.....Continued My Sealed Door.
ok here are the pics of the sealable door.
the latches are bolted on and work on the same principle as the hands of a clock, and can be turned full circle when the door is open, the stays are shaped like a door wedge, or a slice of cake, when the door is PULLED closed you turn the latches toward the stay and when it touches the stay it gets tighter as you keep turning it because the stay gets thicker and the door gets pulled really hard against the weather seals.
the 3 top latches turn clockwise to lock.
the bottom one turns anticlockwise to lock.
pic 1, shows the latch bolted through the huge handle attached to the door, you can see the nut and locking nut, this can be spun 360 degrees.
pic 2, shows the latch turned 90 degrees to the stay and has pulled the door tightly outward.
pic 3, shows the third latch and bottom latch in the closed position, you can see the wedge shape of the bottom stay.
pic 4, shows where i ripped the tape back to show you the door make up, 2 layers of 3/4 mdf and middle layer of 1/2" drywall all screwed together.
pic 5, shows the door closed and locked with a single bathroom lock from the inside.
pic 6, shows the door closed at the bottom and the floor plastic rising up behind to keep water spillages in, the floor will hold up to 1200 litres of spilled water.
pic 7, shows as above with door open.
pic 8, shows the latch quarter turned and ready to pull down in to the tight horizontal position, you can clearly see the wedge shape.
pic 9, shows the sealed visqueen floor plastic at the other end of the room.
pic 10, shows the door closed from the inside and the gap is clearly visible between the wall and door, there is a difference in the gap distance hence the need for weather seals.
pic 11, shows the door in the locked position, if you try and push the door it will not budge even a fraction of an inch as the pressure of the latches pulling on it are so great that the latches are bending.
all the components except the screws bolts etc, are made of timber and covered with aluminium tape.
this room is pitch black inside when the door is closed and the lights are off. it is totally sealed except for inlet and outlet ducts.
there is also an eerie silence due to the sound proofing.
