Due to this technology, the installation process takes a minimum of time, and the estimated cost of construction work is reduced.
Modular (element) glazing
There are many options in terms of size and architectural features.For each building, you need to select an individual option, taking into account the style, design features of the structure and the wishes of the owner. If you do not have enough experience to select an aluminum structure, seek professional advice.

They are made of alloys AD31T1, AD31T1 (25), AD31T1 (22), 6060T66 and 6060T6, technical parameters meet the provisions of GOST 22233-2001.
In many operational characteristics, the structures have no equal among the previously used building materials.
The aluminum frame is light, strong and durable
In design and construction buildings architects and designers are increasingly guided by the principle of "more light"
To fill the frame structure of stained-glass glazing, either glass or double-glazed windows is used
The use of special insulating profiles in the production of the frame can significantly improve the heat-saving properties
But there is one very significant drawback - high cost. Quality and performance come at a price.
Translucent structures made of aluminum profiles are quite expensive
Before considering the process of assembling structures, you need to study the special technical names of individual elements. There are quite a few of them, but you need to remember everything.
It is made by extrusion, it has different indicators in thickness, length and width. It is used as a main or additional bearing element.
The opening part of the window, the thickness depends on the number of glasses in the glass unit.
It is inserted into a footprint on a profile.
Metal plates with holes through which the structure is anchored to surfaces.
Some manufacturers complete their products with additional additional parts, the name and purpose are indicated in the instructions.

Values for physical strength, performance parameters and limit deviations of linear dimensions are prescribed by the Eurasian Council for Standardization, Metrology and Certification (EASC).
For window units, various ways of opening the sash are allowed.
Windows with different ways of opening
It is mandatory to use heat-saving profiles in heated rooms.
In order to increase the stability of the structure, the leaf area is ≤ 2.5 m2, and the weight together with the glass unit is ≤ 100 kg. The maximum dimensions of the doors are 210 cm in height and 120 cm in width.
Profile door leaves cannot be higher than 210 mm and wider than 90 cm.If large structures are required, then separate calculations must be performed for them for each loaded unit, including hinges and other additional elements. Resistance to constant static loads of the leaf plane ≥ 1200 N, bearing capacity in the corners ≥ 400 N.
All structures must have special holes for drainage of rainwater, a system for draining the internal cavities of glass units.At the same time, the elements of natural ventilation and water drainage should not have a negative impact on the heat saving indicators.
The design should provide for emergency emergency opening from the outside in case of emergency.
Aluminum alloys used for the manufacture of profiles, in terms of chemical composition and physical characteristics, must comply with the provisions of the current GOST 22233.

Thermal insulation inserts are made of polyamide in accordance with GOST 31014, to reduce thermal conductivity, the air chambers of the profiles can be filled with foamed polystyrene of various brands, these are the highest quality and expensive products. The connection of thermal insulators and seals is reliable and guarantees tightness for at least ten years of operation.
The durability of the profiles for the most loaded unit must ensure more than 40 years of use, and all component parts must meet the same criterion. All elements in direct contact with aluminum have an anodic oxide coating. For static load, structures must hold at least 500 N, for a torque of ≥ 25 N / m.
Aluminum translucent structures from a profile are the most expensive elements at present. We strongly advise against designing, assembling and installing them yourself if you do not have experience in calculating structural elements. Errors lead to the destruction of products, and this is not only a waste of time and money, but also the risk of injury.
The assembly of structures must be done in strict accordance with the design documentation, which indicates not only the dimensions, but also the technical characteristics of the elements. If you can independently calculate the loads in each of them, taking into account the peculiarities of the geometry, dimensions, installation location, wind and snow loads and other factors that exert efforts, then do the documentation without the help of professionals.
Important. Do not rush to cut the profiles according to these dimensions, check the accuracy of measurements several times. Remember that you will never be able to lengthen a part that is too short; you will have to throw it away. And this has a very negative effect on the final cost of products.
How to assemble a facade system?
Attach crackers to the facade profile according to the specified dimensions.
Prepare the template in advance, using it you need to fix all the elements on one side. For the template, saw off a piece of the profile up to one centimeter long with a grinder. Fastening is performed with strong self-tapping screws for metal, the size of the screws must be calculated or indicated in the documentation for the assembly of the structure.
Remove the protective plastic film from the place where the crackers are attached. Install the template on the profile at a calculated distance from the end, insert a cracker into it.
Important. If, during the installation of the facade system, the finished floor is not yet ready, then lift the cracker to its mark (zero level). The bottom of the vertical rack will be filled with concrete, the finished floor will rely on it, the biscuit should be on the same horizontal line with the finish coating.
The same must be foreseen with the ceiling. If it is not ready yet, then fix the biscuit below. How much depends on the specific design of the ceiling.
Insert the cracker into the template and drill four holes. Practitioners recommend using hemispherical self-tapping screws, they can withstand increased forces.
Press washers are inferior to them in these indicators. Tighten the screws without undue zeal, do not turn the threads. If such a nuisance happens, screw a screw of a slightly larger diameter into the same place. If the glass unit is double or triple, then it is safer to fasten the crackers with bolts and nuts. Make sure that the cracker is tightly pressed, check the reliability of fixation.

Step 3. After completing attachment of crabs on opposite profiles, be sure to check their position. Place two elements opposite each other, the edges of the crackers should be in one line. This is extremely important, otherwise there will be no 90 ° in the corners, it will be impossible to insert double-glazed windows.
Crackers should be at the same level
Attach anchoring heels to the special inserts, often the same rusks are used as inserts, only long.
Crackers for mounting heels
Responsible manufacturers supply them in a set. If not, you will have to do it yourself, prepare the plates and cut the threads in the end cavities of the crackers. The length of the heel crusts is approximately 6-8 centimeters. Attach the metal plate (heel) with anchors to a long cracker, then it is inserted into the hollow honor of the profile.
Screw on the plate
The plate is longer than the profile and has two additional holes with which the stand is attached to the floor and ceiling. Two embedded heels are attached at the top, and two at the bottom of the structure.
Embedded, 4 pieces
Step 5. Proceed with the installation of the ledgers. Crossbars are inserted into crackers, on the inner side surfaces of which there are special mounting slots for self-tapping screws.
In order for them to hold, attach them with self-tapping screws. To make the holes on the ledgers coincide with the landing nests, take measurements with a caliper. Find out the height of the seats and at the same distance drill Ø5 mm holes in the ledgers.
Marking and drilling holes
Practical advice. When drilling holes in aluminum profiles, take care that chips do not scratch the paint.
Timely clean the drill from accumulated chips. Aluminum alloys have an unpleasant property - they constantly clog the grooves of the drill, it does not work well and overheats.
Step 6. Insert the insulating glass seals into the grooves of the profiles. They have different heights depending on the thickness of the glass units.
Seals can be of different thicknesses
Rubber the ledgers with a seal margin of about five millimeters. This is necessary so that during thermal expansion, the seal constantly adheres tightly to the surfaces. Then, during final assembly, the protruding tip is compressed and forcibly sits in place in the groove.
Step 7. After preparing all the elements, assemble the structure into a single whole.
Insert the crossbars in turn into the vertical posts, they should fit into the screwed crackers. Fix the elements with self-tapping screws into the drilled holes. We recommend using countersunk self-tapping screws. They hold securely, and in case of minor errors they will not interfere with the insertion of the glass unit.
Connecting the elements
So that the outside aluminum does not touch the inside and heat is not lost , install a thermal bridge (thermal insert). It is installed in special mounting grooves of profiles, grooves are located in the middle of the elements. Carefully put the thermal bridge, make sure that it lies in place along its entire length.

Before starting work on glazing facades, you need to choose the optimal one for each case option. Today there are several types, each with its own characteristics.
Warm and cold. If the interior is heated, then in order to save costs for maintaining a favorable temperature, you need to choose a warm version of the facade glazing made of aluminum profiles.
Warm glazing has at least double-glazed windows; special profiles with several air chambers inside are used to create the structure.The cost is quite expensive.
Types of profiles
Cold will cost much less, the weight of the structure is insignificant, cheap single-chamber profiles can be used for installation. In addition to a small number of chambers, such profiles have thin walls - a smaller amount of expensive aluminum alloy is used for manufacturing. As a result, the selling price is much lower.
Frameless and frame structures. For frameless profiles are not needed, there is a different installation technology. And to create frame, aluminum profiles and additional elements are used. Frame frames can have several types:
Post-transom consist of vertical bearing racks and horizontal transoms.
The parameters of the metal profiles are selected depending on the size of the structure and the characteristics of the glass units. We described above how such structures are assembled.

The applied solution of the bracket provides a wide 3D-range of adjustment of the position of the fixed post, provides a minimum gap between the facade and the load-bearing ceiling.
They are made according to the sketches of consumers at specialized enterprises and are delivered ready-made. The individual modules are assembled on site. Due to this technology, installation time is reduced and the risks of incorrect assembly are eliminated. Unfortunately, the cost of the construction increases significantly.
Modular glazing system
Construction of modular elementary glazing unit
All fasteners are located inside the structure and are invisible from the outside. They have improved design characteristics, but there are restrictions on the height of buildings. The structures do not have a sufficient safety factor, the weight of the structure is limited.

Semi-structural. They surpass structural ones in strength, have additional reinforcing elements.
Semi-structural facades are also created using structural glazing, but there are a number of differences from fully structural facades
Organization of the transition from the inclined part to the vertical in the semi-structural type of glazing
Important. Installation of the facade system from aluminum profiles is carried out without double-glazed windows. If there are window sashes, they are dismantled.
Step 1. Measure the dimensions of the opening in the wall, check if they correspond to the parameters of the facade system.
If necessary, increase or decrease the openings, the optimal distance between walls and structural elements is 1-2 cm.
Step 2. Carefully lift the assembled structure and install it in place. When lifting, apply force evenly, work must be performed by at least two people. Align the structure strictly vertically in level, fix its position with wedges.
Raising the structure
Step 3. Drill holes for anchors around the perimeter of the profiles, insert them into place and secure. Lock your heels at the top and bottom of the structure.
Step 4. Blow out the cracks between the aluminum structure and the opening in the wall with foam.
Moisten surfaces thoroughly before foaming. Moisture not only significantly increases the adhesion of materials, but also accelerates the curing time of the foam.
Step 5. After hardening, cut off the protruding foam, smooth the surfaces with plaster.
Carefully insert the insulating glass units, replace the glazing beads.
Installation of aluminum structures
This completes the installation of the structure, you can proceed to the finishing of the premises. If the floors are incomplete, do your best to ensure that the bottom ledger has a stop along its entire length. This greatly strengthens the structure and increases operational safety. If during the installation of double-glazed windows, swaying was found, be sure to find the cause and eliminate it.
It is strictly forbidden to install double-glazed windows in fragile structures.
