Industrial curtain wall panel serves as building outer enclosure decoration and insulation component bearing wind rain ultraviolet long term erosion. Unqualified curtain wall panel will fade warp leak water or lose fire resistance within short service time. Many industrial park construction teams only focus surface appearance ignoring hidden technical indexes triggering later exterior wall renovation cost. This article sorts mandatory technical standards for qualified industrial curtain wall panel.
Curtain Wall Panel Weather Resistance Coating Standard Qualified industrial curtain wall panel adopts fluorocarbon surface coating resisting ultraviolet radiation over twenty years without color fading or powder peeling. Ordinary polyester coating only maintains three to five years anti fading effect unsuitable outdoor long term exposure environment. The coating thickness reaches thirty micrometers above to block acid rain sea salt fog corrosion for coastal industrial park buildings and extend panel service cycle largely.
Curtain Wall Panel Fire Insulation Core Index Industrial curtain wall panel core must match factory fire risk classification. Chemical manufacturing park curtain wall uses rock wool core A grade fire resistant curtain wall panel. General light industry factory selects B1 grade PIR core curtain wall balancing insulation and cost. Thin foam core curtain wall without flame retardant treatment cannot pass industrial building fire acceptance and will be forced to replace after inspection.
Curtain Wall Panel Flatness And Anti Deformation Standard Curtain wall panel surface flatness deviation must be controlled below one millimeter per meter to avoid uneven exterior wall visual effect. The composite sandwich structure adds reinforcing ribs inside to resist strong wind pressure seasonal temperature expansion and contraction deformation. Large span outer wall curtain wall adopts thickened metal surface sheet to prevent bulging concave surface phenomenon after long term outdoor use to keep neat building facade aesthetic effect.
Curtain Wall Panel Sealing Waterproof Technical Requirement Interlocking edge design and matched rubber sealing strip form multi channel waterproof barrier for curtain wall panel splicing gaps. Single glue filling sealing easily aging crack leading wall seepage under heavy rain. Qualified industrial curtain wall system adds hidden drainage groove inside panel joint to discharge residual rainwater without penetrating indoor workshop space and avoid wall internal insulation material damp failure.
