example 1

[0014]A medium-high density polyurethane panel 5, according to the invention (FIG. 1), is obtained by extrusion, comprising a massive part having a substantially planar face 8 and a part comprising some rectangular channels 1 and ribs 2 arranged substantially perpendicularly to the flat face 8. The ratio between the width of the channels 1 and the width of the ribs 2 is 18:1. Preferably, channel 1 width does not exceed 19 mm. The panel 5 also comprises a face 7 consisting of the free ends of the ribs 2, opposite to the planar face 8. The thermal insulation panel thus obtained according to the invention has a weight four times smaller than a massive polyurethane thermal-insulating panel made of the same material, at the same exterior dimensions and achieves the same thermal conductivity, respectively of λ=0.023 W / m×K.

example 2

[0015]A low-density polyurethane panel 6 according to the invention (FIG. 2) is obtained by injection molding in the mold, comprising a massive part having a substantially flat face 10 and a part comprising some trapezoidal channels 3 and ribs 4 arranged substantially perpendicular to the flat face 10. The average ratio between the width of the trapezoidal channels 3 and the width of the ribs 4 is 3:1. Preferably, the width of the channel 3 does not exceed 19 mm. The panel 6 also comprises a face 9 consisting of the free ends of the ribs 4, opposite to the flat face 10. The thermal insulation panel thus obtained according to the invention has a weight four times smaller than a massive polyurethane thermal insulation panel made of the same material and having the same exterior dimensions, and achieves the same thermal conductivity, respectively of λ=0.023 W / m×K.

[0016]The panels according to the invention are used by applying the faces 7, 9 formed by the free ends of the ribs on the s...

Abstract

The invention relates to a thermal insulating panel used for the insulation of buildings. The thermal insulating panel has some rectangular or trapezoidal channels, delimited some ribs obtained by extrusion or injection molding, the average ratio of the width of the channels and the width of the ribs ranging from 18:1 to 3:1, one of the dimensions characterizing by the volume of the channels being smaller than the size at which convection of the air occurs in the channels, such that the thermal exchange to be made exclusively by air conduction.

Description

TECHNICAL FIELD[0001]The invention relates to a thermal insulating panel or board, usable for the insulation of buildings.STATE OF THE ART[0002]Thermally insulating panels made of polystyrene, polyurethane, polyvinyl chloride used for thermal insulation of buildings are known. The disadvantage of these massive thermal insulating panels is the high consumption of material per unit of volume.[0003]It is known that in the case of double pane glass, the maximum insulation level is obtained at a distance of 18 millimeters between the glass sheets, as an optimal result between conduction and convection. At a larger size, convection occurs, and the heat transfer is at least ten times higher. At a smaller size, only conduction occurs, but the level of insulation decreases with the size.DISCLOSURE OF THE INVENTION[0004]The purpose of the invention is to achieve thermal insulating panels made of known materials with very good insulation efficiency, using a much lower amount of material.[0005]...
