As the winter days get longer and spring brings more temperate days and blossoms, the nights are gradually more moderate. But with rising energy costs and a heightened global focus on energy efficiency, it’s important to get the most out of your heater and not let any hot air go to waste. One of the most effective ways to do this is through the use of insulation, and one of the most cost-effective ways to insulate the space you’re building or designing is with a polyisocyanurate installation.
Polyisocyanurate (shorthand “polyiso”) is one of the most widely used building materials in the world. It accounts for more than 75 percent of the insulation used in commercial building construction in North America. It’s most commonly used as continuous insulation or as a protective cover board. A closed-cell, rigid-foam board that is bonded to facers on both sides of the board, polyiso is predominantly composed of organic materials, including polyol, a blowing agent and polymeric methylene diphenyl diisocyanate. This formulation, coupled with its use with different facers, imparts a number of benefits on the user: compatible with a variety of roofing systems, third-party certified long-term thermal performance, low global warming potential blowing agents and industry-wide Environmental Product Declaration.
