Blinds UNI-1 and UNI-2: Description of structures, their differences

External consumers hardly notice the difference between the two types of curtains, but any expert will explain that there are differences, and they are many.

Blinds UNI 2 are considered to be a universal mechanism, they are installed on almost all new windows. So the first difference - the ability to install any plastic profiles. But there are still some differences, take a closer look.

View the guide

First have flat guides for ESI-2 characterized by U-shaped rails. Because of this, the second system has a larger cassette.

To see the difference, the buyer will have to look at the assembly of roller blinds - the second box UNI more volume, the entire length of the substrate is placed in a centimeter thick for easy space inside U-rail.

The distance between the roll and the glass

UNI-1 are attached close to the glass, rolls in the open state in contact with the glass. If the window is often mist, wet cloth and sticks. This not only harms the fabric, but also can completely destroy the system - the fabric is glued, if you pull too hard, the product will fall.

The second model is devoid of such a drawback, it is attached to the frame and between the glass and the roll has at least a centimeter of space.

placement of the weighting agent

Bottom web weighting shutter placed in UNI-1 system, it is secured to the lower horizontally beadings. If the installer does not attach roller blinds perfectly horizontally on top, then the weighting will be placed out of alignment. Because of this lack of clearance from the bottom is formed, where sunlight penetrates.

The UNI-2 blind with a weighting agent always goes below the bead, so the gap is not possible.

Method window opening

Boxes for the two systems are different - one flat and one dimensional more. Overall box blinds UNI-2 limits the opening of the window, because the big boxes rests on the slope, which is why it is impossible to complete the opening of the window.

Flat box UNI-1 increases the opening of 11 degrees, but if the roller blinds installed on the balcony door, it is also not comfortable.

Mounting systems

UNI-1 attached to the glazing beads, but only if a minimum depth of 1.4 centimeters, and it is of rectangular shape. This leads to overlap of the glass bottom and side. The tape takes about four and a half centimeters from the top and side guides to two centimeters on each side. Thus, the window opening is substantially reduced.

If another form of bead, or its depth below 1.4 centimeters, it will not sustain the system. In this case, set UNI-2 by attaching it to the frame. Cassette opening and rails on the sides pass through the frame, and therefore does not cover the glass. In the clear window is the same as before the installation of blinds.

Advantages and disadvantages of UNI2 and UNI1

4. If the window properly designed, for example, the left side of the window a couple of millimeters long Right, when fastening the glazing bead to the horizontal bottom is formed a small opening, which will penetrate shine.

Advantages UNI-2

1. Universal product attached to any window to the top of the frame.
2. It does not close the window, because the guide and the cassette placed on the frame.
3. There is a gap between the curtain and the glass, condensation will not affect the status of the product.
