Using Lorient's indicative furnace, the fire resistance properties of building materials can be tested in accordance with BS 476-20 (method of test for determination of the fire resistance of elements of construction) or EN 1363-1 (fire resistance test standard).
Our indicative furnace has proven popular for many years, providing customers with real insight into their own products’ performance. Lorient can also perform comparative indicative tests and has recently made a live fire test available on-demand that shows the critical importance of intumescent seals. During the test, we burn the doors in our furnace side by side for 30 minutes, to see how long the fire doors perform effectively until failure. The footage explores the significant difference in fire resistance between a sealed FD30S and an unsealed door.

- FD30 fire door
- 44mm GDC Core
- 6mm Georgian Wired glass - Pyroshield 2

Post test fire door images
The image above shows a photo taken from the 'fire side' of the door leaves following a fire test. The door without seals (left) shows substantial damage to the edge of the vision panel and the door frame; especially at the door hardware.
An unsealed fire door typically fails in less than 15 minutes. This shocking comparison clearly highlights the importance of having a correctly specified, installed and maintained fire door for containing a fire and protecting the means of escape.
Fire doors are designed to save lives & protect property; but they need regular, stringent inspection & maintenance to ensure that they will perform as intended in the event of a fire.
If you're worried about the fire doors where you live or work, you must report them to whoever manages or owns the building. Get in touch with our expert Fire Door Inspection team to find out how we can help: firstname.lastname@example.org
