1. A multilayer and insulating construction system for a building, that comprises
a) at least one building member selected from the group consisting of a wall, a ceiling, and a floor,
b) at least one hardened insulation layer associated with the building member, wherein the hardened insulation layer:
(i) has a maximum thickness of between 1 and 60 cm,
(ii) has a Bulk Density (BD) in kg/m3 that is less than or equal to 450; and
(iii) is prepared by mixing, with water, a dry composition (d) comprising:
-A- at least one binder composition including:
A1- at least one binder that is a hydraulic binder or an air binder; and
-B- at least one bio-sourced aggregate based on sunflower stalk and/or corn stalk and/or rape stalk, the bio-sourced aggregate -B- having a Bulk Density (BD) in kg/m3 that is less than 110, and the bio-sourced aggregate including stalk pith in an amount of >99 weight % on a dry basis;
and wherein the dry composition has a ratio of A/B [mass of the binder composition -A- in kg on a dry basis]/ [mass of the bio-sourced aggregate -B- in kg on a dry basis] that is between 1 and 15.
