Features and advantages of sectional garage doors (21 photos)

Sectional garage doors are a relatively young invention. Having appeared in Europe, this novelty quickly gained recognition and spread throughout the world. Now most people who want to install new garage doors choose the sectional option. Is it any wonder, because it is the “section” that meets many requirements and is perfectly suited to the modern pace of life.

What is a sectional door?

This term should be understood as a special kind of gate, the door of which does not consist of a single leaf, as in the usual swing models, but of several separate parts (sections). All these parts are reliably interconnected with special loops. Most often, 3 loops are installed on small models: one loop from each edge and in the middle. Oversized flaps require additional fasteners.

The scope of such devices is quite wide. They can often be found in private homes, garages, service stations, car washes, industrial buildings. In any of these options, sectional doors become a useful mechanism, convenient and easy to operate.

Structural features

Features and benefits of this type of gate are made possible thanks to the special structure.

Door leaf. As noted earlier, individual sections are fastened with loops, which provides a movable lamellas fastening. This allows the door leaf to move not only in a straight line, but also smoothly go under the ceiling or fold near the wall. Manufacturers offer a “cold” door and a “warm” one. Cold door sections are single layer. “Warm” lamellas are made two-layer with a layer of insulation in the middle. Such sectional doors for the garage are suitable for absolutely any type of room.

Suspensions and guides: rollers are located on the edges of each section of the door leaf. They allow the gates to move in one direction or another. The guides set the trajectory of the movement — special steel profiles fastened with suspensions. They are vertical and horizontal, in connection with this, the gates are divided into lifting and sliding.

Spring mechanisms. This part is necessary for balancing. The installation of torsion springs or tension springs allows you to open even a heavy large door leaf manually.

Classification and features

When choosing a sectional door, it is worth considering that manufacturers offer different models of this device. The differences are in the purpose and method of opening / closing.

According to their purpose, sectional doors can be garage and industrial.

• Garage models are suitable for installation in private homes and garages. They are small in size and do not require powerful wear-resistant fittings. You can choose this option for the opening of any width and height.
• Industrial types of sectional doors differ from garage doors in large dimensions, increased reliability, wear resistance. The main requirements that are imposed on such gates are the ability to work intensively even with a large flow of cars, making up to hundreds of openings and closings daily.

Models differ by type of opening:

• lifting (in this case, the door leaf sections rise upwards when opened);
• sectional sliding gates (in such models, the blade moves to the side).

The way of opening is also very important. He can be:

• mechanical (door leaf opens manually);
• automatic (automatic sectional doors operate using an electric drive);
• remote (remote control).

Due to this diversity, each customer will be able to choose a sectional door of the type that is ideal for performance.

Features and Benefits

Installation of sectional doors is a universal solution, as this design will be effective in almost all cases. This is facilitated by the numerous advantages of such a door leaf.

• Space saving. Unlike a hinged door, the “section” is capable of shifting to the side or rising to the ceiling. In this regard, she does not need additional space to open the wings. Sectional garage doors are suitable even for the most cramped rooms.
• Resistance to temperature extremes. A simple mechanism works without failures even at temperatures from -50 to +70 degrees. Thus, the installation of sectional doors is suitable for the region even with a harsh climate.
• Resistance to corrosion. The lamellas of the device are coated with a special composition that prevents the appearance of rust.
• High level of thermal insulation. When choosing “warm” slats, the door will reliably block heat loss and will not require additional insulation.
• Soundproofing. Due to the tightness of the structure (all cracks are eliminated), sounds from the street are drowned out.
• Possibility of manufacturing different sizes. The advantage of sectional doors is that they can even be installed on non-standard doorways (in industrial buildings, car washes, service stations).
• Maximum safety. Each sectional door device provides protection against cable breaks and locks that snap into place after closing.
• Simple repair. In case of damage to one or more sections of the door, they can be quickly and inexpensively replaced with new ones.
• A wide range of colors and textures. Such a choice of sectional doors makes the garage original and attractive.

Sectional drawbacks

Despite the large number of advantages in using sliding and lifting sectional doors, the design also has small disadvantages. You need to know about such nuances before installing a sectional door.

1. The high cost of the design and installation work. This can hardly be called a drawback, because the costs are offset by a long service life, convenience and aesthetics.
2. Proper maintenance. The key to a good gate operation depends on the regularity and correctness of service.

Special abilities

For those who decide to acquire such a device, professionals can advise additional features to improve comfort.

Sectional doors with a wicket door are an excellent opportunity not to open a large door leaf, but to pass through a small door. In everyday life, such trifles play a very important role, helping to save time, effort and energy.

In cases where you need to achieve natural lighting in the room, it is worth installing sectional garage doors with windows. Such models are called panoramic. They are often used in car dealerships and exhibition centers. Such lamellas are equipped with an aluminum profile, into which a translucent or completely transparent material is inserted. With the help of small windows, you can give the design a more attractive look.

Another convenient addition, as well as sectional doors with a door, will be a motion sensor. With this decision, the residents of the house or the employees of the enterprise will no longer have to open the doors - the automation for the sectional doors will do everything itself.

What to look for when buying

In order for the acquisition to be profitable and for a long time to properly serve its owner, when buying sectional gates (vertical and horizontal), you should pay maximum attention.

To begin with, we determine the features of the room and the intensity of operation - only on the basis of this we select the appropriate option and install it.

It is important to consider:

• door dimensions - for proper installation, measurements are taken from the doorway and the structure is made individually (this factor is especially important when buying lifting and sliding gates for a non-standard opening);
• the thickness of the lamellas - if the room is unheated (for example, a warehouse), then there is not much difference and you can save money, in the case of a heated room it is advisable to choose thick lamellas with insulation.

Before making a sectional door, many people ask whether it is worth ordering a professional installation of the device or whether you can make a sectional door with your own hands. According to reviews, the option of self-assembly is good for those who are familiar with the basics of construction or are willing to spend time and energy studying the issue. In all other cases, it is faster and more reliable to pay for the installation to specialists.

To summarize, we can agree with the statement: “section” is an extremely convenient modern device that can improve the quality of life. However, a brilliant result depends on the right choice and operation.
