37. FIBERGLASS ENVIRONMENTAL FACTORSResearch By Enermodal Engineering – Canada Glass (silica sand): 65 – 85% Ample worldwide supplyResin: Thermoset Polyester “Relatively small” petroleum contentProcess resins: re-blended and reusedInterior sash and frame insulation: polystyrene – petroleum base with some concern for pentane blowing-agent escapeBoth glass fiber and resin manufacturing are closed processes with “few emissions to the environment.”No ozone-depleting chemicals used in fiberglass window manufacturingEnergy efficiency and long life significantly reduce energy consumptionEnermodal Conclusion Energy use was considered to be the most important environmental factor. From this analysis it was found that fiberglass windows have the lowest overall environmental impact.
