カットボール教太郎の世界史つぶやき（屋根瓦・・・）

・こんにちは！カットボール教太郎です！！（屋根瓦・・・）
・１軒１５００～２０００枚！瓦の人気は今も衰えず・日本の屋根といえば、もちろん瓦！と思いきや、実際のところはそうでもない。アメリカで開発された、石綿とセメントが原材料の「カラーベスト」やトタンなど、ローコストな屋根材が意外と幅をきかせている。瓦はやや高価だが、通気性や断熱性、遮音性などに優れ、圧倒的に長持ちするなど、変わらぬ人気を誇っている。瓦の年間出荷額は１５００億円程度。そのほとんどが、昔から良質の粘土がとれた、三州・淡路・石洲の三大産地のメーカーで製造されて全国に出荷されている。なかでも愛知県の「三洲瓦」は全国の瓦生産量の４０％程度を占める。屋根の施工をする業者は一般に、工事の注文があった時点でメーカーから瓦を仕入れる。通常、坪あたり８０～１００枚程度の瓦が必要となり、２０坪の一軒家なら１５００～２０００枚。色はシルバーと黒が人気だ。新しい屋根材との競合に勝つために、瓦そのものの性能だけではなく、施工までふくめた提案や、屋根意外の部分への瓦製造技術の応用などが求められている。・★Ｓ型瓦・・・３万円/坪（うち瓦代２万円）葺く際にミリ単位の精度が求められるので、工事には熟練が必要。耐用年数８０～１００年★平板瓦・・・１万６０００円/坪（うち瓦代９０００円）洋風住宅に似合うデザイン。軽く、地震に強い。耐用年数８０～１００年★セメント瓦１万４０００円/坪（うち瓦代７０００円）最近は軽量でひびわれしにくいものも登場している。耐用年数２０～２５年★カラーベスト・・・１万２０００円/坪（うち瓦代６０００円）石綿とセメントが材料のスレート屋根葺き材。暑さ１ミリ～２ミリ。バブル崩壊以後の主流。耐用年数１０年～１５年★トタン１万円/坪（うち瓦代４０００円）安価だか、雨音がうるさいのが欠点。耐用年数１０年～１５年
