A2 THERMOBUBBLE insulation product consists of a PE layer containing air cells with diameter of ø=10mm, both sides covered with 10-12 µm aluminium films. The aluminium films reflect heat radiation while the air bubbles resist heat conduction and convection as well as act as a sound barrier. A2 THERMOBUBBLE is sound reduction & heat insulation material with high-strength, good tear resistance, waterproof, nonflammable, and preventing fire spread. The aluminum membrane has been treated with anti-oxidation process and can sustain different weather conditions.
