  1. Please note that the maximum leaf width shown above is measured per door leaf.


The perimeter frame seals are self-adhesive seals mounted in the frame rebate, so are hidden when the door is closed.

The bottom seal (Type L) is an automatic door seal that lifts clear of the floor when the door is opened. The seal is fully mortised in a groove in the bottom edge of the door.

The bottom seal must close onto a smooth, flat and level surface in order to seal as intended.



The AD100 requires suitable latching in order for the frame seals to fully seal the gap between door leaf and frame.

Practically any standard door hardware can be used on the AD100, however the proposed hardware must be advised to Pacific Door Systems Ltd to assess the suitability, before manufacture.

Any penetrations through the leaf should be packed with acoustic materials (e.g. batts) wherever possible.

Concealed hinges are not an option on this doorset.

Recommended latching points are shown in the below diagram. Pair doorsets require a designated inactive leaf which is secured top and bottom.
