensure you make the right choice: • Door width • Door weight - calculate using our ‘Corrected Door Weight Calculator’ below • Where is the door located in the building, i.e. children, general public, office staff, elderly or disabled users • Is the door a fire door and is it a 30 or 60 minute door • If the closer will be pull or push side mounting

Start with your actual door weight

Add [to original leaf kg]

= Corrected Door Weight

Add 20% to start weight for fitting a closer and ironmongery or add 100% if your selected closer needs a backcheck function Add 15% for heavy use doors i.e. corridors Reduce by 10% for light use doors i.e a storeroom

Example

50kg fire door blank, fitted with a back- check door closer in a busy office corridor = 115kg corrected door weight

What Are My Legal Requirements?

For fire doors, BS EN 1154 and BS EN 1155 are now required standards to which door closers must be tested. In order for door closers to be CE marked, they must be tested to this standard.

Under Part lll of the Equality Act 2010, service providers are required to make reasonable adjustments to the physical features of their premises to overcome barriers to access. BS 8300:2001 recommends that the opening force, when measured at the leading edge of the door, should be no more than 30N from the 0° (door in the closed position) to 30° open, and no more than 22.5N from 30° to 60° of the opening cycle. Doors must be a minimum of 728mm in width to be Equality Act compliant.

Hold open arms are ideal for environments where doors need to be self closing with an option to be held open. As the hold open arm overrides the function of the closer, they should not be fitted to fire doors. A GUIDE TO SYMBOLS
