Recticel Powerdeck U PIR insulation boards contribute to improved energy efficiency across a building's entire operational life. Research from PU Europe indicates PIR insulation recovers up to 100 times more energy during its service life than the energy required for manufacturing, resulting in substantial reductions in overall energy consumption and CO² emissions. These boards are manufactured with a zero ODP (Ozone Depletion Potential) blowing agent and low GWP (Global Warming Potential) formulation.
