What is the size of the doors and windows of the building? Like M1021 or C1520 height is from the amount of the above? What about the above beams?
M1021 said the rear frame set aside the size of the doors and windows hole 1000 * 2100, the installation of doors and windows, the hole and the door frame between the frame there is a thickness of about 1cm gray strip, when used in the wall plaster embedded window frame The The actual door frame size is 980 * 2090 doors and windows height does not include the beam height. Therefore, with or without beams, does not affect the size of doors and windows. Look at the map to understand
After the installation of doors and windows, M1021--1030 wide, 2130 high. C1520--1530 wide, 2030 high. From the bottom of the beam down the amount.
This is the size of the hole, not too beam
