Buildings use one-third of the nation’s energy, two-thirds of the electricity and account for 40 percent of the country’s climate gas emissions.

As gas and energy prices increase, polyiso can cut building owners’ utility bills and help reduce pollution. A recent independent study (Barrels of Oil Study) found increasing the amount of polyiso insulation used on a roof by one inch beyond ASHRAE standards can save millions barrels of oil and reduce energy costs by billions. Using polyiso insulation saves money for contractors and building owners.

In addition to its energy-efficiency and environmental savings, polyiso cuts construction costs because of its adaptability with a variety of roof systems.  Another study found polyiso insulation can save tens of thousands of dollars in installed costs when compared to other roof insulation materials. (Polyiso Insulation Cost Study). In fact, builders can increase the thickness of polyiso and improve the R-value of the building and still save money on first-cost installation when compared to minimal levels of extruded and expanded polystyrene.

Unlike other insulating materials, the R-value-per-inch of polyiso increases with thickness because of the unique closed-cell structure of the rigid foam boards. Because of its superior R-value and durability, buildings that use polyiso have lower heating and cooling costs.
