Waterproof Light Trough
Polure waterproof light troughs enable continuous LED lighting installation in humid spa rooms, bathrooms, outdoor covered balconies, and kitchens. Manufactured from high-density rigid polyurethane (150-220 kg/m³), these LED profiles feature a closed-cell polymer core with less than 1% water absorption, ensuring total protection against steam, water splash, and mold growth. Thermally stable between -100 °C / +80 °C and rated B2 for fire safety, they arrive pre-coated with technical white acrylic primer. Installation mandates continuous PU assembly adhesive along all wall and ceiling contact edges, backed by mechanical countersunk screw attachment. Fill screw heads with facade putty and sand smooth before painting with appropriate moisture- or weather-resistant paint.
