TECHNICAL SPECIFICATIONS

STRUCTURE

Profiles will be: Type 70/78. Profile’s components will be of certified quality according to UNI EN ISO 9001 regulation. This certification will be presented to contract with “security cards of materials used” that certify no-toxic element. Components of these profiles will be RAU PVC 1406 type (DIN 7748), lacking in cadmium and that have these characteristics:
Density ca. 1,46 g/cm3 (DIN 53479)
Resilience min. 25 KJ/m2 (DIN 53453)
Linear coefficient thermal dilatation (20° C) a. 80×10-4K-1
Infiammability hardly inflamable

Profiles would have 5 insulation chambers, in a transversal way with thickness 3 mm. accommodation reinforcement chamber will have a dimension that will allow the insertion of reinforcement width 35 mm.

ALUMINIUM

External profiles will be realized through extrusion in aluminium EN AW 6060-T6, with thickness and dimensional tolerance certified by UNI EN 12012-2:2008 regulation. These profiles must be treated through an anodized finish or painted with RAL colours, metalized or wood effect. Alluminium profiles will be inserted with pressure to PVC profiles.

STATICS

Profiles selection and connection elements with reinforcement, that characterized windows, will be calculated in order to guarantee absorption of efforts derived from external factors (wind, mechanic actions, etc) internal (weight) and unloading of bearing structures that window is installed (Regulation: DIN 1055, part 4; DIN 1055 sheet 3; DIN 18056). Window doors must be calculated according to DIN 18056 regulation. Maximum arrow of bearing elements, in particular window-posts and transverses must not be more than 1/300 of length profile. For glasses the use of insulating double-glazing maximum arrow is 8 mm.

TRANSVERSES AND FIXED WINDOW-POSTS

During transverses and window-posts application must be used an anti-torsion system documented, in order to avoid profile’s rotation under glass weight.

INTERNAL REINFORCEMENT

Internal reinforcement would be realized thickness minimum 15/10 with form and length compatible with internal section reinforcement chamber of PVC profile. Profile reinforcements must be zinc-coated steel, in order to avoid corrosion. For internal reinforcement, the zinc-coated stratum must be about 100 g/sq.m.; for external reinforcement zinc-coated stratum must be 275 g/sq.m. Externally reinforcement must be zinced also cut sections. Reinforcements, plats or steel profiles used as anchorage thickness 4mm must be zinc-coated. Possible weld beads would be preserved from corrosion with zinc spray without heating (DIN 18360). These reinforcements would be secure to PVC profile with zinc-coated screws from a 50 mm distance from internal angle of door/frame and with a frequency not superior to 500 mm (white profile) and 250 mm (covered profiles). Forms and particular height would be reinforced by satisfying CNR regulation that imposes maximum arrow acceptable not superior to 1/500 of length this for avoiding glass slabs, water and air infiltration.

DRAINAGE

Drainage and slots must be made in conformity to technical directive work of profile’s constructor used for window’s realization. Frame drainage must be made toward outside of window through a different chamber from that has profile’s reinforcement. Outside, slots must be protected from wind, direct action through suitable caps.

GLASS STOP

Glass stops, 45° cut angle, will have square or shaped form, according to architectural requests of D.L.L. and will have a gasket. Glass stop’s thickness will be chosen on the basis of glass thickness and glass gasket. It’s necessary to avoid to create dimensional differences between glass stops placed on fixed and mobile doors, and it’s not accepted application of heights between profile and glass stop.

GASKETS

Holding system to atmospheric agents would be double gasket. It could be used gasket with principal profiles or insert them subsequently to soldering frame/door. Gaskets, when they are in direct contact with atmospheric agents must be built with suitable materials that are able to maintain unaltered this function for years. They must have a high degree of tolerability with elements that are assembled in conformity to DIN 52452 regulation.
It could be used only gaskets in EPDM, silicone, RAU-PREN or similar. Gasket’s material must obey as that present in RAL GZ 716/1, paragraph II regulations.

ACCESSORIES

Ironmongery and accessories will be: Maico. They would be installed on windows in conformity to DIN 18357 regulation. They would have form and closing efficiency compatible with the same profile. They must satisfy controls established by EN 107 regulation. The EURO groove for ironmongery accommodation would have an ironmongery axe 13 mm for allowing installation of not-break-in accessories.

ACCESSORIES Materials and treatment

Steel, die-cost zinc pressure, stainless-steel fro springs of angle movement and plastic material of high quality for different trinkets. All metallic parts are zinc-coated according to DIN 50941 regulation. All silver components are characterized by wax stratum of high quality that increases anticorrosive protection and also fluidity of single piece. On the basis of RAL marching of RAL-RG 607/3 quality (lock and ironmongery for windows) that is RAL-RG 660 (galvanized products) for class of solicitation III, are demanded at least 72 hours of resistance till white rust 240 hours till comparison of red rust. Check is made according to DIN 50021 (saline test fog). La protezione anticorrosione delle superfici Maico corrisponde a quanto viene prescritto dal RAL. Anti – corrosion protection of Maico surfaces correspond to that written to RAL. Maximum weights for door and accessories used max 120 kg with angle hinge and supplemental scissor.

Windows with double-glazing 4-15-BE4 with argo gas and new thermal spacer. French windows with double-glazing 4BE-15-6/7 with argo gas and new thermal spacer. Glass works ( simple glasses, insulation double-glazing) would be made in conformity to that fixed by DIN 18361, DIN 18545 regulations.
