Star · Nebula 103 Double Inward-opening Low Energy Sound Insulation Window Manufacturer

SCHÜPARD presents the Star・Nebula 103 Series Thermal Break Aluminum Double Inward Side-Mount Screen Integrated Casement Window. As a specialized premium energy-saving screen-integrated window manufacturer, we design this series for extreme thermal insulation and noise reduction. The frame width measures 103mm with double inward side-mounted profile design. The aluminum profile has a thickness of 2.0mm. This heavy-duty specification ensures the window remains rigid and durable under complex high-noise and temperature difference weather conditions.

The glazing system focuses on thermal and acoustic insulation. The unit features Nanbo double tempered glass filled with argon gas. The configuration includes two 5mm glass sheets separated by an 18mm air gap (5mm+18A+5mm). A standard insulated spacer sits between the glass panes. We also use a 54mm ultra-wide multi-cavity polyamide fiber thermal break strip. This 4-cavity aluminum screen-integrated casement window effectively reduces heat transfer with a U-value of 1.9 W/(m²・K).

Hardware components prioritize security and operation feel. The window utilizes Viehage handles, available in black or silver, alongside durable full-set multi-point locks and built-in high-transparency stainless steel insect mesh. For safety, the system includes metal R-corner anti-collision protection. Double inward opening design realizes ventilation and anti-mosquito function simultaneously, all operations finished indoors for easy cleaning and high-rise anti-falling safety.

This product meets premium international casement window standards. The Star・Nebula 103 Series holds CE and ISO9001 certifications with Grade 9 wind resistance. Optional customized packaging and various screen mesh styles are available upon request. The Star・Nebula 103 Series is a reliable top-tier choice for villa, high-rise apartment and street-side noise reduction residential projects requiring certified energy-saving screen-integrated aluminum windows.
