Frequently asked questions about geodesic domes
What is the advantage of the Solardome geodesic dome shape?
Geodesic domes are aerodynamic, wind resistant and enormously strong. They also have superior air circulation compared to traditional square buildings.
What are Solardome geodesic domes made of?
Solardomes for growing schools are made from non corrosive aluminium components and 4mm toughened glass. Domes have a powder coated finish to all exterior surfaces and all fittings are made with stainless steel to prevent moss build up. The domes are greater than 98% recyclable.
What do schools use a dome for?
As a general outdoor classroom or growing space — although most are used for multidisciplinary activities. General subjects and activities that the dome can be used for are:
- Mathematics — basic geometry lessons.
- Science — growing plants, doing basic experiments in the dome, Chemical and Biological reactions, ecology and environmental studies
- Design technology — inspiring students to design and build some bedding areas in the dome
- Art — drawing the dome or plants in it or using it as a gallery to display artwork.
- Food technology — teaching about growing food, food waste recycling and healthy living - by growing and fertilizing your own fruit, herbs and vegetables
- Geography — ecology and sustainability
Why is a Solardome geodesic dome better for growing plants?
It provides optimum light transmission, heat retention and superb ventilation, reducing temperature differential. The geodesic shape is the perfect shape for growing plants.
How many pupils will fit in a dome?
It depends on how the Solardome is used. If it is filled with greenhouse staging units/ work stations around the outside of the dome then the capacity would be roughly as shown below:
- Agena (15ft/4.52m) — up to 15 pupils (seating only, 25)
- Capella (20ft/6.11m) — up to 25 pupils (seating only, 50)
- Vega (25ft/7.75m) — roughly 35 pupils (seating only, up to 70)
- Sirius (32ft/10m) — up to 60 pupils (seating only, up to 130)
Do I need planning permission or building regulations for a Solardome geodesic dome?
No planning permission is required in the UK for any of our domes, under normal circumstances and if built further than 5metres from a building. If closer than 5metres it is classed as an extension and standard allowances apply. However, if your School is a listed building, in an area of outstanding natural beauty or a conservation area, you will need to check with your local planning office.
Do you have to get Solardome to assemble the dome for your School?
You can either get us to build your dome on site once your base has been completed or you can get local contractors to build it for you.
Do you need a solid base or foundations for a Solardome?
For longevity it is recommended to put the dome on a solid, level base of: concrete, brick work or patio slabs. At a minimum there must be a level solid base under the circumference of the dome's foundation plates.
It is a good idea to have a couple of drainage holes built in to it, i.e. drain pipes set into the concrete.
If required, put in electricity cables and water pipes under the base when it is being built.
Is it easy to enter a Solardome geodesic dome in a wheelchair?
Yes. The entry has a very low sill which allows easy access for wheelchairs or wheelbarrows etc.
Do I need toughened glass/do the panes break easily?
All Solardomes for growing schools have 4mm toughened glass as standard. Panes of glass rarely break, even in high winds, due to the unique way the glass is held in the triangles and is never under tension.
Can I have other forms of glass?
You can get any 4mm section i.e. obscured styppolite glass, acrylic, or solid polycarbonate; we can also provide a UV reflective film to go over sections of the glass if required.
Do the domes get really hot in summer?
Not if all the ventilation is being used. Ventilation is at base, mid and roof levels. When all of the ventilation is open, the maximum difference in temperature between inside and out is about 5-7°C. To aid this we recommend domes have the maximum of five roof vents.
Do Solardomes stay warm in winter?
Yes in winter close down the windows and the dome will heat up several degrees, especially when it is very cold but the sun is out. However, you may need a fan heater for the winter on cloudy days if you are using it to grow tropical plants. Most schools put electricity under the ground when they do the base to allow for appliances in the dome.
Is it water proof?
If sealed properly around the nodal points when erecting the dome it will be water tight.
Will it get condensation?
It is designed to be an outdoor room and is single glazed so condensation will collect inside if the windows are shut and there is no heating. This might occasionally drip in the dome. However, once the ventilation is opened (especially roof vents) the dome will clear extremely quickly.
How long will a Solardome last?
Solardomes have been in production for 40 years and the original models are nearly all still going strong. The current domes are made with non-corrosive materials and are virtually maintenance free. A Dome should last well over 30 years if looked after and can even be moved if necessary.
How do you clean them?
To keep them looking good it is recommended they are cleaned on the outside once a quarter. We recommend washing them with a telescopic pole with a window cleaning kit attached or a jet power wash and a ladder and mop.
Can I have extra doors and windows?
Yes, you can have up to 3 doors in a dome at a 72 degrees difference to each other. You can put up to 5 vents in the roof per dome and as many side windows as required.
Can I link domes?
Yes you can link two or more domes via the doorways. To link domes you will also need an additional door per dome. We currently link domes via a short glass and aluminium tunnel.
Can I build it on a wall?
Yes, a small wall but it would need to be wide enough for the base plates to sit on (refer to site prep info). It is advisable to only have one door if it is on a wall.
Is funding available for Solardomes?
There are a number of funding sources available for school projects. Please see our funding section for more details.
