Fire Doors

Grenfell Tower doors 'resisted fire for half the time expected'

Seems 3 fire door samples from Grenvil tower all failed in tests. They were supposed to be 30 minute doors but only lasted 15 min.

Having worked for a partitioning company and a interior refurbishment company I can claim to have  a little bit of knowledge about Fire Doors, although Im no expert.

The main points are

• Fire doors are notoriously difficult to get through a fire test and vision panels only exacerbate that.
• Once the fire door has passed the fire test and has a certificate, it then rely's on a few other things.
• Each fire door has to be manufactured in exactly the same way and using exactly the same materials.
• Once on site the door has to be installed in excatly the same way that it was when it passed the test.
• It has to be fitted in a frame which is exactly the same as the test. ie materials and construction.

This rarely happens

Further tests will be carried out on fire doors following the news that front doors to flats in Grenfell Tower burned in just 15 minutes, housing secretary Sajid Javid has said. 

However, he insisted that there is “no evidence that this is a systemic issue”

Due to the nature of how fire doors are tested and installed I believe there is a systemic issue.  There's no evidence because no one has looked for it.
