ESP Low-E® Insulation is the perfect solution for steel building applications of all shapes and sizes. Low-E Insulation installed by itself performs as an insulation, thermal break and vapor barrier. Low-E is often installed in combination with traditional mass insulation to achieve High R-Systems. Low-E is also very effective when installed in retrofit applications when additional insulation is required in existing steel buildings. Low-E insulation products come with numerous features and benefits designed specifically for today’s steel building professionals.
