Capillary System with Transparent Capillary Slabs

KAPILUX T light-diffusing insulating glass offers 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.

Characteristic for KAPILUX T is that the structure of the transparent capillary tubes is visible from both sides. The capillary inserts allow the product to meet high requirements on light transmission and sun protection. The build-up also allows for partial transparency creating the illusion of depth and a lively appearance.
