Calculation of the amount of curtains
Apr 02,2022 / Industry News / Author: admin
After measuring the size of the window, add 15 cm to each side of the width of the casement curtain. This is the usual position for the installation of curtain hooks, and the size of twice the actual width is reserved for pleating, and some patterns are more effective if calculated by 2.5 times. Okay. The hem of the curtain is 1-2 cm away from the floor, so as not to mop the floor unsanitary, and this will make the room appear higher. If it is a half curtain, the hem of the curtain can be placed 20-30 cm below the windowsill.
You can remember the following formula: (window width + 0.15 × 2) × 2 = finished curtain width
Finished curtain width / fabric width × curtain height = fabric required for curtains
Curtain head calculation formula: Curtain head width × 3 times pleats / cloth width = number of widths
The number of frames × (the height of the curtain head + the margin) = the number of meters of fabric required
Roman shades are divided into inner Roman shades and outer Roman shades. The outer Roman curtain can cover the outer frame of the window, and the inner Roman curtain must be measured accurately, measuring the upper, middle and lower dimensions. A single width of Roman blinds is within 1.5 meters, so you only need to consider the length when calculating, just use one piece of fabric.
Apply the formula: 1 piece × (window height + Burmese edge) = required fabric meters
Roman blinds need to wear aluminum strips on the lining, and the length of the lining should be added with the fabric required for pleating.
Application formula: curtain height + 4 cm (the amount of fabric used for each pleat) × number of pleats = the number of meters of fabric required for the lining
Step 5: Curtain Rods and Slides
Accessories determine the hanging effect and convenience of curtains, so you must be more careful when choosing.
Curtain rods and slides are made of plastic, wood, aluminum alloy, iron, stainless steel and pure zinc alloy. The surface treatment of aluminum alloy materials should be electrophoretic paint or oxidation. The difference between it and spray paint is that the surface of spray paint will be uneven when viewed by light, and the hand feel is very astringent, while the surface of electrophoretic paint and oxidized products has a bright and uniform surface color and smooth feel. Silky soft. The surface treatment of iron includes ordinary spray painting and electroplating, but if the treatment is not good, it is easy to fall off the paint. It is common to use two pipes for splicing, and the sliding performance is also poor, but the load-bearing capacity of steel cannot be replaced by other materials. When choosing, you must look at the wall thickness of the pole. The thinner the wall, the smaller the bearing capacity of the pole, and the easier it is to cause accidents in the future. You can remove the decorative head yourself to check the inner wall.
Pole installation is sometimes difficult because of the walls. Pay more attention to the design of the bracket, the contact surface between the bracket and the wall should be large, and it will be stable when hanging.
According to its shape, the slide rail can be divided into: straight rail, curved rail, telescopic rail, etc., mainly used for windows with curtain boxes. The most commonly used straight rails are: heavy duty rails, plastic nano rails, and low noise rails. Aluminum alloy curtain track has high strength, good hardness and long service life.
The use of the telescopic rail is very convenient, and the scale can be adjusted arbitrarily, but when selecting, the focus should be on the handling of the telescopic interface, because the interface determines the service life of the window rail. If the interface is not handled well, the pulley will be worn during use, which will affect the pull-off. The curved rail is suitable for the use of various arc, octagonal and irregular windowsills. The thickness of the bending rail material determines the bending angle and load-bearing size.
