Glass Options
DECORATIVE AND SPECIALTY GLASS
TEMPERED GLASS

Tempered glass is a type of reinforced glass with 3-5 times the bending strength and 5-10 times the impact strength of ordinary glass. Our glass meets SGCC (USA) and AS2208 (Australia) standards. Its high load capacity makes it durable, and if broken, it shatters into small, harmless fragments for enhanced safety.

LOW-E GLASS

Low-E glass blocks infrared light from outside while retaining indoor heating and cooling energy, significantly improving energy efficiency and reducing HVAC costs. Our NFRC-certified Low-E options meet various SHGC and U-factor requirements for optimal performance.

WARM EDGE SPACERS

The spacer between glazing panes significantly impacts performance. Aluminum spacers, the standard choice, conduct heat 4,000-5,000 times more than insulation, causing edge condensation even in double glazing. Upgrading to warm edge spacers eliminates this weak point, improving thermal efficiency and preventing window crying.

LAMINATED GLASS

Laminated glass consists of two glass plies bonded with interlayers, creating a strong, uniform layer that holds together even when broken. Available in various thicknesses, it can incorporate coatings for insulation or low emissions. For specialized needs, PVB or SGP interlayers provide enhanced protection, including hurricane and bullet resistance.

FAQs
  • Q
    What hardware brands are available? What is the expected service life?

    We primarily partner with top European system hardware brands such as German G-U, SIEGENIA, and ROTO. These components undergo rigorous testing and, with normal use and maintenance, can achieve over 25,000 operating cycles (approximately 15-20 years service life).

  • Q
    What advantages do outward-opening windows have over other types of windows？

    When the entire sash opens outward, the full window opening is available for air exchange. This high-efficiency ventilation quickly removes stale air and moisture from the interior.

  • Q
    What are the advantages of the 68mm profile width compared with narrow profiles？

    The 68mm widened profile can accommodate thicker insulated glass, improving thermal and sound insulation effects. At the same time, the larger profile cavity can be equipped with stronger hardware, enhancing the load-bearing capacity of the sash, extending the service life of the hardware, and is suitable for the design and installation of large-size windows.

  • Q
    Does your factory conduct factory inspections for potential clients? And what is the process like?

    We warmly welcome and encourage customers to conduct factory inspections. This is the best way to build trust. Please inform us in advance of your plans. We will assist you in obtaining the invitation letter and arrange a dedicated team to receive you.
