Internal door frame

[SLacKer]

I need to construct a partition stud wall to accomodate two 30" doors.

The doors will come together with no centre to the frame and I am wondering what the frame dimensions are for doors. Clearly I need 60" and then some for clearance either side and in the middle and then the door frame itself.

Anyone know what the door frame wood dimension is so I can work it out.

I always add an inch either side and at the top for the liner/casing.

Therefore opening in studwork would be 62" x 79" (or 79.5" to allow for 1/2" under the doors).

A few packers here and there and that should be fine.

Ovbiously differs if you are rebating both the doors where the meet in the centre - the 2 doors won't add up to 60"

If the doors aren't rebated allow 9mm on top of the 60" on the inside of the frame, 3mm either side of door and 3mm gap on the centre. this saves a lot of work when fitting the doors

The door lining timber is normally 28mm thick x 120mm wide (prepared sizes) being as its double doors you will have to make up your own door lining for the doors. Best to do housing joints at each corner and glue and screw the head to the stiles.

I'm not sure where you get 120 mm from, if it's a 4" stud which he hasn't stated 100mm + 12.5mm either side + 2.5mm of plaster either side is 130mm

The stud is 72mm x 47mm.

I plan to place a strip down the back of one of the doors where they meet. Thinking about it I will switch to mm in future so the door is 1921 x 762mm which gives a door width of 1524 + centre gap + (end gap * 2) + (frame width * 2). The height of the opening is currently 2007mm so will easily accomodate the doors.

Should the door frame be added after the finish plasterwork?

no, fit the door frame and plasterto it. make sure both legs eye through ( plumb 1 leg then look at an accute angle to make sure the other leg is in line) this will ensure the doors will be flush when closed

So if the doors are 1921 x 762mm I would need

762*2 = 1524 + 9 (3 either side and 3 centre) + 28*2 = 56 (Door frame thickness either side) = 1589 width to fit the doors and frame with a height of 1921 + 3 + 28 = 1952 + a gap for the bottom of the door to allow it to run over the carpet say 12mm (someone suggested 1/2 inch) so a height of 1964mm.

The doors are not rebated and will be flush with the wall on the opening side... it is for a wardrobe in my loft conversion.

[mackg]

yes that should do it, good luck

Done it . Some pics





Thanks for the help...
