FAQs
What is the primary benefit of the opaque finish?
The opaque finish diffuses incoming light and provides privacy, making it ideal for bathrooms or bedrooms.
Can this be installed on a sloped roof with a 30-degree pitch?
No, this specific model is engineered exclusively for flat roofs with pitches between 0 and 15 degrees.
Does the dome come with the base unit?
No, the dome is an upper component and requires a separate compatible Velux base unit for full installation.
Is the polycarbonate material prone to yellowing?
The dome is manufactured with high-quality, durable polycarbonate designed for long-term outdoor exposure.
How do I keep the dome clean?
The curved profile allows rain to wash away most debris naturally, but you can clean it with a soft cloth and mild detergent if required.
Can I use external blinds with this dome?
Yes, this dome is compatible with a range of external and internal blinds to help manage light and heat.
Troubleshooting
Water pooling around the base of the dome
Check if the roof pitch is within the 0-15 degree specification and ensure the base unit flashing is properly installed.
Difficulty installing blinds
Verify that you are using genuine Velux-compatible blind kits designed for this specific dome and base unit series.

Setup, Compatibility & Care
Installation must be performed on roof structures with a pitch between 0 and 15 degrees. The dome is designed to be mounted onto a pre-installed Velux base unit; ensure the base is properly sealed according to standard roofing practices to prevent leaks. Compatibility with blinds is integrated, allowing for easy mounting of manual or solar-powered blinds on the interior or exterior. For care, the domed design reduces the need for frequent cleaning. However, when cleaning is necessary, use mild soap, water, and a soft cloth to avoid scratching the polycarbonate surface. Avoid harsh chemicals or abrasive scrubbing pads that could damage the outer finish or impact resistance.
