Blinds 百叶窗
- 拉绳是最早的系统了，一根转棒子，一根拉绳，这个是最便宜的
缺点：1是使用没有后两种 方便，拉绳会比较长，
- 一线通，比拉绳 的要高级好看一点，价格也高一点，这个其实和拉绳系统的 差不多的，
唯一一点就是：这个也有点二合一的，就是绳子做在棒子里的，同一个装置里的，方便一点
- 拉珠系统就要重点说说了，比较好的。我看着是比较有前途的，很多电动的百叶，就是同一个原理的。
但拉珠刚出来的时候，被有些厂家名声搞差了，有的窗帘店 谈到拉珠就会摇头的。主要是有几个问题，1，最早的时候这个拉珠配件耐磨性不好， 用的塑料都比较差的，没多久，配件就会磨掉了， 2是没有解决拉起来重的问题，窗帘一大，就拉不动了

In many homes and most offices, blinds are commonly used to give shade and privacy to the place. Unlike curtains, the amount of light that can be let in can be controlled if you have installed blinds on your windows. Many people feel that the problem with having blinds is the installation. This can be true, but these people neglect the fact that there are also other things that have to be considered before purchasing blinds.
I. Style
Blinds can come in different styles, the most popular of that are Venetian blinds. Decide on what style you want depending on the functionality and design of your windows.
1. Roller Shades These are made specially treated opaque or vinyl fabric wrapped around a dowel. They employ a spring or a beaded cord system to roll the fabric up or down. This is good if you want to have complete privacy and to protect the furniture from fading. The ends can be straight or shaped, and trimmings or contrasting braids can be added to the design.
2. Roman Shades These blinds have a cord woven thru the fabric that allows you to raise or lower the shade in an accordion pattern.
3. Venetian Blinds Also called horizontal blinds, they have horizontal panels made of wood or aluminum that can be adjusted to change the level of sunlight that can be allowed in the room. These are available in different widths ranging from 16 mm to 50 mm.
4. Pleated Shades These function similarly with Venetian blinds and have flat horizontal fabric panels. To let light enter from the top of the windows, you can have those that have top-down design.
5. Vertical Blinds They have vertical panels that can be adjusted to control the amount of light that enters. It can also be pulled to one side or both sides of the window to allow total natural illumination. Different types of fabric may be used in sizes from 89mm to 127mm.
6. Honeycomb Shades They are also known as cellular shades. These shades, thru layers of fabric capable of filtering light, can let light in and keep the heat or cold outside, thus giving the room insulation to save on your energy bills.
7. Woven Wood Shades These are usually made of bamboo, and blocks direct sunlight from coming into the room but allow some natural light to come in.
8. Mini Blinds Also known as macro, micro or aluminum blinds. These have one-inch or two-inch slats to adjust the amount of light that enters the room.
9. Shutters These have parallel slats, or louvers, that can be adjusted to change the level of privacy.
II. Measurement And Installation
The blinds should be unobstructed that when it is fully extended, it can still hang freely. For accurate measurements, it is recommended that you use a steel ruler. Cutting the Blinds is necessary to make the blinds fit the size of the windows. Before cutting the blinds, measure the desired width from one edge of the bracket to the other. The size of the winding mechanism should be deducted first before cutting the lath, the tube and the fabric to the correct size. To cut the tube, a mini hacksaw can be used, while for the fabric, it is recommended that you use a cutting knife or a sharp pair of scissors.
