Windows for pitched roofs: light and comfort where you need it most

Pitched roofs often present a common challenge in homes and renovation projects: how to make the most of the space under the roof without sacrificing natural light, thermal insulation and effective ventilation. Dark attics, ceilings with condensation or rooms that do not ventilate properly are some of the recurring problems in this type of construction.

At DISPER, we offer a specialized range of windows for pitched roofs that transform these spaces into bright, comfortable and fully habitable areas. Whether in renovation projects or new constructions, our models are designed to solve real needs with practical solutions that integrate seamlessly with the architecture.

We offer pivot, top-hung and combined opening roof windows, available in wood or PVC, adapting to the intended use and installation environment. Models such as Designo R45, Designo R75, Designo R45 PVC and Designo R75 PVC allow you to choose the most suitable system depending on the roof pitch, exposure to humidity or maintenance requirements.

In addition, our roof windows can be equipped with accessories such as curtains, blinds and interior shutters to improve light control, privacy and energy efficiency. With different opening options, insulation levels and finishes, each model is designed to meet a specific need, adding functional, aesthetic and technical value.
