Solar control glass panel OKASOLAR W

low-esun protectiondouble-glazed

Product Overview
OKASOLAR W is a high-performance daylight system especially developed for the facade which combines the use of daylight with effective sun protection. Fixed louvres in the cavities direct daylight deeply into the room while ensuring excellent direction-selective sun and glare-protection. A further advantage of OKASOLAR W: the cooling loads and costs for artificial illumination can be significantly reduced and the energy balance of a building optimized.

Benefit

• Effective, direction-selective sun protection
• Daylight direction towards building interior
• Light transmission precisely and specifically adjustable to the project
• No limitations in the function when compared to shading systems located in the interior or exterior
• Embedding in a Multifunctional Modul (MFM) is possible
• Fire protection according to requirements
• Variety of special formats possible
• Visibility as bird protection function

Sustainability

• Daylight entry reduces need for artificial light
• Reduction of cooling load in summer, solar gains in winter time
• Fully recyclable
• Louvres fully and durably protected inside the cavity
• No additional cost for maintenance, repair or cleaning

User Comfort

• Comfortable daylight atmosphere in the entire interior
• Outstanding vision to the outside
• Effective privacy protection
