Abstract
Description
- The present invention relates to constructions made of wooden materials particularly adapted to the manufacturing of window frames.
- Many types of window frames are presently known in the art and differ from one another by their construction and above all the materials they are made of.
- In fact, in recent years, beside the traditional wooden frames also metal window frames have been produced both in metal sheet and aluminium alloy, open-joint and thermal conduction blocking types, with single and double window panes.
- Window frames of aluminium sections have been advertized for some years because of their high capabilities of thermoacoustic insulation and tightness.
- Such metal materials, however, have a quite unnatural appearance when compared with the wooden window frames that, in contrast, give a pleasant sensation of warmth and insulation just by touching them, even if they have a lower thermal as well as acoustic insulation efficiency.
- Moreover, in recent times, the so-called bio-building industry has developed a great deal with the result of a return to the natural construction materials also for indoor and outdoor window frames.
- The main object of the invention is then to overcome the above-mentioned problems and to provide a novel wooden material which is capable of ensuring a particularly improved thermal and acoustic insulation.
- This has been achieved according to the invention by providing a multilayer material consisting of two outside wooden layers and at least one inside layer made of high-density cork agglomerate.
- A better understanding of the invention will result from the following detailed description with reference to the accompanying drawings which show some preferred embodiments by way of a not limiting example.
- In the drawings:
- Figures 1 and 2 show two types of multilayer sections according to the invention, i.e. one cork agglomerate layer between two wooden layers, and two cork agglomerate layers sandwiched among three wooden layers, respectively;
- Figure 3 is a partial perspective view of a window frame made of the material according to the invention;
- Figure 4 is a cross section of the upright of the window frame of Fig. 3; and
- Figure 5 is a cross section of the horizontal base of the window frame of Fig. 3.
-
- Figures 1 and 2 show, by way of example, two sections of multilayer material according to the present invention, the section of Figure 1 being used for the window frames from Figure 3 on, Figure 2 showing a section with two cork agglomerate layers A sandwiched among three wooden layers L.
- It is evident that the greater the number of the alternated layers, the better the thermoacoustic insulation.
- In particular, the multilayer section according to the invention is made by sticking at least one high-density cork agglomerate layer A between at least two wooden layers L. Advantageously, such cork agglomerate A has density and mechanical characteristics similar to wood, however, it is generally isotropic because of its homogeneity and has then neither preferential strain directions nor different resistance according to the direction to which the load is applied.
- According to the invention, the sticking is carried out by using a press and glues of the known type with high mechanical resistance.
- It should be noted that the arrangement of a multilayer material as described above allows a number of advantages to be attained, thus making its application particularly useful. In fact, because of its high mechanical characteristics, cork agglomerate A allows a section with mechanical resistance similar to the presently used wooden sections to be provided, with the advantage that such cork agglomerate section is not subjected to the typical deformations of the solid wood which is, as known, a "live" material that is suffering from changes in temperature and humidity causing bending and in some case also cracking.
- Moreover, as far as the thermoacoustic insulation and thermal conduction blocking is concerned, the arrangement of at least three different layers strongly increases the insulation characteristics over those of the same materials arranged separately.
- The method of producing such multilayer material provides, in case of a three-layer material, the following steps:
- a) laying a first wooden layer on the lower plate of a press;
- b) smearing a glue onto the upper surface of said first wooden layer to form an adhesive film;
- c) laying a cork agglomerate layer on said adhesive film of the first wooden layer;
- d) smearing a glue onto the upper surface of said cork agglomerate layer to form an adhesive film;
- e) laying a second wooden layer on said adhesive film of the cork agglomerate layer;
- f) lowering the upper plate of the press to the surface of the second wooden layer;
- g) heating the plates of the press to about 150-170°C;
- h) applying and keeping a pressure to the arranged multilayer material for about five minutes so as to cause the glue to set;
- i) removing the obtained multilayer material from the press.
-
- It is understood that, in case of a multilayer material with more than three layers as in Figure 2, the method will be the same as that described above taking only care that the outermost layers are always made of wood and the innermost layers of cork agglomerate are separated by the wooden layers.
- According to the invention, steps a) to e) can also be executed outside the press by laying the multilayer material already arranged to be stuck between the plates of the press and going on to step g).
- A further alternative can relate to the fact that the plates are kept to the same operating temperature as step g) so as to prevent them from being heated and cooled every cycle.
- In the specific case illustrated in Figures 3 to 5, the window frame has a slot S for a single or double pane, a water drain channel C, preferably of aluminium, plastic or other commonly used material, and rubber seals that increase the sealing action and eliminate the draughts.
- With reference to Figures 3 to 5, the basic aspect of the invention is to provide a novel multilayer material to be used for window frames according to the known building techniques.
- In the case where the multilayer material according to the invention is used for window frames, one or two inside layers of cork agglomerate separated by a wooden layer are usually sufficient.
- The layer or layers of cork agglomerate contribute not only to a better thermoacoustic insulation but can also take up any little "movement" or deformation of wood due to climatic conditions (temperature, humidity degree, etc.).
- The particular glue used to join tightly the wooden layers and the cork agglomerate layers to one another has preferably the main feature to set in about five minutes at the temperature of about 150-170°C. A glue which lends itself to such purpose is the two-component glue known under the abbreviation D4 certified by UNI standards.
- The press by which the wooden layers and the cork agglomerate layers of the multilayer material are compacted is preferably of the high-frequency type.
- The present invention has been described and illustrated according to two preferred embodiments thereof, however, it should be understood that different changes and modifications can be made without departing from the scope of the appended claims.
