Frequently asked questions
Permits and authorizations to be able to install a pressure balloon may vary depending on the municipality in which it is located, as there is currently no precise regulation valid throughout the country. The only text on the subject is Art. 13 of Ministerial Decree 18/03/1996 et seq. m.
If a sports activity is carried out indoors, inside pressostatic structures, and there are no attached service areas, it is neither a “sports facility” nor a “sports complex” as defined by Ministerial Decree March 18, 1996, and therefore is not included, regardless of area, in item 65 of Annex I to Presidential Decree 151/2011). In cases where the public is expected to be present, the above activity will be subject to fire department inspections if the capacity is more than 100 people.

Spaces exclusively dedicated to sports activities, as defined by the Ministerial Decree of March 18, 1996, even if they are indoors and have a gross floor area of more than 200 square meters, are exempt from the requirements established by the aforementioned Presidential Decree. Said activities will still have to comply, under their own responsibility, with the applicable fire prevention regulations.

In case of snow, it is advisable to maintain an overpressure of at least 20 mm water column (unit of air pressure) inside the balloon. This can be done by closing the air calibration lever, located on the recirculation of the generator. If this is not sufficient, it will be necessary to manually activate the emergency unit. Two other useful tips are to turn on the heating system and set it at a constant temperature of at least 17 C° and to turn off all hot air destratification systems (destratifier fan) if present, to allow the hot air to rise and stratify over the top of the canopy, thus facilitating the melting of the snow present on the top of the balloon and preventing its accumulation.
To keep your Prima srl balloon beautiful and functional all you need to do is to perform a few simple checks periodically, some of which may vary depending on the type of pressostatic cover you choose (single membrane, double membrane, “Class A”), as per the appropriate use and maintenance manual that we will provide with the pressostatic balloon itself.
Theoretically, the average lifespan of a pressure balloon is around 20 years. Obviously, it is then necessary to evaluate on a case-by-case basis according to the constancy applied by the plant operators in carrying out routine maintenance, compliance with the rules for the good preservation of the roof, the professionalism of the personnel used for seasonal assembly/disassembly as well as whether the place chosen for the seasonal sheltering of the disassembled sheet is congruous to preserve its integrity.
Cleaning Your Prima Srl Pressure Balloon can be done with water and neutral, nonfoaming soap or detergent, provided the latter is abradant-free; the concentration of detergent in the water and the temperature should be chosen according to the type of dirt. Brushes with soft bristles are indicated. Avoid the use of solvents and/or hydrocarbons for grease stains. After thorough washing with detergent take care to rinse with water to remove all traces of detergent. Do the last rinse with 1% solution of common hypochlorite in water. Finally dry the whole surface perfectly with soft cloth.
Absolutely not. Despite what one may mistakenly be led to think, the air pressure inside the balloon that enables its sustenance is imperceptible to human beings. Inside the pressostatic cover also the air changes required by Law, i.e. 3 air changes per hour, are guaranteed through the air generator.
No special permission is required to replace your old roofing membrane on a fixed structure with a new membrane, provided that you do not change the type of fabric used and therefore the weight of the membrane is the same as that indicated in the initial design of the structure.
