All door pair sizes are "overall" for the pair, they are not for each door leaf, we cannot stress highly enough that the sizes are for both halfs.
Our standard range of interior double doors are mainly available in the 1981x1168x40mm and some are also available in a range of sizes including, 1981x1220x40mm, 1981x1372x40mm and 1981x1524x40mm overall sizes including where they are machine rebated at the point where they meet in the middle.
When considering double doors you do not have to be restricted to the sizes shown above, it is entirely practical to get any two standard sizes of doors and place them together to form a pair, in doing this you then have the choice of (explained in next para) adding a rebate, machining a rebate or just allowing the doors to meet in the middle with a minimum amount of space.
This is when two doors the two doors overlap where the meeting rails of the doors join when closed, machining a rebate is when half the "thickness" of the door is channelled out (for want of a better description) to allow the doors to interlock by 12mm, you can also choose to add the rebate if you have the correct space within your frame where the doors will be fitted, lastly you can get a "pairmaker" from our Joinery section within this site and add this to the doors where they will meet in the middle, the interior pairmaker adds 10mm to the width of the doors and 15mm for the external door pairs.
Machining a rebate reduces the overall width of the door by 12mm but adding a rebate adds 12mm to the overall width of two doors whereas the pairmaker component will add 10mm 0r 15mm for external door pairs.
Please do not arrange any tradesman until the goods have arrived, been checked over for damages and are suitable for installation as you intended, courier delays due to illness, traffic issues or product damages can also impact on your arrangements. Wood products will have a naturally occurring grain, this will vary regardless of veneer type, this is the beauty of wood. We cannot be held liable for any consequential costs should you arrange an early installation or whether the courier is delayed and lastly if the grain is wavy / straight and not to your liking.
