Do you need a more efficient thermal insulation? Air dome can be made with a DOUBLE MEMBRANE
In factory two membranes can be joined with high-frequency welders: the outer membrane is 700 gr/mq heavy and the inner one 500 gr/mq. While in use there's a gap between the two membranes where warm or cold air would dwell benefitting a more efficient thermal insulation from the outside temperature than a single membrane.
This solution is advised for swimming-pools or rigid cold places.
