Key Considerations for Outdoor Pipe Insulation

UV resistance — standard black Armaflex degrades in sunlight without protection

Temperature rating — solar pipes can reach 120°C+, requiring HT-grade insulation

Weatherproofing — joints must be sealed to prevent moisture ingress

Frost protection — adequate wall thickness is critical for unheated outdoor pipes
