Outro ponto hostil das setoriza\u00e7\u00f5es ocorre quando temos que permitir a circula\u00e7\u00e3o livre do ar e, ao mesmo tempo, sermos efetivo na prote\u00e7\u00e3o contra o fogo.<\/p>\n
As Grelhas Tecsel\u00ae <\/strong>s\u00e3o l\u00e2minas de palusol encapsuladas em PVC. O palusol est\u00e1 formado por silicato de s\u00f3dio hidratado, uma pequena quantidade de mat\u00e9ria org\u00e2nica e refor\u00e7ado com fibra de vidro. Seus dois lados levam uma camada de resina ep\u00f3xi que serve para proteger a camada interm\u00e9dia das influ\u00eancias clim\u00e1ticas (\u00e1gua, vapor de \u00e1gua e CO2<\/sup>).<\/p>\n
Quando se excede os 100 \u0366C, a Grelha Tecsel\u00ae<\/strong>, expande-se e forma uma camada de espuma de poros finos n\u00e3o combust\u00edveis \u00e0 compress\u00e3o, que atuam como isolante t\u00e9rmico e impede assim a passagem do calor, chama e fumos.<\/p>\n
No caso que n\u00e3o se produza um inc\u00eandio, a grelha permite que os sistemas de ventila\u00e7\u00e3o transportem o fluxo de ar para o que foram desenhadas.<\/p>\n

As Grelhas Tecsel\u00ae <\/strong>fixam-se mecanicamente ao suporte com uso de parafusos, buchas ou fixa\u00e7\u00f5es adequadas (elas devem possuir pelo menos a mesma resist\u00eancia ao fogo que o suporte ao que se fixam).<\/p>\n
Se existem espa\u00e7os vazios entre a grelha e a obra suporte \u00e9 necess\u00e1rio rematar com M\u00e1stique intumescente Tecsel\u00ae. <\/strong><\/p>\n
Se a superf\u00edcie de ventila\u00e7\u00e3o \u00e9 maior que as dimens\u00f5es das grelhas, \u00e9 poss\u00edvel montar as mesmas em espinha, sempre e quando mantenhamos a resist\u00eancia do fogo e a consist\u00eancia da obra nas separa\u00e7\u00f5es das Grelhas Tecsel\u00ae. <\/strong><\/p>\n
