INSULATING PANEL MADE OF STONE WOOL, AND CONCRETE INSULATING WALL PROVIDED WITH INSULATING PANELS

摘要

The invention relates to an 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 first layer (21) of a substantially uniform first density and a second layer (23) of a substantially uniform second density different from the first density of said first layer (21), at least one profiled groove (22) being formed in said insulating panel starting from the top face (12) of said first layer (21), 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, wherein the depth of the groove is from 0.5 to 6 cm and wherein said first stone wool layer (21) density is from 100 to 300 kg/m³ and the second stone wool layer (23) density is from 60 to 120 kg/m³. The invention also relates to a concrete insulating wall comprising a concrete slab (26) and insulating panels (10) according to the invention and to a cellar ceiling comprising a concrete insulating wall according to the invention.
