Common Questions & Answers

How does a Lumina tunnel perform at sunset or sunrise times?

  • Lumina “Max Lighting” accessory can increase the solar capture when the sun goes down (winter solstice) and at sunrise and sunset.
  • Lumina Aluminum tunnel/tube has a special highly reflective inner coating (almost perfect mirror), reflecting 99.7% of the sunlight, sending it to the inside of the building.

What material is the dome made of?

The external pyramid is made of Polycarbonate that is highly transparent, lightweight, high impact-resistant, and has excellent insulation both sound and heat.

What are the benefits of daylight?

Daylight is always associated with improved mood, enhanced morale, and less fatigue. Studies suggest that environments with natural light have a direct impact on increasing the productivity and satisfaction of students and employees. Moreover, introducing daylight into your building will reduce the amount of artificial light decreasing your electricity cost from 15 to 40 percent.

What are the advantages of polycarbonate against the glass?

Polycarbonate sheets have 200 times more impact resistance than glass, being virtually unbreakable while weighing half of the weight. Multiwall sheets are more than 85% lighter than glass having up to 60% better heat insulation hence allowing the reduction of the structural requirements of buildings.

Polycarbonate will never shatter, and it is weather-resistant due to its co-extruded UV protection layer.

Polycarbonate offers excellent properties compared to glass in life expectancy, impact-resistant, lightweight, heat insulation, and maneuvering.
