Flush roof louvre window by Lacker

Lacker's bigAir® roof louvre window is designed to permit flush installation in tile roofs. It is the first roof louvre unit that is suitable for listed buildings. The assembly dispenses with projecting components to create a flush, all-glass effect. bigAir® blades are available either in a lapped arrangement – to emulate the look of roof tiling – or as plane models. Lacker window units are fabricated on a project-specific basis to custom sizes, making them ideal for the predetermined dimensions of openings in listed buildings. Insulated frame sections and glass blades with double or triple glazing are standard.
