Rooflight Vent 28 F Crystal

The Fiamma Vent 28 F Crystal is a 280mm x 280mm rooflight that's become a go-to choice for motorhome bathrooms, shower rooms and compact spaces where larger vents simply won't fit. This manually-operated unit uses Fiamma's sandwich mounting system, which means you're fixing it from inside without drilling extra holes through your roof. The crystal transparent lid maximises plant-based light transmission, making it particularly effective in darker bathrooms or washrooms where you want as much daylight as possible. It provides 80cm² of permanent ventilation through its double-layer cover and comes with a removable aluminium mosquito net that clips out for cleaning. 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 if you add the optional extension kit. What makes this vent practical for van conversions and caravan upgrades is its aerodynamic low-profile design that eliminates the need for a spoiler, reducing drag and wind noise when you're travelling. The handwheel mechanism gives you precise control when opening, whilst the patented rubber seal keeps rain out even at speeds up to 130km/h. Installation requires a 280mm square roof aperture, and you'll want to use proper sealants like Sikaflex 710, Dekalin 1512 or Therostat II for weatherproofing. The vent opens with hinges facing forwards, and if you need powered extraction later, you can upgrade it with the optional Turbo-Vent 28 F kit that adds a 12V reversible fan. The permanent ventilation meets BS EN 1646-1 and BS EN 721 standards for habitable compartments in motor caravans, making it suitable for VASP homologation when you're converting panel vans or registering DIY camper builds.
