The Isabella Ventura Air Alto is a premium motorhome porch awning that uses a sophisticated interconnected air tube system for rapid setup. Available in three widths (260cm, 330cm, or 400cm) with a depth of 250cm and mounting height range of 260-280cm, this awning inflates through a single valve using the included 12V electric pump. The connected air system distributes pressure automatically throughout the structure, reducing leak points and maintaining stability when temperatures fluctuate. Twelve foam pads come supplied to fill gaps against your motorhome's bodywork or level out uneven pitches, while the included connection pad folds to create a weatherproof seal.
Built from printed polyester roof fabric and fibre-dyed VenTex polyester sides, the Ventura Air Alto transforms from enclosed space to open sun canopy by unzipping all panels. Sides and fronts roll back individually for creating extra doorways on warm days, while the two smaller models (260cm and 330cm widths) accept the included veranda pole for a partially-open configuration. Roof ventilation panels and side-mounted mosquito nets provide airflow without letting insects through. The heavy-duty PVC inner skirt stops ground moisture creeping up, and Isaflex rubber straps with black base trim give a more upmarket appearance than standard awning components.
Isabella has pre-fitted attachment rings inside for adding an optional inner roof liner, which cuts down condensation during spring and autumn when overnight temperatures drop. Optional annexes attach to either side when you need sleeping quarters or storage space separate from the main awning area. The package includes curtains, pegs, draught skirt, standard wheel cover, transport bag and electric pump. One limitation worth noting: the veranda configuration only works on the 260cm and 330cm models, so the 400cm width can only be used fully enclosed or completely open as a sun canopy.

Frequently Asked Questions
All air tubes are physically connected as one continuous system rather than having multiple separate tubes with joints. This means you inflate through a single valve and the air distributes automatically throughout the entire structure. The design eliminates weak points where tubes typically join together, reducing pinching, twisting and potential leak spots. When temperature changes cause air pressure to fluctuate, the pressure automatically equalises across all tubes instead of leaving some sections over or under-inflated.
The foam pads serve two purposes. You can place them between your motorhome's bodywork and the awning fabric to fill gaps caused by curves, panel joints, windows or roof racks, creating a draught-proof seal. Alternatively, position them underneath the air tubes when pitched on sloping or uneven ground to prevent the awning structure twisting or leaning. The connection pad that comes with the awning folds in half to create additional sealing at the attachment point where the awning meets your motorhome.
Measure your motorhome's awning rail length where you plan to attach the awning. The 260cm width suits compact motorhomes and works well for couples needing porch space. The 330cm middle size accommodates most standard motorhomes and provides room for a small table and chairs with storage space. The 400cm width fits larger motorhomes or when you need separate living and storage areas. All three sizes have the same 250cm depth projection from your motorhome and fit mounting heights between 260cm and 280cm. Remember the veranda pole function only works with the 260cm and 330cm models.
The printed polyester roof material has the pattern applied to the surface after the fabric is manufactured, creating a decorative textile appearance that resists fading and cleans easily. VenTex sides use fibre-dyed polyester where the colour goes through the entire thread before weaving, producing a more breathable material that creates better air circulation inside the awning. This combination gives you a durable waterproof roof with better ventilated side walls, reducing stuffiness during warm weather while maintaining full weather protection.
Inflation time varies by awning width but typically takes 3-5 minutes for the 260cm model, 4-6 minutes for the 330cm and 5-8 minutes for the 400cm width when using the included 12V pump connected to your motorhome leisure battery. The single valve has a rubber membrane that seals automatically when you disconnect the pump, preventing air loss during inflation. For deflation, open both valves to release air quickly, usually taking 2-3 minutes to deflate sufficiently for packing.
The interconnected air system maintains stability better than separate tube designs because pressure equalises automatically, but you should still follow standard awning safety practices. Use all supplied pegs and guy lines, and consider adding storm straps in exposed locations. If winds exceed 30mph or gusts become sustained, partially deflate the awning by 10-15% to reduce wind resistance and prevent damage. The awning performs well in typical British weather conditions but isn't designed to stay up during storm-force winds that would damage any awning structure.
The optional inner roof creates an insulating air gap between itself and the main awning roof, significantly reducing condensation when temperatures drop overnight. This matters most during spring and autumn when warm air inside meets cold roof fabric, causing water droplets to form and drip. The inner roof also provides a more finished appearance inside and slightly improves heat retention. Installation uses the pre-fitted rings already sewn into the awning structure, so fitting takes minutes without modifications.
All front and side panels unzip completely from the awning frame, converting the enclosed space into an open-sided canopy supported by the inflated tube structure. This works well during hot weather when you want shade without enclosed walls. For partial opening, the 260cm and 330cm models accept the included veranda pole to hold up one front section while keeping other panels attached, creating a covered porch area. The 400cm width doesn't support the veranda pole configuration, so it only works fully enclosed or completely open.
The complete package includes the awning with interconnected air tubes, 12V electric pump for inflation, twelve foam pads for sealing gaps or levelling, connection pad for motorhome attachment, draught skirt, standard wheel cover, curtains for privacy, transport bag, pegs for ground anchoring and one veranda pole (260cm and 330cm models). You don't need to purchase additional inflation equipment or basic fittings. Optional extras available separately include the inner roof liner for condensation control and matching annexes that attach to either side for extra living or storage space.
Clean the awning while erected using lukewarm water and a soft brush or sponge, working from top to bottom. For stubborn marks on the printed polyester roof or VenTex sides, use Isabella's own cleaning products or mild soap solution, avoiding harsh chemicals that damage waterproof coatings. Rinse thoroughly and let the awning dry completely before packing away to prevent mould growth. The PVC inner skirt wipes clean easily. Check air pressure before each trip and inspect valves for debris. Store in a cool, dry location away from direct sunlight when not in use.
