The fixtures provided will be manufacturedin order to resist to wind pressure and also considering horizontal and vertical loads as follows:
Under stress the maximum acceptable curvature between the frame and the edge of the plate, calculated between two points, corresponds to 1/300th of the length. If double-glazing are usedthe curvature ofedge’s plate, between the frontal edges, must not exceed 8 mm. Resistance to wind load certified by UNI IIP up to class B3 in accordance with DIN EN 12210. In particular, the fixtures will comply with the rules for calculation of resistance to wind load in compliance to DIN EN 1991-1.
Resistance against heavy rain and air permeability
For resistance against heavy rain and air permeability fixtures will conform to rulesDIN EN 12207, DIN EN 12208.
The fixtures will be made with reference to DIN 4108-2 rule and with reference to Directive for Energy Saving no. 2012/27/UE. Based on criteria for transmittance calculation (DIN EN ISO 10077-1), fixtures have a value of thermal transmittance typical of the leaf node - frame of 1.3 W/m2 K.
Construction of frames and doors
Frames and doors will be made by welding the corners with hot melt, in order to resistto the functional loads applied and in accordance with the rules and minimum values of rupture according RAL normative. For transoms and mullions, mechanical junctions of adequate strength, assembled with screws, will be used, as shown by Certification IFT. Seals on doors and frames are made of thermoplastic material (TPE) with a high elastic memory and are heat-sealed to the profile. At any moment is possible to replace the seals by putting them inside manually in the appropriate slots. The French doors have been designed to use a lower aluminum threshold of maximum height 2.5 cm
All steel reinforcements used will be produced in material type FE-P02-Z-275 NA, treated against rust, with a wall thickness of 1.5 mm. All main profiles will be strengthened with galvanized steel profiles suitable for predictable conditions, and a minimum thickness of 1.5 mm for both white and coated profiles. For entrance doors the reinforcement used will be that of closed tubes welded with a minimum thickness of 3 mm. In order to improve stability, this reinforcement will be welded at the corners with a PVC corner radius. The reinforcement connections of the profiles will be secured with galvanized screws, positioned 30 cm from one another.
Installed hardware will comply with DIN 18357 rule and a certification of quality will be provided with. The check documentation refer to the expected stress and to constructive dimensions of manufactured frames. Hinges supports and scissors supports, together with ratchet and closures must be adjustable.The corner support has torun the door safely and must avoid the window comes out from its hinges when the door is open. Scissor of flap door must avoid door comes out of hinges or it will open. Appropriate plastic covers will be used to match the handle in order to cover the elements of visible hardware when the door is closed. Fixtures are provided with multiple locking points, so that the distance between two consecutive points does not exceed 700 mm. The hardware will have a double anti-corrosion zinc treatment and chrome plating and will have a surface finish in silver color. It will be assembled with screws fixed on at least two walls of PVC or, they’ll be fixed on a PVC wall and on a metal reinforcement. A perimetricallock on 4 sides will be provided as well. For entrance doors the used lock will be automatic with three closure points. At least three heavy anti-breakage hinges will be used with adjustments on XYZ axis.
If not expressly required by customer double glazing and double sealing insulation, transparent or frosted will be used. Thickness of glass is 4mm [chamber + Argon] – 33.1 BE black WE for windows with a base having height exceeding 100 cm from the floor; for lower heights and French doors insulatedglass 33.1 [chamber + Argon] - 33.1 BE black WE will be used.
For glazing workings the following directives will be applied:
-UNI 7697 “ Security measures in glass applications”
-DIN EN 12488:2016 “ Glass for building - Recommendationsfor setting up”
-Producer’s warranty for insulated glass
-DIN 7863 for elastomer gaskets
The glass depth joint will be 20mm. The bottom of the joint is inclined,with no protrusions and allows a full support of dowels and spacers. The single foot glazing beads will be positioned on the inner side of the casing, cut to size, and assembled so that they snap in place with no sloping between them. The pieces of glazing will have a length of 100 mm and shall be secured so as not to slide. They’ll be made with a non- perishable material when in touch with butyl. Panels’assemblage is standard with appropriate glazing beads. Glazing beads will be suitably dimensioned according to glass thickness.
