High-rise buildings are a long-running global trend. The construction of multi-storey buildings made it possible to rethink architecture taking into account the requirements of the 21st century - the desire for the efficient use of urban space, as well as increasing the functionality of buildings. And we owe a lot to aluminum for the change in the appearance of cities. Profiles from this material are used for facade glazing and allow the construction of buildings with clear lines and unusual geometry.
Glass facades, reflecting the sky and the glare of the sun, make high-rise buildings weightless and graceful, emphasizing their individuality. There are many facade glazing technologies, however, among the most popular are post-transom and element (modular) ones.
Post-transom facade system
What does it look like?
The structure consists of an aluminum frame assembled from posts and crossbars. It is into these cells that double-glazed windows are inserted, which are reinforced with clamping strips. The joints are then closed with convex or flat decorative covers. The result is a facade that looks like a solid glass sheet from the outside, separated by seams.
The appearance of the facade largely depends on the width of the profiles visible from the outside. The well-known manufacturer of aluminum profile systems "ALUTECH" offers post-transom system
ALT F50, the external visible width of the profiles is 50, 60 mm, which provides visual lightness and maximum transparency of the structures.
Moreover, the manufacturer's assortment includes two modifications of the system, which allow the implementation of facades with invisible (structural glazing alt=" F50SG) or almost invisible (semi-structural glazing alt=" F50SSG) from the outside profiles.
What are the advantages of the system?
High rates of heat and sound insulation
How comfortable the microclimate will be in a building with a glass facade depends not only on the features of the system itself, but also on how thick the filling was installed.
In the alt=" A50 series, for example, it is permissible to use infills up to 68 mm thick, and in alt=" F50SG and alt=" F50SSG - up to 56 mm.
At the same time, a special EPDM foam seal is responsible for the optimal pressing force of the glass unit in the indicated series of ALUTECH profiles. It also increases the thermal insulation performance of structures (reduced heat transfer resistance Rпр of the system alt=" F50 –1.21 m²⋅ ° С / W, alt=" F50SG - 1.06 m²⋅ ° С / W).
A foamed thermal bridge, Mylar-based butyl rubber tape and an EPDM seal are responsible for maintaining the optimum noise level in the premises. In addition, the installation of sound-insulating infills up to 62 mm is permissible.
Long service life
The use of aluminum already in itself implies that the facade will last a long time: this metal copes well with any weather tests - temperature extremes, high humidity, exposure to direct sunlight.
However, experienced manufacturers know that even this durable material can be improved. For example, ALUTECH, for example, not only uses primary aluminum and its high-quality alloy, but additionally applies polymer paint according to the Qualicoat Seaside standard or anodized coating according to the Qualanod standard to the profiles, which ensure the resistance of structures to aggressive environments.
At the same time, all seals used in ALUTECH facade structures are made of high quality EPDM, supports are made of materials with a service life of at least 50 years, and hardware products are made of stainless steel.
Lots of design options
The main element that allows the implementation of various ideas of the architect with the post-transom glazing of the facade is decorative overlays. They can be of different shapes (rectangular, radius, volumetric), which makes it possible to create unique drawings right on the building. In addition, a wide palette of RAL colors is offered for painting profiles, as well as the ability to anodize them to emphasize the texture of the metal.
By the way, ALUTECH develops individual design solutions for specific architectural projects.
Elemental façade system (modular glazing)
What does it look like?
The need for modular glazing arose in connection with the proliferation of tower-type high-rise buildings. The difference between the element facade and the post-transom facade is that the object is supplied not with structural elements (posts, crossbars and double-glazed windows) disassembled, but a ready-made block assembled. Installation of such blocks is carried out without the use of scaffolding, from inside the room - the blocks are raised to the desired floor and mounted on pre-installed brackets. Among the manufacturers offering a system of profiles for modular glazing is ALUTECH. The assortment of the company includes a series
ALT EF65.
What are the advantages of the system?
High quality facade
Due to the fact that alt=EF65 modules for prefabricated glazing are manufactured in production under the supervision of a special technical department, facades on their basis are obtained with impressive quality and durability. Moreover, installation at a construction site with a minimum number of operations significantly reduces the influence of the human factor and, as a consequence, the possibility of marriage.
High thermal performance and tightness
In the profiles of the alt=EF65 series, multi-chamber polyamide thermal bridges with a thickness of 34 mm are used. In this case, the thermal insulation chamber of the impost is filled with foamed inserts made of a material with low thermal conductivity. High tightness of the structure is achieved through the use of a four-circuit seal set. All of the above allows you to significantly increase the thermophysical properties of the facade and achieve indicators of resistance to heat transfer of the structure.
Rpr ≧ 1.21 m² · ° C / W.
Reducing construction time
The cost of an element facade, as a rule, is higher than the traditional post-transom, but these costs are more than compensated for by savings on scaffolding and the timing of installation work. This facade technology is especially appreciated by investors who are interested in completing the construction of the facility as soon as possible and getting a building ready for use.
In general, element glazing of facades is perhaps one of the most productive building technologies of our time.
Thus, the market offers architects and designers many solutions for erecting buildings in the spirit of the times - large-scale, stylish and, of course, comfortable. Understanding the features of new building technologies and knowledge of leading manufacturers will not allow you to make mistakes when choosing the best solution for a specific project.
