Most buyers looking for new garage gates for the Kaliningrad garage quickly are aware of the advantages of roller gate. Convenient and compact design, it can be installed in almost any opening. At the same time, the sectional gates need a slightly greater explanation and understanding, but they are still leading in sales in Europe and country, and for a long time. what is the reason?
Roller shutters can be installed in any garage, regardless of the shape of the doorway. Since there is no need to install an internal guide, the door is compactly placed above the opening, without taking space under the ceiling. At the same time, garage sectional gates require the internal space for horizontal guides, which, in fact, is a constructive difference between these two types of gates. So, both types are opened vertically and can be installed in garages of any form, so why not consider installing the rollete gate?
Design
The design of the rivet gate has only one horizon, so you can choose only by the color of the coating. There are very subtle differences as the lamella used. For doors made of steel lamelles, the difference is even less. Sectional gates are available in various drawings of the panels (three horizontal and phylene) and can be painted in almost any color 200ral or covered with laminate under a tree.
Color
The choice of paint and finishes for most roller shutters is very good, but limited. Sectional gates are available in all colors of RAL or BS, with some exceptions (for example, exotic colors, such as light green). The variety of decoration for wooden gate wood is even more limited, but there are fashionable modern metal finishes.
Material
Rolling gates are made of "cold" single -layer or two -layer aluminum lamellas with insulation. The cross-sectional doors can be made of single and two-layer steel panels, fiberglass panels (Hormann Alr Vitraplan), wood (Hormann LTH) and even aluminum.
Insulation
Roller shutters made of aluminum lamellas filled with double foam, usually about 19 mm thick, provide sufficient thermal insulation and sound insulation, and since there are always small gaps in the door leaf, there is no accurate value of U in the published data. Connection of metal plates.
Most manufacturers make transverse doors with foam sections with a thickness of 40-45 mm, with rubber seals along the edges of each sash (standard doors usually consist of four paintings and the upper edge. From below and on the sides there are rubber seals, and on the sides).
If the garage opening has the correct shape and has a rectangular shape, the tested value of “U” can be used to achieve a very high level of isolation.
Companies such as Hormann offer even better and improved insulating seals for thermal cards. This allows you to add insulation and sound insulation where it is necessary (in most of country).
The size
The maximum width of the roller shutters is about 5.2 meters, and the height is about 3 meters. The transverse crossing doors from steel panels with double foam can have a width of up to 7.5 m and a height of 3 or 5 m (for industrial gates). The transverse gates with such huge sizes are very easily controlled by hand, and the roller shutters have a limited manual width adjustment (about 3 meters). Therefore, everything that goes beyond these sizes is controlled by an electric drive.
Automation
Rolled gates can be manually controlled using a spring. Otherwise, it is controlled by an automatic or installed engine with a tubular drive inside to rotate the cylinder using a toothed or chain mechanism.
Sectional gates are always made mainly as a manual gate, so they have torsion or spring mechanisms. It is thanks to him that the rise and descent of the gate is very smooth. The spring is on the side of the gate, front or back of the gate. Some models are located above the gate, but at the same time along the entire length of the guide. The choice of the position of the spring and the type of rail depends on the jumper, the height of the ceiling or the length of the garage.
