Can polyiso insulation be used to achieve points under the LEED rating system?
• Highest Thermal Efficiency – Polyiso is the most thermally efficient insulation available in the marketplace, as determined using Long Term Thermal Resistance (LTTR) values, a 15 year time-weighted R-value. In addition, members of PIMA initiated a third party certification program – Quality MarkCM – to validate these thermal values. Quality MarkCM is a voluntary program administered by FM Approvals, one of the nation’s most dependable testing organizations. Well-insulated buildings reduce fossil fuel use thereby reducing air pollution. Zero Ozone Depleting Potential – All PIMA polyiso manufacturer members produce rigid foam board with third-generation, zero ozone-depleting blowing agents. All polyiso products are now HCFC-free and CFC-free. Zero Global Warming Potential – All PIMA polyiso manufacturing members produce rigid foam board with zero global warming potential blowing agents. This quality is critical as the impact of climate change, or global warming, is acknowledged as a wo
