One such subject is the <strong>\u201cinstrumented seal\u201d<\/strong> \u2014 a term that <strong>does not appear explicitly in the National Building Code of India (NBC) 2016<\/strong>, but is very much connected to fire safety principles discussed in the code.<\/p>\n<hr class=\"wp-block-separator has-alpha-channel-opacity\">\n<h2 class=\"wp-block-heading\">Instrumented Seal: Not Named in the Code, But Still Relevant<\/h2>\n<p>If you search NBC 2016 for the term \u201cinstrumented seal,\u201d you won\u2019t find a direct reference. This can lead to confusion, especially among specifiers, safety officers, and project consultants. However, the <strong>function<\/strong> of an instrumented seal \u2014 i.e., sealing penetrations and maintaining the integrity of fire-rated enclosures  <strong>is addressed under another name<\/strong>.<\/p>\n<p>That term is: <strong>Firestop Assemblies<\/strong>.<\/p>\n<hr class=\"wp-block-separator has-alpha-channel-opacity\">\n<h2 class=\"wp-block-heading\">Firestop Assemblies: What NBC 2016 Actually Mentions<\/h2>\n<p>In <strong>Part 4 (Fire and Life Safety)<\/strong> of NBC 2016, the code outlines detailed guidelines on the use of <strong>firestop systems<\/strong> wherever services like cables, ducts, pipes, or structural joints pass through fire-rated walls, floors, or ceilings.<\/p>\n<p>These systems are:<\/p>\n<ul class=\"wp-block-list\">\n<li>Tested for <strong>fire resistance and thermal insulation<\/strong>,<\/li>\n<li>Meant to <strong>maintain compartmentation<\/strong> during a fire,<\/li>\n<li>Required to be installed using <strong>certified and compatible materials<\/strong> (e.g., sealants, intumescent wraps, collars, gaskets).<\/li>\n<\/ul>\n<hr class=\"wp-block-separator has-alpha-channel-opacity\">\n<h2 class=\"wp-block-heading\">Application in Fire-Rated Doors<\/h2>\n<p>At <strong>Sehgal Doors<\/strong>, we pay special attention to these sealing systems in all our <strong>fire-rated door installations<\/strong>.
