Box Opening

Some manufacturers offer as a standard width of 550 mm with a height of 1900 mm. and consider the standard width of 900 mm. The thickness of the boxes varies from 15 mm to 40 mm. All this is very important when calculating the size of the opening. To calculate the opening obbem need to know: the width and desired height of the door polotnatolschinu korobokshirinu korobokshirinu nalichnikovnalichie wooden door Let's say you need the door leaf 2000 * 800 mm. whose thickness is 25 mm box. To calculate the width of the opening should be leaf thickness to add boxes, which will be located on both sides of cloth, and allow the necessary clearance between the blade assembly and frame, door and wall unit (15 to 30 mm on each side). The formula is so 800 +25 +25 +15 +15 = 880 mm – this is the ideal width, which is suitable for 90% of the manufacturers of doors.

The height is calculated by analogy (with threshold = thickness of the box or the gap between the floor and the door = 10 to 30 mm) 2000 25 +10 +15 = 2050 for doors without threshold and 2000 +25 +25 +15 +15 = 2080 mm . door with a threshold – this is the ideal height of the opening which is suitable for 90% of the manufacturers of doors! And so, the canvases in size 2000 * 800 your opening: 2080 * 880 (+ – 10 mm). With a width of 600.700, 900 mm should be in proportion to narrow or enlarge the size. Together with height and width of the doorway there is its thickness. In the standard model homes thickness corresponds to 75 mm. Most manufacturers offer a way to market the box 75 mm in the preparation of the opening must take this into account. If the features do not allow the walls to withstand a given size (thickness less than or greater than 75 mm.) The question arises about the need to install the extender boxes (FLEXINVEST BANK, slope) and took a box along, if the wall is thinner than a box.
