Products details

In short

A step solution is configured by installing multiple rows of panels on top of each other using a structural beam to connect the rows. Mono pitched step solutions can be installed between 15-90°. Dual pitched step solutions can be installed between 25-60°.
The glazing panel system offers multiple corner solutions as hips, valleys and vertical glass gables, making the system rather bespoke and ideal for refurbishment as it can be designed to fit an already existing hole in the roof.

The panels and main parts of the accessories are pre-fabricated 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.

Dual pitched step solution with hipped ends.

A hip is an external facing corner solution used to connect two adjacent sloping sides of a rooflight.

A valley is an internal facing corner solution used in the intersection between two individual rooflights.
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.
