Door Skin
Manufactured from 1.5 Zintec Steel, double skinned with interlocking seams reinforced vertically with interlocking channels and horizontally with tubes to prevent twisting. Spaces are filled with dense Rockwool.

Standard thickness is 45mm, but any other thickness is available on request.

Rockwool is used for Fire Rated Doors and are effective in reducing the "U" Value (thermal transmittance)



To achieve the Fire Rating the Door must be either Un-latched or Latched;

The door doesn't have any locking or latch, but must have a Heavy Duty Door closer.   The Door Closer will fail but by the time this has happened the door will have expanded within the frame and close off any gaps to prevent the spread of a fire.

If a door closer is not fitted then a mortice latch must be fitted to achieve the fire rating.   This latch could be anything from a standard Sashlock to Panic Hardware.

We stock and sell a full range of Locks, Panic Furniture, Door Closers, Key Code Locks, Door Stays, Monkey Tail Bolts, Shoot Bolts.
If there is a specified requirement for a certain manufacturer of hardware, we can implement these into the quotes and designs of the custom security doors.
