The RV Innotec Sky Dome 4 is a premium rooflight designed for motorhomes, caravans and campervans with a 400 x 400mm cut-out. This skylight fits roof thicknesses between 25-50mm and weighs 4.9kg. The unit measures 51.3 x 51.3 x 12cm when closed, extending to 41cm when fully open. With CE conformity and TÜV Rheinland certification, it includes dimmable LED lighting, UV-resistant glazing, and an aerodynamically shaped acrylic glass cover with ECE approval.
How does the Sky Dome 4 compare to other 400x400mm rooflights?
The Sky Dome 4 features two opening positions with a forced ventilation capacity ranging from 0 to 106cm³, allowing you to control airflow based on conditions. The removable internal seal provides permanent ventilation when needed. The quick-release locking mechanism includes an aluminium operating handle for easy access from inside your vehicle. High-quality impact-resistant acrylic glazing protects against weather and UV damage whilst maintaining excellent clarity.
Both fly screen and sun protection come fitted with single-pleated fabrics, featuring magnetic closure on the aluminium end bars for straightforward operation. The polyester fly screen maintains rigidity across temperature changes. The interior frame and glazing materials resist UV degradation, maintaining their appearance and function over years of use. Installation requires a 402 x 402mm aperture, making it a direct replacement for standard 400 x 400mm roof vents.

Frequently Asked Questions
The Sky Dome 4 accommodates roof thicknesses between 25-50mm. This range covers most motorhome, caravan and campervan roof constructions. The installation requires a 402 x 402mm cut-out aperture, making it compatible with standard 400 x 400mm rooflight openings. You should measure your roof thickness before ordering to ensure a perfect fit.
The Sky Dome 4 features a removable internal seal that allows permanent ventilation even when the dome is closed. This forced ventilation provides airflow from 0 to 106cm³ without opening the rooflight, which is safer whilst travelling. The unit has ECE approval for road use. When you need ventilation during transit, simply remove the internal seal rather than leaving the dome in an open position.
The Sky Dome 4 includes dimmable LED lighting integrated into the rooflight frame. The lights connect to your 12V leisure battery system and can be adjusted from full brightness to low ambient lighting. LED technology provides energy-efficient illumination whilst drawing minimal power from your battery compared to traditional halogen lights. The lights remain functional independently of whether the rooflight is open or closed.
The Sky Dome 4 uses impact-resistant acrylic glazing rather than polycarbonate. Acrylic provides excellent light transmittance, stays clearer over time without yellowing, and weighs less. Acrylic is also more scratch-resistant and maintains a beautiful high-gloss finish. The impact-resistant modification in this rooflight combines acrylic's clarity advantages with enhanced durability for motorhome use.
Clean the polyester fly screen and single-pleated sun protection using warm water and a soft cloth with mild soap if needed. Avoid harsh detergents or chemical cleaners. For light cleaning, use a microfibre cloth or vacuum with a soft brush attachment to remove dust and debris. The magnetic closure system on the aluminium end bars makes the blinds easy to extend for cleaning. Clean the screens every few months to maintain optimal airflow and appearance.
The 402 x 402mm cut-out requirement makes the Sky Dome 4 compatible with standard 400 x 400mm rooflight apertures in most motorhomes and caravans. This is one of the most common rooflight sizes used in European recreational vehicles. However, you should verify your existing cut-out dimensions and roof thickness falls within the 25-50mm range before ordering as a replacement unit.
The two opening positions let you control ventilation based on weather conditions. The lower position provides moderate airflow whilst minimising rain entry during light showers. The fully open position maximises ventilation for cooking, showering or warm weather. The quick-release locking mechanism and aluminium operating handle make switching between positions straightforward from inside your vehicle.
The Sky Dome 4 holds CE conformity marking, TÜV Rheinland certification for quality assurance, and ECE approval for vehicle use on European roads. These certifications confirm the rooflight meets safety standards for motorhome and caravan installation. The UV-resistant materials in both the glazing and frame are tested to withstand prolonged sun exposure without degradation.
The aerodynamically shaped acrylic cover reduces wind resistance and noise when driving at motorway speeds. This design minimises drag, which can help improve fuel efficiency compared to box-shaped rooflights. The streamlined profile also reduces wind whistle and vibration noise inside your vehicle. The 12cm closed height keeps the overall roof profile low whilst the dome extends to 41cm when fully open.
Forced ventilation in the Sky Dome 4 works through the removable internal seal. When you remove this seal, air can circulate through the rooflight even with the dome closed, providing 0 to 106cm³ of airflow. This system prevents condensation build-up overnight or during winter storage whilst keeping rain out. You can adjust the ventilation by partially or fully removing the seal based on your needs.
