要旨 : リバーロック 160 ハゼをベースとし断熱材としてグラスウールをはさんだ2種類の断熱二 重折板屋根「上部ハゼ下部重ね型」「上部下部共ハゼ型」の断熱性能,遮音性能を調べた。 専用金具の強度を調べるとともに屋根材と組み合わせて動風圧試験機により嵌合強度実験 を行い,実物件に対応する安全性を確認した。屋根については耐火性能が要求されるので, 断熱樹脂の検討を行い,(財)建材試験センター中央試験所にて屋根 30 分耐火試験に合格し 建設省の個別認定を受けるに至った。 Synopsis :

Two types of insulated-cladding systems suitable for roofs were developed. Each system comprises three parts, namely, and external profiled sheet using RIVER LOCK 160 standing seam roofing, glass-fiber insulation blanket, and two types of internal profiled sheets (RIVER LOCK WH and RIVER LOCK WK). Heat-insulation, sound-insulation and mechanical properties of the systems have been examined, and the roofing systems have passed the 30-min of fire resistance test of JIS A 1304.
