The screen is made of special fabric applied to aluminum frames and rarely on wood frames in order to prevent the entry of annoying insects such as mosquitoes and flies, while allowing the space to be ventilated.
Today there are different types of screens:
- Fixed
- Opened (door)
- Vertical System
- Horizontal Movement
- Plisse Horizontal Movement without bottom guide
- Plisse Horizontal System with bottom guide
- Sliding
- Superposition.
i. Fixed Screen.
It consists of an aluminum frame in which you place the fabric screens. The frame is mounted either on the existing frame, or directly on the wall. The main disadvantage of fixed screens are just not open. Used as usual in places where the other so it would not be possible to open the screens.
ii. Opening Screen.
This screen type found mainly in the form of door consists of a frame in the shape of "Π" and the opening layer in which you place the fabric screens. The frame and panel made of aluminum. The screens of this type have a mechanism to restore the sheet so that the screen closes itself after opening.
iii. Vertical System Screen.
It is the most used type of screens. It consists of an aluminum shaft wrapped in fabric (fiberglass) of the screen. It has a return spring which assists in the correct winding of the fabric onto the shaft, and the flatness of the fabric when it is developed. You have spring and have a brake component that makes softer and controlled resetting of the screen. The screens "vertical motion" are used primarily in construction and hinged sliding rarer.
iv. Horizontal Movement Screen.
The screen has a similar function to that of the screen vertical movement, the difference is the movement of the axis of the screen on the bottom horizontal guide. The screens "horizontal movement" used mainly in construction and hinged sliding rarer.
v. Plisse screen Horizontal Movement without lower guide (with track).
The screen of this type are the latest results in the development process in the area of the screen. The frame is made of mainly aluminum except the lower portion,which is a drop-plastic device (the track). The two key features that make it stand out are:
1. The fabric (fiberglass) not wound on a shaft, but folded in a
zig-zag (plisse).
2. Although it is horizontal movement and should have lower driver as the classic grille pan, here the guide below basically does not exist, instead placing a plastic sticker a few millimeters thick on which the caterpillar moves.
The screen does not have a reset mechanism and remains in the position to leave. When fully developed held by a magnet, while the ground fabric in this situation has serrated form. Its main advantage is that the presence of minimal practical guide below allows for the opening, easy routing.
vi. Plisse screen Horizontal System with bottom guide.
The frame of the screen that is made of aluminum while the fabric is similar to the previous type screens. Because it has no bottom guide track and no construction restrictions (height> width). It can be single-ply or two-ply and each sheet can have much wider than the previous type. Finally, a sub-type of this sieve may be lined opening.
vii. Sliding screen.
The sliding screen consists of one or two aluminum frames, single-ply or two-ply respectively. The sheet or sheets (panels) are moved on a rail running gear (driver) and can be either recessed (to be within the wall), either external or internal to say on the outer side or the inner side the wall respectively. For the motion of each frame at the bottom of the mounted rollers (especially castors).
viii. Superposition Screen.
The laminated screen consists of two pages (frames) aluminum running parallel on two different rails rolling. For the motion of each frame at the bottom of the mounted rollers (especially castors).
