It\u2019s melted down to 2,600 degrees Fahrenheit and then spun into fibers. The process yields a fire-resistant material that can withstand temperatures above 2,000 degrees Fahrenheit.<\/p>\n<p><b>Mineral Wool Insulation Applications<\/b><\/p>\n<p>Thermafiber<sup helvetica=\"\" neue\",=\"\" helvetica,=\"\" arial,=\"\" sans-serif;=\"\" font-weight:=\"\" 400;\"=\"\">\u00ae<\/sup> mineral wool insulation can be used in a variety of applications:<\/p>\n<ul>\n<p>\u00b7as thermal insulation for the required R-value that keeps buildings warm in winter and cool in summer, it offers an R-value of up to 4.3 per inch of thickness;<\/p>\n<p>\u00b7as acoustical material for commercial, residential and industrial applications, to isolate and control noisy equipment in mechanical rooms or control sound between treatment or patient rooms in a hospital;<\/p>\n<p>\u00b7for construction joints to fill and protect the void between fire-rated structures against the spread of fire.<\/p>\n<p>\u00b7for high-temperature applications like ovens, furnaces, kilns or anything requiring high-temperature processes \u2014 for an oven heated to 1,300 degrees Fahrenheit, it keeps the process temperature in line and covers that oven to protect employees working next to the equipment from burns;<\/p>\n<p>\u00b7as the integral component of the perimeter fire barrier assemblies in high-rise buildings where a rated floor and a non-rated exterior wall meet \u2013 to achieve fire code compliance and designed to prevent the passage of flame and hot gasses through the interior joint, without compromising design aesthetics. Thermafiber<sup>\u00ae<\/sup> mineral wool insulation is also installed within the spandrel panel of the curtain wall, since aluminum and glass walls can be compromised in a fire. \u201cFirst, it will help protect a portion of that non-rated wall, and second, it\u2019s inserted in the joint between slab and the non-rated curtain wall,\u201d Ogino says. \u201cThat joint starts at the face of the floor slab and goes out to the curtain wall. It\u2019s critical to protect that spandrel to keep that horizontal protection in place. The idea is not to rate the wall, but to keep the joint material in place, so if there\u2019s a fire, it stops it from spreading and contains it to the room of origin,\u201d Ogino says.<\/p>\n<\/ul>\n<div class=\"wp-caption\">\n\t\n\t<img class=\"lazy\"\n\t\tsrc=\"https:\/\/blog.architizer.com\/wp-content\/themes\/architizer\/assets\/images\/blank.png\"\n\t\tdata-src=\"https:\/\/architizer-prod.imgix.net\/media\/1477576444444f2708ad089c6d3b8daa0ed30ec39a932.jpg?fit=max&#038;w=1680&#038;q=60&#038;auto=format&#038;auto=compress&#038;cs=strip\"\n\t\t\t\t\tdata-srcset=\"https:\/\/architizer-prod.imgix.net\/media\/1477576444444f2708ad089c6d3b8daa0ed30ec39a932.jpg?fit=max&amp;w=1680&amp;q=60&amp;auto=format&amp;auto=compress&amp;cs=strip 1680w,https:\/\/architizer-prod.imgix.net\/media\/1477576444444f2708ad089c6d3b8daa0ed30ec39a932.jpg?fit=max&amp;w=1080&amp;q=60&amp;auto=format&amp;auto=compress&amp;cs=strip 1080w,https:\/\/architizer-prod.imgix.net\/media\/1477576444444f2708ad089c6d3b8daa0ed30ec39a932.jpg?fit=max&amp;w=760&amp;q=60&amp;auto=format&amp;auto=compress&amp;cs=strip 760w,https:\/\/architizer-prod.imgix.net\/media\/1477576444444f2708ad089c6d3b8daa0ed30ec39a932.jpg?fit=max&amp;w=625&amp;q=60&amp;auto=format&amp;auto=compress&amp;cs=strip 625w,https:\/\/architizer-prod.imgix.net\/media\/1477576444444f2708ad089c6d3b8daa0ed30ec39a932.jpg?fit=max&amp;w=368&amp;q=60&amp;auto=format&amp;auto=compress&amp;cs=strip 368w\"\n\t\t\tsizes=\"(min-width: 1680px) 1680px,(min-width: 1080px) 1080px,(min-width: 760px) 760px,(min-width: 625px) 625px,368px\"\n\t\t\t\talt=\"\u00a9 Iwan Baan\"\n\t\titemprop=\"contentUrl\"\n\t>\n\t<p class=\"wp-caption-text\">\u00a9 Iwan Baan<\/p>\n\t<\/div>\n\n<p><b>Thermafiber Insolutions<sup>\u00ae<\/sup><\/b><\/p>\n<p>Thermafiber Insolutions<sup>\u00ae<\/sup> is the technical services provided by Ogino\u2019s department for commercial building systems. \u201cBecause each system is unique, my department gets specific drawings and comes up with a tested system that\u2019s close to construction details,\u201d she says. \u201cIf necessary, we do an engineering judgment to evaluate how that particular construction will perform in a fire situation.\u201d<\/p>\n<p>Thermafiber, conducted extensive in-house testing and collaborations with Underwriters Laboratory (UL). \u201cWe had the first tested and listed perimeter fire barrier system in the Underwriters Laboratory directory,\u201d she says.
