- Do not install the fire and smoke curtains ahead of time. Check if all the construction in the building is done before installing the curtains. It is to ensure that the curtains will not be damaged from the site work.
- Ensure that the rollers are fully horizontal so that the curtain fabric will not move and change its placement.
- Before manufacture, you must measure the height of the area where you want to put your curtain so that the curtain has the correct length and width.
- Make sure to put fire-resistant materials as a stopper on the space above the curtain. Ducts placed over the curtains must be fire-resistant or secured with dampers to prolong fire resistance.
- Equipment control systems must have extra supplies in case of emergency.
- Make sure that there aren’t so many gaps when you put the fire and smoke curtains. Manufacturers provide specifications on the maximum gaps of these fire barriers.

USING A FIRE AND SMOKE CURTAIN
You can activate a fire or smoke curtain in many ways. They remain retracted unless someone activates an alarm, a smoke sensor detects smoke or fire, or activated through a manual switch. Once triggered or switched on, fire and smoke curtains automatically descend into their operational location.
There are different styles of fire and smoke curtains, and their uses vary depending on their design. Regardless of the style, each of the curtains has the same way of operation.
Different Curtain Styles
- Elevator Smoke Curtains– they are used to block smoke from going in and out of the elevator doors. Since elevator shafts pull the air upwards to the roof of the building, this may cause the spread of the fire to other areas of the establishment.
- Draft Curtains– they are usually installed in manufacturing areas and warehouses. Buildings with open facilities and high ceilings should use this type of curtain. This curtain splits up airflow along the ceiling of a building. When using this, always remember to put it near an exhaust vent so that the travel of the smoke will slow down and be pushed outwards.
- Vertical Smoke Curtains– they are used to close and block the openings from doorways to large atriums. These curtains are installed on the ceiling above the opening. Once deployed, they divide the areas of the building into smaller spaces and hold in the smoke in individual rooms. It helps people to evacuate easily and firefighters to enter the building quickly.
- Perimeter Curtains– these curtains are ideal for escalators and open staircases. Perimeter curtains help slow the movement of the smoke and block an independent parameter.
