Original Attic Radiant Barrier - 26 Wide / 1000 sq ft, Tearproof Perforated/Breathable Double-Sided Pure Aluminum Foil Insulation + Free Tape,...

The Authentic DIY Radiant Barrier Foil! Tear-resistant, commercial-grade material - prepared for installation. Lower attic temperatures by as much as 30 degrees. Seam tape provided at no extra cost. We exclusively utilize PURE Aluminum Foil that is Double Sided. We decline to use lower-quality metalized plastic film products employed by numerous competitors, which resemble a potato chip bag. These substandard products will deteriorate over time in a hot attic. THIS distinguishes 97% reflectivity from 95% reflectivity. Perforated includes tiny holes to permit moisture to pass through. This reflective insulation is NOT a vapor barrier. A vapor barrier in your attic can trap moisture, potentially leading to air quality concerns, which is undesirable. All products feature an internal tear-resistant tarp-like fabric. Multiple Sizes: Offered in 26 and 48 widths. The 26 size is ideal to run vertically (up/down) in truss-style attics. The 48 roll is ideal to run horizontally (left/right) in standard open-frame attics
