Adopting 35.3mm wide multi-cavity thermal insulation strips, combined with the frame's six-cavity structure and vertical isotherm design. Meanwhile, the strip-penetrating positions are standard equipped with sound insulation cotton filling, which not only further enhances thermal insulation and soundproofing performance but also effectively prevents water seepage at the strip-penetrating positions.

The corner connectors are one-piece die-cast aluminum alloy glue-injection corner brackets + integrated aluminum alloy glue-injection corner brackets. The optimized design of the glue injection slots ensures more sufficient glue flow and higher corner strength.

The fixed pressing lines are 45-degree spliced square full-frame pressing lines, which are elegant in appearance and safer for large glass installations.
