The Fiamma Vent 40 Crystal Rooflight is a practical and stylish ventilation solution designed to bring natural daylight and fresh air into caravans, campervans and motorhomes. Featuring a transparent Crystal roof dome, permanent ventilation system and integrated mosquito net, this genuine Fiamma rooflight provides a comfortable and well-ventilated interior throughout your travels.
Designed for a 40 × 40cm roof opening, the Fiamma Vent Crystal offers a versatile solution for both new installations and compatible replacement rooflights. Its transparent dome allows daylight to enter the vehicle, helping create a brighter and more welcoming living environment.
One of its standout features is the permanent ventilation system, providing a continuous exchange of air even when the rooflight is closed. With a permanent airflow opening of approximately 80cm², the vent helps maintain air circulation throughout the vehicle without requiring an electric fan.
The rooflight also incorporates an integrated mosquito net, helping prevent insects from entering while allowing fresh air to circulate. This makes it particularly useful during warmer weather when ventilation is essential for maintaining interior comfort.
Its aerodynamic double-skinned dome is designed to optimise airflow over the rooflight while travelling, helping minimise wind noise and vibration. Thanks to its streamlined construction, an additional external spoiler is not normally required.
Opening and closing the rooflight is straightforward using the convenient internal handwheel mechanism, allowing you to adjust ventilation without complicated controls or electrical connections.
Manufactured using durable, UV-resistant materials, the Fiamma Vent Crystal is designed to withstand exposure to sunlight and changing outdoor conditions. Its protective sealing system helps provide a weather-resistant installation when correctly fitted.
The rooflight features a neutral white internal and external frame, creating a clean appearance that complements most caravan and motorhome interiors. The transparent Crystal dome provides a modern alternative to conventional opaque white rooflight covers.
With external dimensions of approximately 45.5 × 45.5 × 8.5cm and a weight of 2.8kg, the Vent Crystal combines a compact profile with practical ventilation performance.
Designed for roof thicknesses of 30–50mm, the rooflight can also accommodate thicker roof structures of up to 85mm when used with the appropriate Fiamma extension kit, available separately.
