Our curtain wall are realized with aluminium sub-structure (mullion/transom and prefabricated unit cell system) and special spider system. They are EEC-certified to provide the highest levels of quality and performance and our production facilities are periodically inspected by agencies such as CSTB of  France an, SECO` of Belgium, IFT of Germany (with ZULASSUNG) and others.


Types of Curtain Wall

Technical Description of Royal Curtain Wall System

Field of application
The system is designed to create curtain wall for multi-storey buildings with load-bearing structures in reinforced concrete, steel or a combination of the two, such as hotels, public buildings, schools and so on.

Structure
The curtain wall system is manufactured completely in the factory and is assembled in large `cells` forming an aluminium profile structure with a special profile (patented as well as the overall system).
The horizontal and vertical sides of the cells are joined together by special telescopic couplings which absorb thermal expansion and minor seismic shocks and completely eliminate any cricking noise that these phenomena may produce. The absorption of differential structural movements (i.e. expansion and settling of the structure) up to values of 15 mm is achieved by means of telescopic couplings as well as gasket seals.

Cells Fabrication
The fabrication of the cells involves the followings phases:

  1. Aluminium profiles (mullions and transoms) blanking, drilling (as required) with the insertion of the relative gaskets.
  2. Insertion of the necessary accessories (e.g. trigger mechanism for glazing frame to-cell coupling).
  3. Assembly of the cell structure by means of stainless steel screws with perpendicular joining of mullions and transoms.
  4. Insertion of pressure-fitted containment sheeting and insulation material in the solid panels (as per project specifications).
  5. Insertion of cell-to frame support gaskets as well as perimeter sealant gaskets.
  6. Containment sheering sealing and insertion of insulation cut-to size panels.
  7. Preparation for the assembly of cells and frames (based on project requirement specifications) and subsequent packing.

Opening Systems
All the frames can be equipped with opening systems. If required, even after the installation, fixed frames can be changed into openings ones by simple adding a handle.
From the external view there are not differences between opening systems and fixed ones. The openings are generally outwards opening.

The outwards opening system is suitable for use with any type of internal blind or curtains. The mullions and transoms are flush so as to allow the connection of each modular axis directly to suspended ceilings and/or internal partition walls without using any special junctions.

Frame fabrication
There are minimal differences in the fabrication of frames destined for glazing elements as opposed to solid and/ or opening elements. Once the façade type has been defined, there is only one type of profile to be manufactured.
The fabrication steps to be carried out are as follows:

  1. Aluminium profile frames blanking, drilling and milling (as required) with the insertion of the relative gaskets to be interposed between glass and profile.
  2. Insertion of the necessary accessories.
  3. Insertion of glazing( single sheet  or double glazing0 or non –visual panels.
  4. Assembly of the frame by means of stainless steel screw and brackets (two for every angle)
  5. Optional installation in the non-visual panels (based on project requirement specification and in view to obtain a uniform appearance between glazing and `Spanderel`) of dark color pre-coated steel 8/10 thick containment sheeting.
  6. Solid panels internal containment sheeting sealing.
  7. Insertion of cell-to-frame internal support gaskets as well as frame perimeter sealant gaskets.
  8. Preparation for cell-to-frame assembly (based on project requirement specifications) and in order to obtain a uniform appearance between glazing and `Spanderel`) and packing.

Cell fixing system  
The anchoring of the cells to the building structure is designed to allow the adjustment of the curtain wall along the three orthogonal axes, and to accommodate the dissipation of vibrations, thermal excursion dilatation, seismic movements, as well as positive and negative flexures originating from accidental loads on the floor slabs. The installation of the cells is carried out by horizontal loops with the interposition of a junction core between each cell with the purpose of defining the alignment and ensuring water tightness on each floor.

Each cell can be installed independently from the adjacent cells on all sides and can also be adjusted for micrometer corrections of out-of-level errors in the concrete structure from floor to floor, and out -of-line errors in the cell row of the same floor.

Joint between cells
The interposed junction core between each cell, as referred to above, is sealed with specific elastic sealants after the installation of each horizontal loop. This system continuity between sub-structure elements, thus guaranteeing water and air tightness.
The core junction can also be installed vertically.

Main installation phases:Except for very few cases, this curtain wall system can be installed without scaffoldings or additional expenses to be borne by the building company.
The main installation phases are:

            1. Tracing out
            2. Placement of brackets, vertical plumbing, horizontal alignment and anchoring of brackets to the building floors using Halfen-type steel, bossed and welding
            3. Distribution of curtain wall cells, lifting and fixing of cells (by horizontal joints sealing
            4. Installation of handles (based on project specifications)
            5. Installation of metal sheet trimmings
            6. Internal and external perimeter sealing
            7. Final Client and Designer inspection.
