OKALUX Capillary Daylighting

OKALUX Capillary Daylighting

OKALUX light-diffusing insulating glass offers numerous advantages: The capillary slab in the cavity allows for an even and shadow-free illumination with daylight deep into the room. The sun and glare-protection are very good, the heat insulation excellent and the transmission values individually adjustable to the requirements.

Thanks to a functional layer in combination with a gas-filled cavity for double- and triple-glazing build-ups, an optimized Ug-value can be achieved with the product variants OKALUX+ and OKALUX K.
