Beschreibung
Zusammenfassung:	A wallboard, a method of preparing a wallboard, and a method of making a gypsum slurry to prepare a wallboard are provided. The wallboard includes a set gypsum dihydrate derived substantially from a non-fibrous form of calcium sulfate and selected from the group consisting of anhydrous gypsum and gypsum hemihydrate. The wallboard also includes an aerogel dispersed in the gypsum dihydrate. Cette invention concerne un panneau de placoplâtre, un procédé de préparation dudit panneau de placoplâtre, et un procédé de fabrication d'une suspension de gypse pour préparer ledit panneau de placoplâtre. Le panneau de placoplâtre comporte un dihydrate de gypse durci dérivé essentiellement d'une forme non fibreuse de sulfate de calcium et choisi dans le groupe constitué par le gypse anhydre et le semi-hydrate de gypse. Le panneau de placoplâtre comporte également un aérogel dispersé dans le dihydrate de gypse.
