RESIDENTIAL & SUSTAINABLE LIVING


elderly, more vulnerable users and those with a disability, hold-open door closers enable doors to be held open so that these individuals can move about more easily. Another important door closer functionality is free-swing, which can also be installed as a means of easing access. These are also ideally suited to environments that experience high volumes of traffic, such as offices, educational sites, hotels and commercial spaces. Free-swing, like hold-open, can help to increase the fire safety of a building. These are typically installed at the top of a fire door, allowing the door to swing freely with little forced required to open it. However, the door closer will automatically close on a fire door should a fire alarm sound, meaning the door then acts as a barrier to stop a fire from spreading throughout a building. It is also worth considering the benefits of soft-motion closing. This functionality closes doors in a progressive and controlled manner, following their release from hold- open or free-swing modes. This helps minimise the risk of injury for users, while also limiting damage to the doorset. Soft-motion closing can help deliver a longer-lasting solution, extending the lifespan of the doorset, while also lowering whole lifecycle costs.


A smart specification


It should go without saying that the holding power and the manual release force of the door closer must be correct for the size of door that the mechanisms are fitted to. It is, therefore, recommended that specifiers approach an experienced and knowledgeable door closer partner that can advise and assist with this.


Furthermore, many electro- mechanical door closers are difficult and time-consuming to change between hold-open and free-swing modes, typically requiring additional parts to do this. Their fixed power set-up – generally EN 4 – means that for larger door


leaf sizes, these can be very difficult for less able users to open. However, some of the latest door closers available on the market provide the flexibility to change between hold-open and free-swing on-site in a matter of seconds, while offering variable power of between EN 3 – 6. This allows the closing strength to be tailored to the door width while ensuring the lowest possible opening forces are retained, regardless of door size.
