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

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 prismsThe prisms produce the refraction of sunlight, spreading the bright sunlight through spaceAs there is no direct sunlight, there is no danger of "hot spots"
