Abstract

Insulating panel ( 10 ) having a top face ( 12 ) and a bottom face ( 14 ) opposite the top face, comprising a body ( 20 ) made of stone wool with a part of substantially uniform first density and a part of substantially uniform second density, different from the first density, at least one profiled groove ( 22 ) being formed in said insulating panel starting from the top face, the top face ( 12 ) being made of stone wool, the groove ( 22 ) being formed in the stone wool, the number of grooves being less than or equal to three for 60 cm of a dimension of said panel perpendicular to the direction of the grooves.

First claim

The invention claimed is:

1. An insulating panel having a top face and a bottom face opposite the top face, comprising a body made of stone wool with a part of substantially uniform first density and a part of substantially uniform second density, different from the first density, at least one profiled groove being formed in said insulating panel starting from the top face, the top face being made of stone wool, the groove being formed in the stone wool, the number of grooves being less than or equal to three for 60 cm of a dimension of said panel perpendicular to the direction of the grooves, wherein the groove has a depth of from 0.5 to 6 cm, and wherein the first stone wool density is from 100 to 300 kg per cubic meter and the second stone wool density is from 60 to 120 kg per cubic meter.

2. The insulating panel of claim 1 , wherein the groove has a trapezoidal profile with a small base on the side of the top face.

3. The insulating panel of claim 1 , wherein the groove has a rectangular profile.

4. The insulating panel of claim 1 , wherein the groove has a parallelogram-shaped profile.

5. The insulating panel of claim 1 , wherein the groove has a bottom parallel to the top face and edges of unequal gradients, the width of the groove increasing towards said bottom.

6. The insulating panel of claim 1 , wherein the groove has a transverse profile with a zone of smaller width close to the top face and a zone of larger width at a distance from the top face.

7. The insulating panel of claim 1 , provided with one longitudinal groove for a panel width of from 50 to 70 cm.

8. The insulating panel of claim 1 , provided with two longitudinal grooves for a panel width of from 50 to 70 cm.

9. The insulating panel of claim 1 , wherein the depth of the groove is from 1 to 4 cm.

10. The insulating panel of claim 1 , wherein the minimum width of the groove, in a zone closer to the top face than to the bottom of the groove, is greater than or equal to 15 mm.

11. The insulating panel of claim 1 , wherein the first stone wool density is from 110 to 180 kg per cubic meter and the second stone wool density is from 80 to 105 kg per cubic meter.

12. The insulating panel of claim 1 , wherein the panel allows reversible deformations under the application of a pressure having a value of from 1.5 to 5.0 Newtons/cm 2 on the top face.

13. The insulating panel of claim 1 , wherein the top face forms a face of the part of first density and the bottom face forms a face of the part of second density.

14. Concrete insulating wall, comprising a concrete slab and insulating panels according to claim 1 , wherein the insulating panels are fixed to a bottom face of the slab by introducing concrete into the groove or grooves of the insulating panels.

15. Cellar ceiling comprising an insulating wall according to claim 14 .
