MATERIAL PROPERTIES

Aluminium

Window and door profiles have to be executed thermally separated.Light metal sheets and substructure:The sheet thickness has to be chosen according to structuralrequirements (windloads etc.).Foldings have to be done before surface treatment using thesmallest possible radius without cracking. The verge of the sheetsare to be coated as well. The cover metal sheet on the slab mustcarry the loads of the raised florr (connection raised floor/facade).

Before installation thehot-dip galvaned parts are to be checked for damages thoroughly.Damaged areas are to be cleaned, grease removed and coated twotimes using a high quality protective coating.

REQUIREMENTSChoice of profileThe profiles must be able to carry the loads safely. The moment ofinertia provided by the profile producer has to be considered whenchoosing the profiles.

Dewatering and Pressure relief(Aeration) The dewatering of the rebate and the prechamber has tobe executed in a way that the moisture is led to the outside. Thedewatering of the prechamber occurs at the deepest point of therebate. The pressure relief for the glass rebate must be inaccordance with the instructions of the glass manufacturer.WindowsizesThe minimum and maximum wingsizes as well as the maximumweight allowed by the profile producer must be respected.

Window sillIf not specified otherwise window sills have to be executed with aslope of 8 degrees using extruded profiles with the same alloy as forframe profiles. The window sill is to be fixed with the base profile.

The window sill is to be protected against lift-off and vibrations usingstainless steel straps. Endpoints and movement joints are to be fittedusing special parts.

Structural requirements

The contractor is solely responsible for the structural integrity of thefacade. The calculations, profiles & windloads if given in the tender,were calculated by an experienced local facade designer but areonly to be used as rough indication during the tender phase andhave to be rechecked and recalculated by the contractor during hisdesign works for the facade. Different results during the contractorsdesign phase do not allow the contractor to modify the unit prices ofthe contract.

Dimensions and material thickness are to be chosen by thecontractor. Loads must be safely transfered to the building. For iscalculations the contractor has to consider all romanianspecifications as well as DIN EN 1991-1-4 for wind loads.

Tolerances

All connections and fastenings have to designed and constructed ina way that tolerances in the structural concrete works do not causeproblems. At every anchorage point in the grid system a tolerance of +/- 25 mm in alldirections must be possible.Connection parts such as screws, bolts, nuts that come into contactwith aluminum must consist of chromenickelsteel (minimum qualityA4 with reduced copper content). All other connection parts are to behot-dip galvanized. All parts are to be secured against unwantedloosening.To prevent contact corrosion when mounting different metallic partsa separation layer of neutral material must be used.Corrosion prevention:The contact areas of building elements made out of light metal withbuilding parts made out of steel are to be protected againstcorrosion. In gaps where a sufficient passivity of the constructionmaterial cannot be achieved due to the lack of oxygen the metalconstruction materials have to be separated using appropriate pvcfoils.Further it has to be considered that corrosion can also occur atcontact areas with non metallic construction materials.

Movement joints & Thermal joints

Movement joints and thermal joints are to be calculated duringdesign works and to be executed airproof and waterproof.Connecting joints to the building are to be executed watertight. Thejoints have to move silently without making any noise.

Thermal insulation materials

Only non flammable thermal insulation in temperature-, weather-, rot-,mold proof quality is to be used. Intrusion of moisture must beprevented to ensure a good thermal insulation.

Heat InsulationThermal bridges are not allowed. Condensation must be preventedby appropriate design solutions.

Joint PermeabilityJoint permeability and resistance to heavy rain must be inaccordance with EN 12154 . If not specified otherwise resistanceaginast heavy rain up to 1200 Pa as well as a joint permeability <=0,2m3/hm Pa 2/3 is to be guaranteed.

Sound insulation

The requested sound insulation values have to be achieved andproven by the contractor. The requested construction soundinsulation described in building physics specifications (32dB).

Rain and Condensation protectionAll connections to the building are to be executed "steamtight" on theinside and "not steamtight" on the outside. Rebates and notches inwhich rain could enter or which could contain condensation watermust have a dewatering function to the outside.

Fire protectionThe execution has to be in acordance with the fire regulations.Powder CoatingLayer thickness 65 +/- 15 μm.Hot-dip GalvanizingLayer thickness 50 - 85 μm.

Ventilated FacadesVentilated claddings are to be executed in a way that penetrated water can drain to the outside and does not wet the thermal insulation. The ventilation must be minimum 4 cm in average.
