Capillary System with White Capillary Slabs

KAPILUX W light-diffusing insulating glass offer numerous advantages: The transparent capillary slabs in the cavity allow for an even and shadow-free illumination with daylight deep into the room. The sun and glare-protection are very good, and the heat insulation is improved by the capillary tubes. The transmission values can be individually adjusted to the requirements.

What makes it different from KAPILUX T with transparent capillaries is that these are colored white in KAPILUX W, thus satisfying increased requirements on sun and glare-protection.
