Products details

  • In short
    Mono pitched solutions are single rows of VELUX Glazing Panels that light up hallways, corridors and large rooms. The panels can be installed between 15-90° on either an upstand (on a flat roof), in a saw tooth roof or as a non-protruding installation in a sloped roof. Solutions mounted against a vertical wall at the top can be installed in pitches between 15-60°. The glazing panel system offers multiple corner solutions as hips, valleys and vertical glass gables, making the system ideal for refurbishment as it can be designed to fit an already existing hole in the roof.

    The panels and key accessories are prefabricated off-site, thus facilitating a quick and safe installation.

    VELUX Glazing Panels are delivered with a 10-year guarantee on panels and flashings. Actuators and electrical components that are a part of the glazing panel system come with a 3-year guarantee.

    VELUX Glazing Panel specialists offer support throughout design, specification and installation, including a project specific sub-construction drawing with measurements for the outer geometry.
    Please note that sub-constructions are not included in the VELUX offering.

  • Details
    The prefabricated panel consists of aluminium frame profiles with a glazing unit sealed in using a UV resistant sealant material. When the panels are joined together on-site, the outer gasket and an inside drainage profile must be mounted to secure drainage.
    The glazing panel system is delivered with installation profiles, gaskets and flashings, ensuring a weathertight solution.

    VELUX Glazing Panels have a recommended minimum installation height of 2.5 m above floor level (inside) and ground level (outside). In case of installation below that level, safety measures must be applied by the installer/user to prevent serious injury. No instruction or measure can eliminate the inherent hazards resulting from installation heights below 2.5 m.
