新西兰采购需求：吸音天花板挡板、吸音吊顶板、云形天花板、悬挂式吸音挡板、六角形吊顶、垂直吊顶

I'm looking for acoustic panels for a 1800 sqm ceiling project in New Zealand. My aim is to find a solution that serves both as a decorative ceiling finish and provides insulation against the iron roof above. I'm particularly interested in options with a minimum thickness of 70mm to ensure effective sound absorption and thermal regulation. In terms of aesthetics, it's essential that the panels look appealing and complement the overall design of the space. I'd love to see your available options, including any unique designs or finishes you might offer. Please provide details on materials, colors, and any customization possibilities to help me make an informed decision.
