2. Lledó Energía
CARACTERISTICS:
• High performance prismatic daylighting sistems
• Thermal isulation frames
• Maximum light transmision with 100% difussion
• Illuminates larger areas for a greater number of hours per day, reducing
power consumption by optimizing the lighting
• 3 Glazing options:
– Simple
– Doble
– Triple
• Regulating the entry of light: the possibility of adding blades and automatic
lighting control to control the amount of natural light input

5. Lledó Energía
ADVANTAGES
Provides a light transmission than other conventional skylights by 35% and a
reflection-free spread 100%
Eliminates damage caused by direct sunlight
Prevents damage from UV radiation indoors
Double, triple and even quadruple glazing for superior isolation
Thermal insulation
Completely sealed corners that do not allow moisture penetration
High quality lenses
Contain thousands of tiny prisms
The prisms produce the refraction of sunlight, spreading the bright sunlight
through space
As there is no direct sunlight, there is no danger of "hot spots"
