Most of the time, any project of a building is the first and only communication between the observer and the architect. Determining the geometry of the envelope of the building, conceiving the project and identifying the technical performance criteria are the architect’s job. While the building systems designer’s job is to define the conceptual design of the architect in terms of a structure of components that stabilizes a continueus building systems throughout the whole life cycle of the building.

Architectural design system is making the best possible mix of the function, geometry and the structure of aluminium extrusons, plastics, sealants, gaskets and whole other elements in order for achieving the performance measure and norms.Design concerns extend from the aesthetics and performance requirements of the architect to the production and installation requirements envisioned by the system designer.

An accurate Architectural design is to be flexible enough to be applied in all elements of the building by means of aesthetic and technical concerns such as heat transfer, insulation, acoustics etc. and at the same time applicable to produce and sustain. An architect must determine the most economical way in design strategy.

The building designers should take the regional differences in consideration. This results in using new systems in building design. 


A detailed design should be applied in order to develope all sections including the intersections and connections.

Architects, technicians and engineers are the basis of the Alumetal Building Systems. We use ACAD and Solid modeling softwares to resolve the projects. Customs softwares are also created by our experts in order to improve the company’s capacity.

Our company’s processes are secured with the ISO 9000 Quality Management System . Design process is tracked online so that it can be reported the current status of each piece of drawing file as well as the time spent so that the time planning schedule is controlled by the project design chief and the project manager. The transfer of shop drawings to the production drawings department and the transfer of production drawings to the CNC machines are realized through the internet and intranet networks.


Façade design with the help of developments in computer technology, have recently become more important in façade engineering. After the 90’s, façade design has been seen as a new department in architectural world. Today, this department is raising Ph.D and Master’s degrees with international (AAMA, BS, EN ) and local ( SNIP, GHOST, NF, DIN) norms and standards.

This department presents new design techniques and norms to R&D department, prototyping services and product development team in order to provide engineering consultancy services. The department is equipped with the most innovative technology such as 3D and 2D modeling and these designs is tested with Computational Fluid Dynamics (CFD) methods and other simulation programs including Virtual Wind Load, Dynamic Structural Calculations, Heat Flow Analysis, Condensation Analysis, Ventilation Pressure Analysis, Acoustical and Fire Analysis.

The methods currently used in testing such as wind tunnel simulations, does not give an accurate results in pressure integration over façade.

In our engineering department, CFD ( Computational Fluid Dynamics) is used to test Virtual Wind Tunnel Model and this method gives more accurate results than former tests in especially intricate external façade elements such as shading devices and externally ventilated double skin façades.

  • Static Modeling
  • Frame Integrity
  • Stress Analysis
  • Deflection Analysis
  • Anchor Analysis
  • Seismic Modeling
  • Impact Modeling
  • Fatigue (Cyclic) Simulation


Glass is an important element in façade design. It has become a specialized discipline in engineering because of its strength, thermal properties, light aspects and behavior under thermal stress. Glass has resulted in many problems in Curtain Wall systems. With the help of these virtual simulations including Finite Elements Analysis (FE) and Computational Flow Dynamic (CFD), these problems can be predicted and prevented. Also calculating the thermal stress accumulated in the spandrel glasses, verifying if adequate ventilation is provided in the space behind the spandrel glass is an important issue. As well as CFD modeling, we use the “Vitrage Decision” of French CEBTP.

Internal seals, sound reducing infill and position of glass and pvb layer used in Curtain Wall Systems are decided by our acoustics engineers working with our design team.

The drop securing function is an significant criterion which must be examined with Impact Tests according to the European Standard DIN, EN 12600. Besides, it can be tested in both laboratory and computer.

Lastly, we also use new generation fire simulation softwares in order to give a broad perception to the designer and prevent unnecessary expenses.

The creative use of advanced analytical tools and techniques allow the engineering department to achieve buildings that respond well to their climatic conditions. Thermal analysis applications include:

  • Convection and radiation, using advanced computational methods.
  • General heat transfer calculations, thermal bridges.
  • Moisture and condensation analyses, estimation of surface temperatures.
  • Calculation of U-Values for building construction parts.


To predict the performance of a double skin façade is not a trivial exercise.

Airflow Modeling Method in Computational Fluid Dynamics (CFD), that we use, plays an important role in determining the performance assessment of double skin systems. When we are utilizing surface condensations and heat transfer analysis, we take consideration the climate differences among the countries. In transient method, thermal analysis of the façade system or the interface of façades and buildings is made in two or three dimensions and in time dependent form.

The glazing infill panel, the frame, construction behind opaque areas are the functions in overall curtain wall thermal performance which are also calculated in relation to EN 10077-2.


Alumetal Building Systems, which operates under ISO 9000 Quality System, ISO 14000 Environmental System and ISO 18000 Health and Safety System, manufactures in its factory in İstanbul, Turkey. According to our experiences acquired within many years, a project’s most critical parts are façade fabrication and assembly.


In order to minimize the problems occurred in site while the assembly process, we, Alumetal, resolve all the obstacles in manufacturing process in the factory. We have the ability to produce the machinery, which is needed in an effective installation but cannot be found on the market, used in the special projects. Local manpower trained by our engineers in our company in İstanbul is always steady to be sent in any project around the globe. Besides, in any emergency, installers from İstanbul can be sent to the sites. We prepare a great quality plan depend upon analysis that determines the types, performance requirements and design details before starting any project. As well as a safety plan is prepared to analyze all the risks resulted from the specific conditions in the site.
