What is polyisocyanurate insulation?
Polyisocyanurate thermal insulation, commonly referred to as polyiso, has proven to be popular due to a combination of its cost effectiveness (i.e. cost per insulation unit), efficiency (i.e. insulation value per unit thickness), and fire resistance, as compared to some competitive materials. Polyiso has recently come to represent over 75% of the commercial roof insulation market. However, as polyiso has grown in popularity, so has the interest in understanding a more exacting insulation value of this material. With rising energy costs it is more important to accurately specify heating, ventilation, and air conditioning equipment (HVAC). In addition, once a building is completed, it is important that the owner/occupier be able to better anticipate future energy costs from a budgetary perspective.

What is thermal insulation?
Thermal insulation is an important part of commercial roofing assemblies. The aim of this article is to examine the factors influencing the thermal resistance, known as R-value of polyiso. The prediction of long term R-value and the influence of climate, i.e. temperature, have been of significant interest over the past few decades as building energy budgets have increased in importance. Recent discussions as to what R-value the designer should use and the importance of ambient temperature are reviewed and discussed.
How does insulation affect the heat?
Insulation has two main effects on heat flux into and out of a building. During the summer, flux of the heat from the sun down into a building is reduced . Similarly, reflective membranes also reduce the amount of heat but do so by reflection.
