Used membrane covering, we made as a double layer with air cushion between layers. Double PVC layer is a very good thermal insulator in winter (air void insulates hall against frost penetration) and summer conditions (insulation against sunlight rays limits hall’s heating).
Halls are equipped with the system of layers blowing that maintains the air pressure between layers that create the air cushion.
Auxiliary lighting by lights from the roof made of a milk membrane which perfectly transmits the light. Lights that are mounted in the roof are led along the hall in two strips and that is why they perfectly light the interior of the hall. This kind of light is dispersed. It does not dazzle and it perfectly illuminates the hall. Used lights are available within two strips at dimensions of 2.50m x 22.0m. This kind of auxiliary lighting allows playing without dummy auxiliary lighting during the day time.
Meta-halogen lamps, asymmetrically arranged, 400 W per each lamp, Philips brand projectors.
Furnace at appropriately selected heating power, air heater burned with furnace oil or natural gas (together with necessary instrumentation).
