Definitions

  • the present invention relates to a method of thermal and/or acoustic insulation of a housing structure.
  • it relates to an ecological prefabricated element where also the realization process is eco-sustainable in line also with CAM (minimum environmental criteria).
  • the state of the art reveals that the current methods of thermal insulation of housing structures provide for the need to create buildings with good performance of energy efficiency, low environmental impact and with an acceptable benefit also in terms of health and not only environmental.
  • the traditional method of making bricks or walls does not take into account the healthiness of indoor and even outdoor environments and their "weight” in terms of ecological footprint.
  • the state of the art in reference to the present buildings shows, moreover, that they are unreliable in terms of guaranteeing the transmittance prescribed in correlation to the construction process to realize them as well as having a realization system quite energy-consuming.
  • the present invention deals with a panel made of decorticated and dedusted straw, hydraulic lime, clay and pozzolan. It has thermal, acoustic and hygrometric comfort, as well as being permeable to water vapor, that is, it is breathable and resistant to frost, insects and rodents, and finally it has a reduced amount of CO2 emissions during manufacture, since it adopts a so-called "cold" process.
  • the panels are laid by gluing them to the existing wall using suitable glue and dowels.
  • the cut can be made by manual or electric saw and the walls, finally, can be covered with a natural network and plastered.
  • This panel is ideal for use as a thermal coat for exteriors to be superimposed on the facades of existing buildings and that require an intervention of energy efficiency. Thanks to its characteristics, it guarantees high thermal insulation performance both at low and high temperatures.
  • this component of green building has an enormous versatility, in fact, can be easily used for the construction of walls in all structures, where the structural elements are made of wood, steel or reinforced concrete. Its main function is to make external perimeter walls of a building. However, it can be suitable not only for external plugging but there is the possibility to use it also to realize internal masonry, in this case it is necessary to add a layer of plaster for internal use.
  • the panel described and the relative method of realization constitute a new and inventive alternative to the state of the art, solving a series of industrial problems linked to the reliability and speed of assembly of the panels themselves as well as the guarantee of having natural materials that strongly reduce the environmental impact of the building.
  • the percentages of preparation of the dry mixture are by weight: Lime, clay and pozzolan between 70% and 85% while straw between 15% and 30%.
  • the screed, to be prepared for the realization of the panels, before being inserted in the clean formworks, is spread on the internal sides, a "veil" of natural oil; the thermal screed is realized having as a percentage: dry mixture of lime, clay, pozzolana and straw that varies, in weight, between 85% and up to 95% while the percentage of the weight of water, varies accordingly, from 5% up to 15%.
  • This panel with the doses mentioned above has a density of cured panels equal to about 554 kg/m3.
  • Figure 1 shows the perspective view of the panel that has an area of about 0.25 m2 (50cm x 50 cm) while the thickness can vary from 5 cm up to 20 cm.
  • FIG. 2 illustrates the production process including the following stages:
