The original top-operated roof window has an integrated ventilation system, and the handy top control bar makes it suitable for most installation heights and allows furniture to be placed under the window.
GLU is our polyurethane roof window, which is 100% maintenance-free. It's particularly suitable for humid rooms or wherever you want to have maintenance-free convenience. And with our unique insulation system ThermoTechnology™ inside, you get extra powerful and energy-efficient protection from the cold.
New: From 2018 all our roof windows, including the Standard range, are delivered with ThermoTechnology™ and our draught-protection gasket. Together, they make a unique insulation system for the ultimate energy-efficient shield against the cold and draughts.
