Roller Shutters

Description

The aluminum Roller Shutters that our company provides are the best solution if you desire both burglary protection and protection against bad weather.The high degree of protection against burglary is certified by the German Insurance Association.

Our roller shutters are very durable and offer a high degree of stability against the action of external factors and a long operating life.
Sun protection is at its highest because the light can be totally blocked when the roller shutters are completely closed.
There’s an increased level of insulation thanks to the polyurethane foam injected inside the slat. You can choose from several types of slats depending on the desired effect and the size of the application.

In sum, they offer perfect sun shading and protection against burglary, multiple operation possibilities, both manual or motorized and a wide range of colors, all of which are meant to satisfy the most demanding requirements.

Types of boxes used

Box size

 

1. VARIMAX Classic version

This is the classic box that houses the axis around which the Slats envelop and that is designed to be assembled outside.


 

 

 

 

 

Currently, types of boxes RV-137, RV-165, RV-205, are used.

Box size

 

 

 

 

 

2. PROTHERMA version

This box is assembled in the wall and when the shutters are being lifted, they are invisible.


3. VIVENDO version

It is a type of box with a roundly shape, in some cases better adapting to the style of your home


 

 

 

 

All of the above boxes can be used with all the range of VARIMAXX roller shutters, both the mini variant and the maxi variant, but also with the mini variant with the built-in insect net.

Choosing the box type, according to the Slat type, the axis type used and the height of the shutters is set by the following table:


Guides of the roller shutters:

Type of material: extruded aluminum comes with sealing gasket or brush, both on the inside and outside.

Guide colors: possibility to choose from a wide range of colors (in stock: white, dark brown, grey)

Maximum length: depending on the size of the shutters (but no bigger that 4 linear meters, for VARIMAXX mini and 3 linear meters for VARIMAXX maxi).

Guides used allow fixation of the shutters both on the level of the window frame and also on the level of the joiner (depending on the concrete conditions of assembly)

The usage of bicameral guides allows the “hiding” and concealing of the screw head therefore it will no longer be a spoiling element of the overall image of the shutters and doesn’t allow the moving elements of the shutters to get stuck in it.

The role of the gasket or sealing brush is to accomplish a better sealing, but also to secure an easier sliding of the Slats, due to the fact that it reduces friction between the Slats and the guide. Also the gasket or sealing brush attenuates noise produced by shutters.

Types of guide used:

1. VARIMAXX mini

 

 

 

 

 

2. VARIMAXX mini with built-in insect net

 

 

 

3. VARIMAXX maxi

 

In case of VIVENDO version, on the guide can be applied a rounding profile therefore changing its exterior aspect.

Blocking devices

One of the benefits of using the aluminum roller shutters is ensuring an additional protection.
Generally, any roller shutter of VARIMAXX range, in the standard version, may be blocked in the shut position. The blocking is carried out with the aid of the elastic slats fixing the roller shutter’s slats on the axle. When the roller is pushed up from the outside, the elastic slats “catch” the slats which cannot be pushed up. However, due to the fact that the height of the roller shutter is not always a multiple of a slat width, it is often possible that the roller shutter can be pushed up a width of a slat at the most. This can be bothersome so special protection devices are used.

There are many devices to completely block the roller shutter in the shut position and it can’t be unblocked to be pushed up only from the inside.
The simplest blocking device is the one with pins in the closing bar. This device uses two pins sliding at the closing bar level. When the blocking of the roller shutter is desired in the shut position, the two pins are pushed towards the sides, they slide and enter in the holes from the bottom of the guides. When the unblocking is desired, the two pins are pushed to the inside, the closing bar unblocks and the roller shutter can be pushed up.
The advantage of this system is that it is simple and so the process is extremely small.
The disadvantages of its use are that the operation of the roller shutter from the inside does not lead to the unblocking of the roller shutter (the unblocking, a separate operation, must be carried out before operating the roller shutter).

The disadvantages of this blocking system do not recommend it in the case of the roller shutters operated with and electric motor. In this case the pushing up of the motor can be easily controlled, the system not being blocked, and in this case the roller will be undoubtedly damaged.
A second protection system is the GARANT system.

This system uses a device located at the level of the
first Slat of the roller shutter. In the shut position of the roller shutter, the mobile elements of the blocking device enter at the level of the blocking elements inserted at the guides’ level and prevent its raising. When the axle is rotated (which is possible only from the inside), with the aid of the manual or electric operating device, the mobile elements of the blocking device draw back to the level of the first Slat and allow the roller shutter to be pushed up.

The advantage of this system is that it can be used in the manually operated version, as well as in the electrically operated version, without any problems.
The disadvantage is that it is a fairly complex system and its adjustment must be carried out carefully.

A third system is the SOMFY device, which can be used only with electric roller shutters or manual roller shutters with cranks (not with the roller shutters manually operated with bands). When the roller shutter reaches the lowest position, the axle is blocked and the device is a little strained. When the roller shutter is thrust back order to push it up, the blocking system is damaged and cannot be pushed up (as long as the axle is fixed). When the roller shutter is pushed up from the inside, thus the axle rotates, the device is unblocked and the roller shutter works normally.

The advantage of this system is that it is very simple and thus it can be adjusted easily and works flawlessly. The major disadvantage is that it cannot be used with the roller shutters manually operated with bands.

If the actuator mechanism is electric and an additional blocking system is used, the protection of the roller shutter may be increased by using centralized and programmable control systems.

Using such a control system, the owner of a residence can be sure that all the roller shutters may be closed using one button and, if desired, the roller shutters may be programmed to be closed and opened.

Operating system

The operating system is designed to ensure a quick operation with the smallest possible effort. The design of the operating system allows its adaptation to the roller shutters installed in boxes at the street front level, as well as to those with their own box.

According to the weight of the roller shutter, in order to ensure an easy operation, the driving system may be with band, with rack rail or with electric motor.
The electric operating system is far superior to all the others, as it allows a very easy and simple operation and, in addition, it may be integrated in complex operating systems.
Also, the operation of the electric system may be done only with a simple switch, as well as with a remote control or with a programmable system.
