The Fiamma Vent 28 F is a compact 280mm x 280mm roof vent designed specifically for small spaces in motorhomes, caravans, campervans and van conversions. Available with either a white opaque or crystal transparent lid, this manually-operated rooflight features Fiamma's sandwich mounting system that allows installation without drilling additional holes through the roof. The unit provides 80cm² of permanent ventilation through its double-layer cover and comes equipped with a removable aluminium mosquito net that's easy to clean. Weighing just 1.8kg with external dimensions of 320mm x 340mm x 90mm, it suits roof thicknesses from 28mm to 50mm as standard, or up to 68mm with the optional extension kit.
Why choose a 280mm roof vent for motorhome bathrooms and small spaces?
The 280mm size offers the optimal balance between functionality and space efficiency for compact areas like bathrooms, shower rooms and small kitchens where larger 400mm vents won't fit. This size provides adequate light and ventilation without compromising headroom or interfering with adjacent fittings, whilst the 25cm x 25cm internal light opening delivers sufficient natural light for practical use. The compact footprint makes it particularly suitable for van conversions where roof space is limited and for replacing factory-fitted bathroom vents in older motorhomes and caravans.
Manufactured from high-quality UV-resistant and shockproof materials, the Vent 28 F features an aerodynamic low-profile design that eliminates the need for a spoiler, reducing drag and wind noise during travel. The handwheel opening mechanism allows manual operation with precise control, whilst the patented rubber seal and watertight construction prevent rain ingress even when driving at speeds up to 130km/h. The vent opens with hinges facing the vehicle front, and can be upgraded with the optional Turbo-Vent 28 F kit to add a 12V reversible fan for powered extraction. Installation requires a 280mm square roof aperture, with recommended sealants including Sikaflex 710, Dekalin 1512 or Therostat II for professional weatherproofing.
The Fiamma Vent 28 F is commonly used by self-builders converting panel vans into campervans, motorhome owners replacing ageing bathroom vents, and caravan owners seeking improved ventilation in washrooms and toilet compartments. Its white frame design matches modern vehicle interiors, whilst the crystal option maximises natural light transmission for darker spaces. The permanent ventilation helps meet BS EN 1646-1 and BS EN 721 safety ventilation standards for habitable compartments in motor caravans, making it suitable for VASP homologation when building or converting leisure vehicles to legal motorhome standards.

Frequently Asked Questions
The Fiamma Vent 28 F suits roof thicknesses from 28mm to 50mm as standard. For roofs between 50mm and 68mm thick, you'll need the separate Fiamma Kit Extension Vent 28 F. The sandwich mounting system means you fix it from inside without drilling extra holes, using the supplied screws that come in two lengths: 3.5mm x 30mm screws for 28-40mm thick roofs, and 3.5mm x 50mm screws for 40-50mm thick roofs.
Yes, the Fiamma Vent 28 F is designed to be upgraded with the Fiamma Kit Turbo-Vent 28 F, which adds a 12V five-blade motorised fan for powered extraction and ventilation. The Turbo-Vent kit fits onto the existing mounting points and offers reversible airflow, variable speed control, and typically draws 1.1-1.8 amps from your 12V system. This upgrade is particularly useful for bathroom ventilation in hot weather or when showering.
The white version has an opaque white lid that blocks direct sunlight whilst still allowing diffused light through, reducing glare and heat buildup inside. The crystal version features a transparent clear lid that maximises natural light transmission, ideal for darker bathrooms or areas needing maximum illumination. Both versions have identical white internal and external frames, the same permanent ventilation area of 80cm², and identical weatherproofing performance. The choice depends purely on whether you prioritise light transmission or sun shading.
Cut a 280mm square hole in your roof where the vent will sit. Apply sealant like Sikaflex 710, Dekalin 1512 or Therostat II to the underside of the external frame with minimum 10mm width following the rails. Place the external frame in the opening with hinges facing the vehicle front. From inside, position the internal frame and secure using the four supplied screws, tightening evenly to bring the frames together without deforming them. Finally, clip the mosquito net frame into place using the pressure hooks and remove the protective plastic from the lid before use.
Yes, the Fiamma Vent 28 F meets the requirements for VASP homologation in the UK and Europe. It's certified to regulation 43R (E11) and provides 80cm² of permanent high-level ventilation, which contributes towards the mandatory ventilation requirements under BS EN 1646-1 and BS EN 721 for motor caravans. For VASP approval, one 280mm vent typically covers habitable areas up to 5 square metres, though you'll also need appropriate low-level ventilation and compliance with other safety standards. Always consult your VASP engineer for specific homologation requirements.
No, the Fiamma Vent 28 F features an aerodynamic low-profile design that doesn't require a spoiler. The shaped external dome channels air smoothly over the vent during travel, reducing drag, wind noise and vibrations. This design has been tested at highway speeds and performs well up to the maximum recommended vehicle speed of 130km/h. The spoiler-free design also means simpler installation and a cleaner appearance on your motorhome or caravan roof.
Yes, the aluminium mosquito net is designed to be easily removed for cleaning. Simply unclip the net frame from its pressure hooks inside the vent, then wash with water and neutral detergent. The aluminium construction resists deformation and yellowing unlike plastic nets, maintaining its effectiveness over time. The rigid frame clips back into place securely once clean and dry. Regular cleaning prevents buildup of dust and debris that could restrict airflow through the permanent ventilation system.
Check all fixing screws periodically, especially after the first few kilometres of travel and before long journeys, as vehicle vibration can loosen them. Clean both the internal and external surfaces using only neutral non-aggressive detergents. For the crystal cover, use acrylic glass cleaner with a soft cloth to avoid scratching. Never use glass cleaners, all-purpose cleaners, abrasives or alcohol-based products. If the handwheel mechanism becomes stiff, apply a few drops of grease to the lid opening device. Remove any snow or ice buildup from the vent and always ensure it's properly closed before driving.
