SOUND ABSORBING SHEET FOR MEMBRANOUS CEILING
PROBLEM TO BE SOLVED: To provide a sound absorption sheet for a non-combustible membranous ceiling suitable for an indoor membranous ceiling construction and a luminous ceiling membranous construction excellent in light weight and performance effect by illumination and video projection and having an anti-resonance effect.SOLUTION: A sound absorption sheet 1 for a membranous ceiling includes an embedding part 3-1 into which a part of a resin fire-resistant layer 3 has infiltrated inside a nonwoven fabric 2 in a laminating interface between the nonwoven fabric 2 and the resin fire-resistant layer 3 as a laminate disposed with the resin fire-resistant layer 3 including a silicon-based resin or a soft vinyl chloride-based resin on one surface of the nonwoven fabric 2 with the nonwoven fabric 2 including a glass filament in a main body as a base material. The depth of this embedding part 3-1 has 1 to 35% of the thickness of the nonwoven fabric.SELECTED DRAWING: Figure 1
【課題】軽量性を有し、照明や映像投影による演出効果、音の反響防止効果に優れ、屋内の膜天井構築用、光天井膜構築用に好適な不燃性の膜天井用吸音シートを提供する。【解決手段】膜天井用吸音シート１はガラス長繊維を主体に含む不織布２を基材に、不織布２の片面にシリコーン系樹脂又は軟質塩化ビニル系樹脂を含む樹脂難燃層３を設けた積層体として、不織布２及び樹脂難燃層３との積層界面において、不織布２の内部に樹脂難燃層３の一部が侵入した埋没部３−１を有する。この埋没部３−１の深さが不織布の厚さに対して１〜３５％とする。【選択図】図１
