System Performance
Kapilux provides sun protection and transmits light uniformly into a room, independently of the light’s angle of incidence. This reduces glare considerably, as any bright area of light is spread so that a greater area is lit. The capillary structure of Kapilux has a high light permeability due to the light conduction properties of the tube arrangement. It is therefore largely independent of the slab thickness. The small cavities in the capillaries produce an insulating air cushion that stops most of the heat transport and therefore minimizes thermal losses due to convection. While the thickness of the slab is critical to improve the thermal properties of the system, it doesn’t affect its light diffusing performance. An insulating glass unit with Kapilux can be produced with 100% UV protection if necessary. Although light transmission can be as high as 90%, view thorugh the slab is obstructed by the acrylic inlet. For a more advanced lighting analysis and project specific results, we recommend using the Lightsolve program (under development).

System Description
Light-diffusing insulating panels are built-up using an insulating glass unit (IGU).The honeycomb structure within Kapilux’s slab is made of acrylic (PMMA). These short acrylic strips are connected on the two ends to a glass fiber mat, and then to the IGU glass panes. This creates a kind of sandwich of glass, glass fiber, acrylic, glass fiber and glass. The acrylic section can be any of a number of thicknesses, creating slabs of a total of 12, 16, 24, 32, or 40mm thick. The panes can be up to 3.5m long, and have similar maintenance requirements as for other insulating glass systems. |
