Daylight is essential for your health, mood and well-being
VELUX flat roof windows bring up to three times more daylight than traditional façade windows, ensuring better light distribution and eliminating dark corners. This transforms your home into brighter, more welcoming spaces – and with convenient ventilation options, you can enjoy fresh air whenever you need it.
What to consider when choosing a flat roof window
VELUX flat roof windows come in a range of designs, sizes and comfort levels. Here’s what to keep in mind when choosing the right solution for your home:
The exterior surface
The exterior surface matters for both style and performance.
The VELUX Standard glass rooflight stands out with its clean, framed glass-top design – a clear upgrade from traditional plastic domes, giving your flat roof a modern, elegant look.
Want even more design impact or higher performance? Explore our flat or curved glass rooflights with glass-to-edge aesthetics.
The size of the rooflight
To maximise daylight, your roof window should cover at least 10% of the room’s floor area.
The Standard glass rooflight fits most residential needs – perfect for renovations and extensions in moderately insulated homes. For larger spaces, maximum daylight or best sound and thermal insulation, choose our flat and curved glass rooflights - which also come in bigger sizes.
The glazing of your windows
Glazing impacts comfort, insulation and noise levels.
The Standard glass rooflight delivers balanced energy performance and everyday comfort, with better insulation and durability than plastic domes.
Need extra performance? Our flat and curved glass rooflights are available with double or triple glazing for enhanced energy efficiency and sound reduction.
VELUX also offers specialised solutions – smoke ventilation, roof exits and burglar-resistant products – to support comfort and safety for every building need.
