OKASOLAR F Insulating Glass with Integral Sun Control Louvres

INFOTEXT OKASOLAR F Glazing with Integral Sun Control Louvres OKASOLAR F is an insulating glass with fixed louvres in the cavity between the glass panes. OKASOLAR F enables both the use of daylight as well as an effective solar control, and has been optimised for use in the façade. For roof glazing, we recommend our product OKASOLAR S. With its three-dimensionally shaped, highly reflective profile, OKASOLAR F offers: • • • • • • Efficient directionally selective solar control Directionally selective light transmission Partial through-vision Two different louvre types (O and U), which can be combined in one element. Can be easily recycled Visibility for birds Physical properties Thermal insulation OKASOLAR F is available as a 2-pane make-up with cavity between the panes of 16 mm, and also as a 3-pane make-up with an additional cavity between the panes. Depending on the gas filling and coating, the 2-pane make-up achieves Ug values ≥ 1.1 W/(m²K). As a 3pane make-up, Ug values ≥ 0.6 W/(m²K) are possible. Sound insulation The integrated louvres have no significant effect on the sound insulation. The achievable values depend on the glass assembly. Spectral properties The compact louvre cross-section permits horizontal through-vision on a proportional area of approx. 57%. Type U has been primarily optimized for glare protection and reflection of light outwards (retroreflection). Type O has a special profile shape, which deflects daylight into the room. Therefore, O type is especially suited for skylights in vertical facades and for the area above approx. 1800 mm from the finished floor level in ceiling-high glazing, in order to avoid glare from the light deflected inwards. The function of OKASOLAR F depends on the current radiation conditions. Partial trough-vision is always given, despite the solar control which differs depending on the season and time of day.

INFOTEXT Integrated in a vertical façade, OKASOLAR F functions as follows: 1. direct irradiation from high and medium solar altitude • thermal solar control with a low total solar energy transmittance as ≥ 9 %, in particular secondary heat transfer with low solar radiation transmission • glare protection • light deflected into the room with type O 2. direct irradiation from low solar altitude • partial transmission of the direct sunlight • light deflected into the room with type O 3.diffused irradiation (overcast sky) • preferred light transmission flat in every part of the room Technical...

INFOTEXT The specified values may change as a result of technical developments. No guarantee is therefore given for their correctness. Make-up The special feature of OKASOLAR F is that the louvres for solar control and use of daylight are integrated in the cavity between the glass and therefore pose no special requirements concerning the installation, maintenance and cleaning. In fact, the OKASOLAR element can be treated like conventional insulating glass. The glass thickness and type are based on the structural needs and constructional requirements. Standard make-up: 2-pane make-up...

INFOTEXT The maximum area is 7 m2. Special shapes are possible. The feasibility and divisions must be discussed with OKALUX beforehand. It may be necessary to use an increased secondary sealant in the case of smaller dimensions and/or greater thickness of glass. The required edge seal width must be discussed with OKALUX beforehand. In the case of over sized units, joints could occur at the edge and joint profiles. OKALUX will specify the location of the joints. For tolerance reasons and due to differing temperature expansion, the insert may be exhibit an expansion gap of up to 2.0 mm on...

INFOTEXT Installation instructions OKASOLAR insulating glass is glazed as per normal insulating glass. During transportation, the insert may slide to the side, creating a greater visible slit between the spacer and the insert or the support profiles could become inclined. We must be notified in writing beforehand of any special loads which may occur during transportation (vibrations/shaking). For instructions and recommendations for the installation of our insulating glazing, please refer to our information and instructions for customers contained in "Delivery of OKALUX Glass Products" and...
