dakraam

A dakraam is a window set into a roof, designed to admit daylight and, in many cases, provide ventilation. The term is Dutch and commonly used in the Netherlands and Flanders; in English, it is usually called a skylight or roof window.

There are several types: fixed skylights that do not open; venting skylights such as top-hung or pivot models; and roof windows that open widely for ventilation. They can be integrated into pitched roofs or sit flush with the surface.

Frames are typically timber, uPVC, or aluminum. Glazing ranges from single to triple panes, often with Low-E coatings. Many dakramen include insulating flashing and weather seals, and can be equipped with blinds, screens, or rain sensors.

Proper installation requires weatherproof flashing and correct alignment with roof lines to prevent leaks. Thermal performance, condensation management, and glare are important considerations, as are local building codes that govern daylight provisions, ventilation, and safety standards for glazing.

Larger openings or locations may require safety glazing. Regular maintenance involves cleaning, checking seals, and replacing worn gaskets. Regulations vary by country and region regarding egress, insulation, and energy efficiency standards for skylights.

Dakramen enhance natural light, support passive cooling, and improve visual connection with outdoors. Their design should balance daylight, privacy, heat gain, and ventilation, with attention to shading and acoustic performance in noisy environments.
