Duas consequ\u00eancias pr\u00e1ticas decorrem disso. Primeiro, para a mesma temperatura de face fria, uma camada de refor\u00e7o microporosa pode ter de um meio a um ter\u00e7o da espessura de uma camada de silicato de c\u00e1lcio, o que devolve volume \u00fatil ao vaso. Segundo, com espessura igual, o casco opera mais frio e a perda de calor cai correspondentemente. A placa tamb\u00e9m \u00e9 mais leve: nosso grau padr\u00e3o tem densidade de 220\u2013280 kg\/m\u00b3, ent\u00e3o um revestimento mais fino de material mais leve reduz significativamente o peso total do revestimento.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Onde o silicato de c\u00e1lcio ainda faz sentido<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">O silicato de c\u00e1lcio continua sendo uma escolha razo\u00e1vel onde \u00e9 necess\u00e1rio suporte de carga mec\u00e2nica na pr\u00f3pria camada de isolamento, onde o or\u00e7amento domina a decis\u00e3o e onde a espessura extra do revestimento n\u00e3o custa nada porque o vaso j\u00e1 est\u00e1 constru\u00eddo. A placa microporosa tem baixa resist\u00eancia mec\u00e2nica e deve ser protegida do impacto direto de chama e da abras\u00e3o por uma camada de refrat\u00e1rio de trabalho \u2014 a mesma regra que declaramos em nossa p\u00e1gina de produto. \u00c9 um isolamento de refor\u00e7o, n\u00e3o um revestimento de trabalho.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Orienta\u00e7\u00e3o para sele\u00e7\u00e3o<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Escolha placa microporosa quando a espessura ou o peso do revestimento for restrito, quando as metas de temperatura do casco ou perda de energia forem rigorosas, ou quando voc\u00ea estiver eliminando gargalos de um vaso existente sem ampliar o casco. Fique com o silicato de c\u00e1lcio quando o isolamento precisar suportar carga mec\u00e2nica ou quando o custo inicial for o \u00fanico crit\u00e9rio.
