Rollets on windows can perform decorative and protective functions. Dense and strong lamels protect rooms from unauthorized penetration outside, and textile products form individual design of internal space. Fabric rollets protect furniture from negative impact of ultra-violet radiation.
Producers of rolletny systems implement two types of these designs. They differ with visual execution, utilization properties and properties, assignment. Decorative and protective rollets have additional classifications.
Safety in priority: all types of external systems
Protective rollets have functionality of classical metal grids. But they do not spoil exterior of facade, do not close the overview. Window rollets can constantly be in open position, but in need of them it is possible to transfer to the closed state in several minutes. When choosing street systems it is necessary to be guided on:
- Materials — polymers, aluminum, natural wood. Strong metal lamels which easily resist to corrosion for long years enjoy the greatest popularity.
- Technology of management. Several methods of opening and closing of lamels are provided. The tape inertial way provides hand operation rollets which weight does not exceed 15 kg. It is suitable option for small window openings. Cord vorotkovy the method assumes opening of systems which weight reaches 80 kg. In such design surely there is special handle.
It is possible to meet protective rollets with the spring inertia drive of management more often. This mechanism of turning easily influences dimensional systems weighing over 100 kg. One more option of management — automatic. For lowering and raising of lamels use the electric drive. Such designs are considered as the most progressive — they can be controlled from the console or according to the schedule if it is provided in model. Quite often owners of owner-occupied dwellings and country cottages with protective rollets choose start and stop on the programmed timer.
Decorative rollets: advantages and classification
These window designs are placed in rooms and perform esthetic function. They represent textile rectangular cloths which are fixed on cylinder in upper part of the block. In the unrolled state the rollet in whole or in part blocks penetration of light into the room. Similar systems differ from traditional curtains and have the following advantages:
- special impregnations protect surface from moisture, temperature jumps and sunshine;
- material of production has antistatic effect;
- brightness of color or the drawing, form remain throughout long life cycle of designs.
Textile rollets can fasten on each shutter or close all aperture completely. In the lower part of each system the making heavier elements are located to prevent spontaneous turning of cloth. For arrangement of dormer-windows side guides are used.
Rollets make of natural cotton, flax, smooth and velvety materials. Opaque and brilliant products from transparent, translucent fabrics are popular. Quite often rollets decorate with embroidery, prints, original images, decorate fringe and tape.
Depending on design of the mechanism they are separated into opened and closed. Products with nothing protected by wave on which the cloth is easily wound belong to the first group. And the closed mechanism provides its placement in special box. Lower making heavier the punk fastens to guides. This basis of design allows to place rollet most close to glass and to completely block receipt of sunlight if in it there is requirement. On the level of protection against ultraviolet the decorative designs are divided into four groups:
- "dimnut" — pass luminous flux, eliminate infrared beams, are suitable for inhabited and industrial premises;
- "blackout" — completely impenetrable, are ideal when using in bedrooms, rooms with the home theater;
- "day-night" — two-layer modifications, consist of wide strips of different degree of transparency, provide continuous adjustment of level of illumination in the room;
- transparent — easily scatter the sunlight arriving from the street, are combined with traditional curtains, portieres, perform especially decorative function.
When choosing rollets from textile materials it is also necessary to pay attention to way of management. In design the special chain cord can be provided. It is fixed on block cylinder from any party and activates the mechanism of turning, deployment of cloth for only a few seconds. The spring holder who acts as fixer is less often used. It enshrines bottom rail in certain provision between window fillets. At release of fixer the roll is taken up automatically.
The third and most progressive option — management of rollets by means of the built-in electric motor. Lowering and rise is carried out by means of the remote controller, the light sensor, on the programmed timer. Each user chooses convenient option independently.
Before purchase of rolletny systems of protective or decorative type it is necessary to execute measurements of windows or doors depending on where installation is planned. Mounting is carried out in or outside of the room. The combined installation which provides making of special dredging in upper part of window opening is possible. This option of mounting is planned for building blueprint stages as works are coming labor-consuming. The combined method is relevant for those who do not want to spoil esthetic appeal of facade, interior design, but is going to operate easily internal and external lamels, in turn opening shutters of windows. Installation works are performed by professionals after survey of object, evaluation of the work and removal of measurements. Often lamels are made individually for non-standard window systems.
