Learning how to install smoke seals on fire doors can save lives, as well as preventing extensive fire damage to your property. Smoke seals can be installed around fire doors – expanding when encountering heat to prevent the flames and toxic fumes from seeping through cracks around the door.

Fitting Smoke Seals

Fitting these smoke seals on your doors is a simple task, that can make a huge difference to safety for your employees, family and property. Below is a simple guide on how to install these important seals:

  • Sizing – it’s important that you purchase the correct sizing and measurements when investing in smoke seals. The wrong type of seal could mean that they will not be as effective on your doors as they should be.
  • Instructions – a silly suggestion, but many people try the DIY method when installing seals as it seems like a simple task. Make sure to read the instructions so you know exactly what you’re doing as a small mistake could create a big problem in the event of a fire.
  • Clean – make sure that the areas and surfaces where you are going to be installing the seals are clean. For the best fit, edges need to be free from dirt and grime.
  • All in one – wherever possible, apply the smoke seals in one, continuous strip. If this is not possible be sure to cut the seals to length before removing the tape from the self-adhesive backing strip.
  • Avoid stretching – Press the seal into place along the required edge, being careful not to stretch it too tight. This will lessen the effectiveness of the seal.
    Corners – ensure that the smoke seals fit into the corners of the door frame, this prevents as much smoke and fumes escaping as possible.
