Groenberg Alvar Rooftop Tent
Hard-shell rooftop tent for 2 people – aerodynamic, robust, semi-automatic. Ready for Scandinavian road trips, off-road mountain tours and spontaneous micro-adventures – wherever the road takes you.
The Groenberg Alvar is an aluminium hard-shell rooftop tent that combines uncompromising comfort with fast setup and takedown. The semi-automatic opening mechanism with STABILUS gas struts turns setting up camp into a matter of seconds – not minutes. Ideal for those who'd rather spend their time outside than wrestling with tent poles.
Key Features & Technical Highlights
Universal Compatibility
Fits almost any vehicle with a dynamic roof load of at least 77 kg and suitable roof bars. The static load capacity when stationary is typically much higher.
Wind Resistance up to Force 8
The Alvar's aerodynamic triangular shape withstands wind forces up to Beaufort 8 – reliable even in rough weather conditions.
Low Profile & Fuel Efficiency
Only 12 cm profile height when closed – minimised drag for noticeably lower fuel consumption on long drives.
300 kg Load Capacity
Sturdy aluminium frame with a maximum interior load capacity of 300 kg – exceptionally robust and built to last.
Dimmable LED Lighting
12V LED interior lighting with 3 dimmer levels and an integrated USB port – the right light for every situation.
Memory Foam Mattress
Memory foam mattress with a removable, machine-washable flannel cover for maximum sleeping comfort – night after night.
Ventilation & Condensation-Free
3D Airmesh mat beneath the mattress ensures optimal air circulation and effectively prevents condensation build-up.
8,000 mm Waterproof Rating
High-quality ripstop polyester with a waterproof column of 8,000 mm – reliable protection in any weather.
Organiser with Touch Function
Integrated organiser with touch function keeps devices and essentials within reach – even in the dark of night.
Large Windows & Insect Mesh
Generous windows serve as entry points, featuring fine-mesh insect screens for optimal ventilation and an unobstructed view.
Canopy & Rain Protection
The integrated canopy shields against rain and sun, allowing windows to remain open even in poor weather.
Telescopic Ladder & Shoe Bag
Includes a 2.30 m telescopic ladder (6.2 kg) and a hanging shoe bag for 2 pairs. Optional 2.60 m ladder available as an accessory.

Login
With the appropriate roof racks, our roof tents can be mounted on almost any car. (Convertibles excluded!) If you are unsure, please contact us by e-mail (info@groenberg.com) with as much of the following information as possible:
1. make, model name
2. year of construction
3. roof load (in the operating instructions)
4. roof rails yes/no?
To prolong the service life of the roof tent, it should be maintained regularly and cleaned when dirty. Firstly, the dried dirt should be carefully brushed off with a soft brush. The mattress cover can be completely removed and washed in the washing machine at 30**°** for easy care. The interior can be carefully vacuumed with a hoover or, better still, a hand hoover. Only then should mild detergent and a soft sponge be used. It is important that the roof tent is dried again before folding it up so that no mould can form. If mould does form, it can be cleaned with a mixture of water and vinegar. For particularly stubborn mould, please use a mould remover.
The roof tent should be stored dry and not closed. There is a risk of mould forming when it is closed. The tent must not be loaded during storage.
The recommended maximum speed of 120 km/h should not be exceeded. Please find out which legal regulations apply in the respective country before setting off.
No. Our roof tents are impregnated at the factory and can be used without pre-treatment. If the impregnation wears off after a few years, an impregnation protection, especially for roof tents, should first be tested on an inconspicuous area.
A few spare parts can be found in our shop.If something should break while travelling, our service team is on hand with advice and spare parts available at short notice.
Our telescopic ladders are 2.3 metres long.An extra long ladder (2.6m) can be ordered additionally.
Children love roof tents. For this reason, our roof tents are also suitable for children.
Both variants have many advantages, but also a few disadvantages.Here is a list of the most important ones:
**Softtop (folding roof tent):**
Advantages: significantly lighter than a hard shell, sleeping area doubles, usually covered entrance, usually cheaper price
Disadvantages: Usually takes longer to set up, not as aerodynamic, more susceptible to wind
**Hardtop (hard shell roof tent)**
Advantages: very quick to set up, more aerodynamic, significantly quieter when travelling, offers storage space for blanket, pillow, sleeping bag etc., more legal parking space options (tent does not protrude over vehicle)
Disadvantages: rather impractical for small cars as the footprint is too large, higher weight
Theft-proof nuts delay or even prevent theft, as the nuts can only be loosened with special tools. Another option is to attach a ring-head nut with a padlock to the screws. A GPS tracker can also be an advantage.
The roof load can be found in the owner's manual or can be obtained from the manufacturer. A distinction must be made between the dynamic and the static roof load.
The accessory articles can be found on the article page of the respective roof tent.
Our standard ladders are 2.3 metres long.For particularly high vehicles, we recommend our 2.6m ladder.
Depending on the model, the side walls may or may not be completely removable. This detailed information can be found in the product description of the roof tent.It can be recognised from the product photos.
Our roof tents do not have a power connection. We recommend using a power bank or a mobile battery.
As a standard, our roof tents are not equipped with built-in lighting. This allows you the flexibility to customize your setup to your specific needs. The Exceptions: Our premium models, Groenberg Alvar and Groenberg Tjelvar, come with an integrated lighting solution already installed for your convenience (dimmable LED light, USB port). Our Recommendation for all other models: To make your roof tent feel personal and cozy, we recommend using outdoor lamps or mobile fairy lights.
All the tools required to attach the roof tent to the roof rack are included.However, a ratchet spanner can make the work much easier.
Our T-Pegs pegs are suitable for all types of ground. Due to their special shape, they can also be hammered into hard ground.
