The e-book, Specifying Polyiso Insulation, offers an overview of polyisocyanurate (ISO) insulation, and how to incorporate them in a project. This curated collection of technical articles from The Construction Specifier illustrates:

• high-density polyisocyanurate cover boards offer comprehensive strength that protects the low-slope commercial roof system from traffic, puncture, and hail damage;
• when used correctly, vapor retarder materials like polyiso insulation can be an effective solution for moisture control; and
• the use of continuous insulation (ci) systems on walls is changing the way specifiers, design professionals, and builders look at the building envelope.
