The Difference Between Thermal Conduction and Radiant Heat
Over 90% of heat entering a metal-roofed industrial shed travels via thermal radiation (infrared wavelengths emitted by the sun-baked metal skin). Conventional mass insulations such as glass wool or rock wool are designed primarily to slow down conduction, whereas radiant barrier bubble insulations stop heat before it ever enters the building interior.
Why Dual-Sided Aluminum Bubble Insulation Excels
- 97% Radiant Heat Block: High-purity polished aluminum surfaces reflect up to 97% of downward thermal radiation back through the roof cladding.
- Zero Fiber Shedding: Unlike glass wool which releases microscopic glass fibers into the plant workspace causing skin and lung irritation, bubble insulation is clean, fiber-free, and safe for food-processing and pharmaceutical warehousing.
- Moisture & Vapor Barrier: Trapped air bubbles sealed inside polyethylene layers act as a 100% moisture barrier, completely eliminating roof condensation droplets during winter cycles.
- Rapid Installation: Lightweight rolls install directly across purlins ahead of sheet laying with 40% less labor time.
For modern industrial facilities, pairing Greater™ Profile Sheets with Greater™ Double Bubble Thermal Insulation provides the ultimate energy-efficient building envelope.
