Lumi’s clean lines add modern elegance and cutting-edge sophistication to your home’s exterior. They look amazing from the inside too. With a vast expanse of glass, nothing comes between you and your view.
Lumi won’t just transform your home’s appearance, it will look after your family’s safety. That’s why every Lumi window has a high-security locking system and anti-leverage hinge bolts as standard across the range.
Lumi windows are filled with Argon gas, use low E-glass and have internal thermal breaks to retain more heat. That’s good news for your fuel bills and brilliant news for the environment.
Lumi glass is bonded flat to the unit structure and fixed in place with super-tight double gasket technology. It’s not just great for letting light in, it’s brilliant at keeping noise out.
