Daylight and Heat Control for Modular Skylights

Explore our great selection of products to control daylight, heat and glare

Control daylight and heat to create the best indoor climate. Modular Skylights are designed to optimise the indoor climate and offer options such as integrated blinds or special glazing to control daylight, heat and glare.

Roller Blinds

The fully integrated roller blinds control daylight, heat and solar glare through the rooflight. The blinds are supported by thin, free-floating wires to create an invisible effect. Blinds are available with fire-retardant cloth in grey, white and black.

To minimise the light spillage around the edges, a dim out solution with aluminimum profiles fitted in module frame is available. The dim out profiles can be pre-mounted from the factory or mounted during installation on-site.

To support a fast and safe installation of the skylight solution, you can order the roller blinds pre-mounted from the factory.

VELUX roller blinds 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.

Glazing with Sun Protection – Opal and Fritted

Low emissivity coating

Opal glazing

Fritted glazing

With opal glazing, Modular Skylights create a subtle and uniform lighting without any glare. 

Fritted glazing is used to create a distinctive light/shadow effect inside the building and partly reduces glare.

Glazing with Sun Protection - Electrochrome

Glazing with electrochrome glass in clear state. Visible light transmission 57%

Glazing with electrochrome glass in intermediate state. Visible light transmission 15%

Glazing with electrochrome glass in fully tinted state. Visible light transmission 1%

Modular Skylights are available with electrochromic panes. The electrochromic pane is an insulated glazing unit with electronic, tintable coating. The coating can be darkened on demand by applying a low voltage of electricity. The dynamic changing in tint provides exceptional control of daylight, glare and energy use without blinds or shades.

An easy-to-use control system allows anyone to operate the electrochromic panes with wall switches, a mobile app or with a building management system. A combination of the three is also possible.

Photovoltaic Glazing

Green Solution House, Bornholm, Denmark

Modular Skylights can be delivered with photovoltaic glazing units, fully or partly covered. The solution combines Integration of renewables into the rooflight to optimise energy efficiency and roof space.

Furthermore, the photovoltaic panels create a shadow effect in the building that reduces heat gain and glare.

Infill Panels

Modular Skylights are available with infill panels to accommodate for instance a ventilation shaft or an existing wall construction.

Infill panels can also be used on the south-facing side of a Ridgelight to imitate a shed roof structure
