Description

Insulating sandwich panel
The present invention relates to the insulating sandwich panel intended for use in construction industry as thermal and sound insulation.
The insulating plates used so far in the construction industry arecharacterisedusually by either a very high level of thermal performance or a very high level of fire resistance. Therefore a technical problem that has been raised to be solved in the invention is the development of such a structure of the insulating sandwich panel that would becharacterised bythermal performance similar to the level achieved by foam insulating material and at the same time by fire resistance similar to the level achieved by mineral fibre materials.
The patent specification PL204538 reveals a curtain wall of the building, in particular a residential building where between the building wall and the finish coat there is an insulating platecharacterised bythe fact that the isolating plate has holes perpendicular to the wall structure, which account for 21% of the surface of the insulating plate, and the spacing between these holes is preferably even or greater than the cross-section of the holes. The insulating plate has through-holes with a diameter of 3 (mm) . The insulating plate is covered from the external side of the building with a vapour-permeable coating into which a fibreglass mesh is embedded that supports the external plaster.
In turn, the patent specification PL206193 reveals a curtain wall of the building, in particular a residential building, where between the building wall and the finish coat there is an insulating platecharacterised bythe fact that the isolating plate has holes inclined at an angle to the wall structure, which account for 6% of the surface of the insulating plate, and create a preferably regular structure that allows to achieve a diffusion resistance coefficient of approx. 20. These holes are preferably over 3 [mm] large.
Moreover, the specification in the application WO2004054799 reveals a vapour-permeable, heat reflective membrane with a heat reflective coat, such as aluminium foil applied onto the surface of the vapour permeable base, such as non-woven fibres. And there are many small slots, cracks in the surface of this foil.
In turn the patent specification PL192673 reveals a heat insulating plate made in particular from expanded plastic and available in any shape, preferably a rectangular prism and with two front faces, preferably flat and at least one, preferably four, side faces, preferably flat,characterised bythe fact that at least the front faces of the plate are interconnected by through-holes.
While the patent specification PL170894 reveals a wall cladding of the building comprising prefabricated plate fittings with heat insulating properties, and the heat insulating core of a single fitting comprises mainly a layer of expanded brittle material. The nature of this invention is that between the heat insulating core and the building wall there is a layer of soft foamed plastic that adheres tightly to the building wall. This layer and the insulating core, forming the body of the fitting, are interconnected by expansion.
The specification CN203383448 reveals a solution that is a wall made of carbon fibre in the form of a honeycomb, which comprises a carbon internal coat with a porous structure in the form of a honeycomb and the external decorative coat.
The purpose of the invention is the development of an insulating plate with fire resistance typical for mineral fibre materials and at the same time the improvement of insulating parameters typical for foam insulating materials. The additional purpose of the solution according to the invention is to achieve the effect of sound insulation.
The insulating sandwich panel, comprising the permanently interconnected layers, of which one is made of mineral wool while the other of foamed plastic, ischaracterised bythe fact that the first layer comprises the mineral wool with the thermal conductivity coefficient ranging from 0.030 W/m*K to 0.038 W/m-K and with the self-weight load ranging from 0.5 kN/m<3>to 1.5 kN/m<3>, while the second layer comprises the polyurethane foam with the thermal conductivity coefficient ranging from 0.010 W/m*K to 0.030 W/m*K and the density ranging from 25 kg/m<3>to 100 kg/m<3>. While the third layer comprises glass fleece adhering directly to the first layer with the thickness ranging from 0.3 to 2.00 mm, with wind barrier properties.
Moreover, the second layer preferably includes air through slots.
Preferably when the second layer, on the surface non adhering to the first layer, is covered with the insulating material that traps the air in air slots.
Preferably when the insulating material covering the second layer on the surface non adhering to the first layer comprises the mineral wool with the thermal conductivity coefficient ranging from 0.030 W/m-K to 0.038 W/m-K and with the self-weight load ranging from 0.2 kN/m<3>to 0.8 kN/m<3>. The use of such a material at the place where the sandwich panel adheres to the insulated surface corrects the unevenness and curvatures of this surface and thus reduces air circulation in the holes in the second layer of the panel.
Moreover, preferably when the air slots are in the shape of regular hexagons which additionally stabilizes the panel structure.
In addition, preferably when on the outer edges of the panel there are notches and tongues that allow to create a shaped lock between two or more panels.
The invention solves the raised technical issue. The main advantage of the invention is the ability to discharge outside the vapour accumulated in the wall. The use of the insulating sandwich panel according to the invention, in particular due to the trapping of still air in air slots in the second layer, provides insulation related to heat saving and noise reduction with simultaneous discharge of vapour condensate.
The present invention in the example of execution is presented in the attached figure, where Fig.l presents the general view of the insulating sandwich panel with a part section in the first example of execution. Whereas Fig.2 presents the general view of the insulating sandwich panel with a part section in the second example of execution. In turn Fig.3 presents the general view of the insulating sandwich panel in the second example of execution.
