Modern and traditional

A feature that sets the SOLID CONSERVATION window apart from other windows is its black exterior finish (the standard for RoofLITE+ is grey) and a vertical black strip that runs the full height of the pane. This ensures that the window complies with monument preservation requirements and can be used wherever these are in place. Despite its traditional appearance, the window has modern parameters. Thanks to its double glazing with two low-emission (heat-reflective) coatings and a standard-width frame, the window offers very good thermal insulation parameters of Uw = 1.3 W/m²K.

A ventilation valve = increased comfort for everyday use

The SOLID CONSERVATION window has a ventilation valve that allows an inflow of fresh air into the room without the need to open the window.

Easy installation in any roof

With an installation flashing dedicated to the CONSERVATION series, SOLID CONSERVATION windows can be installed in virtually any roof with a pitch between 15° and 90°. Importantly, CONSERVATION flashings have the same (black) finish colour as the windows in this range. This results in a tight and aesthetic combination that meets the requirements of monument preservation engineers.
