Dortek have recently successfully tested our maximum sized fire doors in both directions of exposure. The door opening away from the furnace achieved an impressive 4 hours and 20 minutes, which is the maximum time span in fire testing regulations. The door opening into the furnace achieved 2 hours 48 minutes.
Most companies only test their doors in one opening direction but at Dortek we’re committed to testing our doors to meet the most stringent standards. Our fire doors are continuously tested to ensure they achieve the latest certification in each of the countries where they are installed. If you’d like more information on our range of fire doors please contact us at your local Dortek office or visit our fire doors page.
