Double P2 Double Bubble Double Foil

Product: Two plies of 0.32” durable air-bubble film laminated between either two layers of low-E reflective metalized foil (Double Foil). Solid, non-breathable vapor barrier. Standard rolls: 4'×75', 4'×125' or, 5' ×125' (≈ 300 / 500 / 625 ft² coverage). Emittance (foil side): E=0.05 (≈ 95% reflectivity). Class A / Class 1 fire rating. WVTR (ASTM E-96): ~0.02 perms. Mold/Mildew: No growth. General Description: Polyshield Double P2 is a double-bubble reflective insulation and vapor barrier engineered to combat summer heat gain and winter heat loss while reducing moisture condensation and blocking water vapor. The encapsulated air bubbles create a reliable thermal break to limit conductive heat transfer through the assembly. Double Foil delivers maximum reflectivity on both sides - ideal inside finished walls, roofs, and other concealed cavities that benefit from a reflective surface facing an air space. 2P2 is an excellent solution for a wide range of applications, from residential to co
