Definitions

  • Object of the present invention is a system for producing high insulating aluminium-wood mixed winged window and door frames.
  • the systems with cold aluminium profiles do not provide the use of the so called “thermal cut”, that is the “thermal” interruption between the aluminium profile and the wooden one, but they are coupled in various ways depending on the requirements.
  • the thermal cut aluminium-wood systems instead, are made up of profiles usually separated by an insulating material which interrupts the thermal continuity between the inside and the outside, thus guaranteeing a high level of thermal insulation.
  • a typical way of introducing said plastic material is for example its interposition between two different aluminium profiles with the wooden profile to be applied on the last aluminium profile. Therefore, the final configuration is schematically: aluminium - polyamide - aluminium - wood.
  • Aim of the present invention is to allow the production of high thermal-insulating window and door frames (on average higher than the performances of thermal cut aluminium-wood window and door frames) at costs slightly deviating from the "cold" systems (approximately 10% more), since it is a system for producing aluminium-wood mixed window and door frames where the thermal interruption occurs by means of a sole complex profile in insulating material (techno-polymer) which couples with the aluminium profile before production cutting according to different coupling ways (snap-coupling, insertion-coupling, dovetail-coupling).
  • 1 indicates various kinds of aluminium profiles usable in assembling window and door frames; similarly 2 indicates the respective wooden profiles, while 3 indicates the profiles in techno-polymer, which are complementarily shaped with respect to the relative aluminium profiles.
  • the new features are highlighted by the assembly of said components shown in fig. 4 , where it is shown an absolutely non-limiting embodiment of the assembly of the three said components, which is the base for obtaining the final frame.
  • the interruption of the thermal transmission is provided by using a sole variably shaped profile 3 in insulating material, (usually a techno-polymer as polyamide), which is interposed between the aluminium profile 1 and the wooden profile 2.
  • the coupling between polyamide 3 and wooden profile 2 is guaranteed by the provision of fixing dowels 4, which are housed in the suitable recess 3', of which the various polyamide strips are provided, as shown in fig. 3 .
  • the polyamide strip 3 is provided with slightly arched projections 3", which are introduced in the respective recesses 1' on the aluminium profile 1.
  • the coupling between the two parts can occur simply "by snap", that is by exerting a suitable pressure of the polyamide strip 3 on the aluminium profile 1, so that the projections 3" are restrained in the recesses 1' of the aluminium profile 1.
  • This operation is made possible thanks to the mechanic features of the two materials (aluminium and techno-polymer, as polyamide), which are both very resistant materials and apt to obtain high precision extruded profiles.
  • the resulting profile is therefore a thermally high-performance polyamide profile plus aluminium (1 and 3) and obtainable with very reduced costs thanks to the elimination of further processing steps as knurling and rolling, which instead are needed to obtain insulating profiles by means of the classic thermal cut technology.
  • Figs. 5 and 6 show instead various examples of the final assembly of the above-described principal components, according to the production system object of the present invention. It is clear that these are example embodiments since generally the casings are to be adapted to the different assembly conditions depending on the case.
  • fig. 5 above for example, it is shown a section of a thermal cut casing, near the frame 5, in case the same is flush with the wall 6 (built in).
  • all the above-described components are shown: the aluminium profiles 1, the wooden profiles 2 and the polyamide profiles 3 "snapped" on the respective aluminium profiles and interposed between them and the wooden ones.
  • the double glass 7' as well in intermediate position between the aluminium and wooden profiles by means of almost clip shaped suitable insulating seals 8.
  • the same insulating seals 8 are arranged in different points of the casing as for example between the various profiles (aluminium, polyamide or wood) belonging to the various elements of the window and door frame (frame, casing, wall), always in order to provide the interruption of the thermal continuity.
  • WING WING COST/ML COST PER KNOT SAVING% Trasmitt ECOWIN W85 0.715 € 1,00 € 3.86 0,927 € 1,60 € 5,31 € 9,17 1,96 HYDRO Wood85TT 1,316 € 7,Z4 1,6 € 8,80 € 16,04 74,9% 2,54 ALCAN EUROW 1,306 € 7,18 1,369 € 7,53 € 14,71 60,5% N.D.
  • the computing way used for the "typical" model ECOWIN is the following: the cost per knot resulting is the sum of the cost of the aluminium profile, obtained multiplying the weight for the price by kg of the cold profile, plus the cost per linear meter of the polyamide profile. For all the other systems the cost is calculated multiplying the cost per kg of the thermal cut aluminium profiles for the weight of the assembled thermal cut profiles. The comparison is carried out excluding the cost of the wooden profiles and of the fittings and hardware which can be considered equal for all the systems, possible differences being negligible. The high saving in percentage terms of the "typical" window and door frame "ECOWIN" is clear with respect to the principal competitors, while maintaining a high standard of thermal insulation at the same time.
