Superfold 4000 & 5000 insulated folding doors have been specially designed and tested to meet the requirements of high security installations whilst maintaining the high aesthetic appearance and thermal properties of our high quality range of insulated folding doors.
The door has been independently tested by the Loss Prevention Council to LPS1175 (Specification for testing and classifying the burglary resistance of building components, strongpoints and security) and has received approval to grades 4 and 5 – the first folding door to be approved. This approval confirms that the Superfold 4000 doorset will survive an experienced attempt at a forced entry using portable tools while the Superfold 5000 will survive professional attempts at forced entry with a combination of mechanical and mains powered tools as specified in the Standard.
