MEMBRANE CEILING SHEET AND MEMBRANE CEILING USING THE MEMBRANE CEILING SHEET
To provide a membrane ceiling sheet and a membrane ceiling using the membrane ceiling sheet that have an excellent elongation rate in oblique directions.SOLUTION: In a membrane ceiling sheet 1 containing glass fiber woven fabric and resin and/or starch that covers at least a part of the surface of glass fibers constituting glass fiber woven fabric, the weaving structure of the glass fiber woven fabric is twill weave or satin weave, the ignition loss of the membrane ceiling sheet is 1 mass% or more and 5 mass% or less, the air permeability of the membrane ceiling sheet is 1 to 50 cm3/cm2/sec, and regarding the exothermic test which is measured according to 4.10.2 heat generation test/evaluation method in "Fire protection performance test/evaluation work method manual" (revised version dated March 1, 2014) of Japan Testing Center for Construction Materials by irradiating the surface of the membrane ceiling sheet from a radiant electric heater with radiant heat of 50 kW/m2, the maximum heat generation rate after the start of heating does not exceed 200 kW/m2 continuously for 10 seconds or more, and the total heat generation amount is 8 MJ/m2 or less.SELECTED DRAWING: Figure 3
【課題】斜め方向の伸び率に優れた、膜天井用シート及び膜天井用シートを用いた膜天井を提供する。【解決手段】ガラス繊維織物と、該ガラス繊維織物を構成するガラス繊維の表面の少なくとも一部を被覆する、樹脂及び／又は澱粉と、を含む膜天井用シート１であって、前記ガラス繊維織物の織組織が綾織又は朱子織であり、前記膜天井用シートの強熱減量が１質量％以上５質量％以下であり、前記膜天井用シートの通気度が１〜５０ｃｍ３／ｃｍ２／秒であり、一般財団法人建材試験センターの「防耐火性能試験・評価業務方法書」（平成２６年３月１日変更版）における４．１０．２発熱性試験・評価方法に従って測定される、輻射電気ヒーターから膜天井用シートの表面に５０ｋＷ／ｍ２の輻射熱を照射する発熱性試験において、加熱開始後の最大発熱速度が１０秒以上継続して２００ｋＷ／ｍ２を超えず、かつ、総発熱量が８ＭＪ／ｍ２以下である、膜天井用シート。【選択図】図３
