Introdu\u00e7\u00e3o<\/strong><\/h1>\n\n\n\n

When selecting glazing and enclosure panels for engineering projects, buyers and designers often focus on two core functions: sound insulation<\/strong> e isolamento t\u00e9rmico<\/strong>. There are many panel options available on the market, including acrylic sheet, tempered glass, color steel panel, FRP, and widely used Chapa de PC (chapa de policarbonato)<\/strong>. The difference in sound and heat insulation performance between different materials is quite large.<\/p>\n\n\n\n

Most buyers can only find scattered data online, without real-world test results. Many manufacturers only publish ideal lab data. Once installed on construction sites, factories or greenhouses, the actual performance may not match the marketing data.<\/p>\n\n\n\n

In this article, we will carry out PC sheet sound insulation and thermal insulation basic performance test analysis<\/strong>. We will explain the working principle of solid polycarbonate sheet<\/a><\/strong>\u00a0e multiwall polycarbonate sheet<\/strong>\u00a0for noise blocking and heat preservation, share groups of practical test data, compare how thickness, panel structure and installation methods affect PC sheet sound insulation effect<\/strong>\u00a0e PC sheet thermal insulation performance<\/strong>. We will also sort out key factors that affect test readings, correct common industry misunderstandings, and guide you to select suitable Folha de PC<\/strong>\u00a0according to your on-site noise level and local temperature difference.<\/p>\n\n\n\n

As an experienced manufacturer specializing in PC sheet fabrication<\/strong>, Yucheng<\/strong> BoardIndustry<\/strong>\u00a0provides custom processing service for solid PC sheet and<\/strong> multiwall polycarbonate sheet<\/a><\/strong>. A large number of our projects require both daylighting, sound insulation and thermal insulation. During project delivery, we completed dozens of field tests, covering factory noise reduction, greenhouse heat preservation, station canopy, rail transit noise barrier, equipment protective cover and building skylight projects. We do not merely sell finished Folha de PC<\/strong>. We can recommend proper panel thickness and structure according to your site noise data and climate temperature difference. We also provide cutting, bending, drilling, film coating and OEM one-stop processing service, solving all kinds of Folha de PC<\/strong>\u00a0application challenges.<\/p>\n\n\n\n

1. What is PC sheet? Difference between solid polycarbonate sheet and multiwall polycarbonate sheet<\/strong><\/strong><\/h2>\n\n\n\n
\"solid<\/figure>\n\n\n\n

To understand test results of PC sheet sound insulation and thermal insulation<\/strong>, you need to tell apart two mainstream Folha de PC<\/strong> types: solid polycarbonate solid sheet<\/strong> and hollow multiwall polycarbonate sheet<\/strong>. Their internal structures are totally different, which leads to huge difference in sound and heat insulation performance. This is the top reason for wrong material selection in many projects.<\/p>\n\n\n\n

Folha de PC<\/strong>, full name chapa de policarbonato<\/strong>, is engineering plastic panel extruded from polycarbonate resin. It features high toughness, impact resistance and weather resistance.<\/p>\n\n\n\n

    \n
  1. Solid polycarbonate sheet<\/strong>: monolithic solid structure without hollow air cavities. Available thickness covers 1.5mm,2mm,3mm,5mm,6mm,8mm,10mm,12mm,15mm,20mm. Solid structure delivers high impact strength and better sound insulation, while thermal insulation is weaker than multiwall polycarbonate sheet\u00a0with equal total thickness.<\/li>\n\n\n\n
  2. Multiwall polycarbonate sheet<\/strong>: internal ribs form one or multiple hollow air chambers, including double-wall, triple-wall, four-wall structure. Static air trapped inside hollow cavities acts as natural thermal barrier, so multiwall polycarbonate sheet<\/strong>\u00a0thermal insulation performance<\/strong>\u00a0is outstanding. However, hollow structure shows weaker performance blocking mid-to-high frequency noise compared with solid polycarbonate sheet with the same total thickness.<\/li>\n<\/ol>\n\n\n\n

    Key reminder: Many purchasers only check total thickness without checking panel structure. A 10mm solid PC sheet and a 10mm double-wall multiwall polycarbonate sheet show completely different sound insulation and thermal insulation test results<\/strong>, and they cannot replace each other directly.<\/p>\n\n\n\n

    Yucheng<\/strong> Board Industry<\/strong>\u00a0supplies solid chapa de policarbonato<\/strong>\u00a0and multiwall chapa de policarbonato<\/strong>\u00a0as required. Our panels can be co-extruded with UV coating for outdoor anti-aging. We also provide cutting, thermoforming, grooving, drilling and sealing processing. For noise barrier or thermal insulation daylighting projects, customers can provide drawings, and we finish full Folha de PC<\/strong>\u00a0fabrication so panels can be assembled directly on construction site.<\/p>\n\n\n\n

    2. Basic theory of PC sheet sound insulation: what is measured in sound test<\/strong><\/strong><\/h2>\n\n\n\n

    2.1 Two noise transmission paths<\/strong><\/strong><\/h3>\n\n\n\n

    Sound transmits in two ways: airborne sound and structure-borne sound. In PC sheet sound insulation test<\/strong>, most tests focus on airborne sound insulation<\/strong>, such as traffic noise, fan noise and outdoor human voice travelling through air.<\/p>\n\n\n\n
