Description Stronger than a speeding bullet, able to capture the sun's rays -- Romag may not leap tall buildings, but its Security and Transport glass made of polycarbonate laminates is blast resistant; this product is used in limousines and security vehicles and is popular with military and government agencies, banks, courts, high-end retail shops, and police stations. Its specialty glass products offer safety, renewable energy, and windows on the world. The glass specialist makes customized PV (photovoltaic) panels under brand name PowerGlaz. Its Architectural glass (tinted or solar control coated) provides insulation and protection. Housing developer Gentoo Group bought Romag in early 2011.
