Silver Aluminium Spacer Bar

Traditional aluminum spacers require corner joints at the four corners. These four connection points are the weakest links in the seal, easily leading to air and water leakage over time, causing glass failure. Your high-frequency welded aluminum spacer, however, can be continuously bent to any angle, achieving seamless connections at the four corners. Eliminating the weakest connection point is equivalent to plugging the leakage gap at its source, greatly improving the edge sealing effect and thus significantly extending the lifespan of the entire glass pane.

The molecular sieve (desiccant) filled inside the aluminum spacer is crucial for absorbing moisture within the insulating layer. Poor quality aluminum strips or substandard processes will affect the activity of the molecular sieve. This high-quality, unbleached aluminum spacer bar ensures the molecular sieve maintains its water-absorbing activity for a long time, rapidly reducing humidity inside the cavity and preventing moisture from corroding the sealant, thus further protecting the sealing system of the insulated glass. In winter, the temperature near the window is definitely lower than in the middle of the glass. Even a little moisture can easily cause condensation at the silver aluminum spacer bar. But frankly speaking, for most ordinary households, unbleached aluminum spacers are simply "good enough." Unless you live in a particularly cold place or have an obsessive pursuit of energy efficiency, there's really no need to waste money for a slight improvement in thermal performance.

When choosing unbleached aluminum spacers, we prioritize the use of virgin aluminum material. Upon receiving the goods, first check the appearance; a completely silver-white finish without blackening, rust spots, or scratches indicates it's acceptable. Common sizes are 6A, 9A, 12A, and 15A, selected according to the gap size of the insulated glass. A standard spacer bar is five meters long. When choosing a silver aluminum spacer bar, pay close attention to the wall thickness. It should not be less than 0.22 mm; thinner materials are prone to warping and deformation during assembly. The small holes on the inside of the spacer bar should be neat and smooth, without burrs or blockages. This allows for effective water absorption when a desiccant is inserted, preventing fogging and water ingress into the glass later. For regular bulk glass orders, choose straight-bar splicing; for curved windows, opt for a bendable style. Comparing painted and coated spacer bars, unpainted aluminum and sealant adhere more firmly, preventing peeling and delamination issues, resulting in lower prices and better value. By focusing on materials, wall thickness, and workmanship, you can purchase durable spacer bars.
