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). Thanks to the air cushion, hall’s layers are well-tensioned and they do not flutter in the wind.
The system of layers blowing that maintains the air pressure between layers that create the air cushion.
Lights made of milky membrane transmit light very well. They are installed in the roof and they are led in two strips. They perfectly light the hall. The light is dispersed, it does not dazzle and it evenly illuminate the hall; used lights are available within two strips at the width of 2.50 mper hall’s length; auxiliary lighting allows playing without dummy auxiliary light during the day time.
Meta-halogen lamps are asymmetrically arranged, power: 400 W per each, Philips brand projectors.
Furnace at appropriately selected heating power, air heater burned with furnace oil or natural gas together with necessary instrumentation.
