INFOTEXT OKALUX Light Diffusing Insulating Glass The challenge for OKALUX Light Diffusing Insulating Glass: to make daylight useful. With the use of a translucent light diffusing capillary slab both sides covered with additional glass fibre tissues in the cavity, OKALUX achieves • optimum, uniform light transmittance into the room, irrespective of irradiation conditions • light transmission and total solar energy transmittance as required • very good colour rendering index • good heat insulation • UV protection as required • sound insulation as required • vision protection and glare protection • attractive appearance in daylight and in artificial light • bird friendly glaszing Physical properties Thermal insulation The capillaries reduce the heat transfer in the cavity between panes in terms of convection and heat radiation. The thicker the OKAPANE insert, therefore, the better the Ug value. For OKAPANE thicknesses of 24 mm and over, we recommend the use of our OKALUX EVO product, which enables Ug values of ≥ 1.3 W/(m²K) to be achieved. With the triple pane make (OKALUX K product variant) it is possible to achieve Ug values of ≥ 0.8 W/(m2K). The Ug value of insulating glass in accordance with DIN EN 673 or DIN EN 674 always relates to vertical installation. If the insulating glass is at an angle, e.g. as in roof glazing, the Ug value increases, because the rising convection level in the cavity. Insulating glass with a standard value of Ug = 1.1 W/(m²K) has an actual value of approx. 1.7 W/(m²K) if used for horizontal roof glazing. The capillary slab in the cavity between panes prevents convection, which means that the Ug value of OKALUX is constant whatever the installation position. For roof glazing, OKALUX glass with a 24 mm capillary slab achieves the same Ug value as insulating glass with a Ug of 1.1 W/(m²K).

Spectral properties The special light diffusing properties of the OKAPANE insert provide an optimised, uniform distribution of light in the room, regardless of irradiation conditions. The special geometry of the “OKAPANE” capillary material results in improved heat insulation with an increased thickness, but without any notable reduction in light transmission. The g value...

INFOTEXT Make-up What makes OKALUX light diffusing insulating glass so special is the capillary slab inserted in the cavity between the panes. The glass type and thickness vary according to static requirements and design requirements. Standard make-up: Outer pane additional glass fibre tissues Capillary slab 8 - 24 mm additional glass fibre tissues Inner pane Variations in the density of the capillary slab and the diameters of the capillaries may be visible, as can joints which are necessary for production reasons. Under certain light conditions it may also be possible that fine lines, also the...
