OKALUX™Light diffusing glass |  |
At a glance
Endless possibilities between two pieces of glass
The challenge for OKALUX™ light diffusing insulating glass: to make daylight useful. With a translucent capillary slab covered with glass fiber tissues in the cavity. OKALUX™ light diffusing insulating glass is installed like normal insulating glass. To cover the capillary structure, glass fiber tissue is fitted in the cavity on both sides.
- Shadowless light with true color rendition.
- Precise diffusion prevents glare while preserving a fine quality of light
- Stronger performance characteristics than ordinary insulated glass
- Panels laminated for safety glazing
- Flexibility in design: A variety of sizes and shapes accommodate ridges, eaves, valleys, joints, and other structural challenges
Key facts
- Precise diffusion prevents glare while preserving a fine quality of light
- Stronger performance characteristics than ordinary insulated glass
- Optimized for inclined roofs and overhead glazings; easy, unobstructed drainage
- Panels laminated for safety glazing
- Resistance to thermal stresses caused by climate heating systems and shading
- Flexibility in design: A variety of sizes and shapes accommodate ridges, eaves, valleys, joints, and other structural challenges

Heat and sound insulation
The capillaries prevent heat transmission in the cavity, not only with respect to convection, but also in terms of heat radiation. The particular geometry of “OKAPANE” capillary material means that an improvement in thermal insulation through greater layer thicknesses does not lead to any appreciable reduction in light transmission. In the new version
(product version “OKALUX-P”), U-values of up to 0.9 W/m2/K (0.16 BTU/hr/ft2/°F) can be achieved. Further synergies become apparent in the field of sound insulation. Capillary slabs uncouple the panes of the insulating glass and absorb the sound. The following information applies for build-ups with a 6 mm (~ 1/4") outer pane and a laminated glass inner
pane of 8 mm (~5/16").
Deflection of glass
The glass panes of hermetically sealed units will tend to deflect inward or
outward according to temperature changes due to varying air pressure
within the units. To minimize this effect, if possible the outer pane should
be stiffer and thicker than the inboard plane.
Dimensions
- Minimum size 50 cm x 50 cm (~20" x 20")
- Maximum size 123 cm x 400 cm (~48" x 157")
