Discover RadiantGUARD Xtreme, a premium radiant barrier roll designed for attics and exterior walls. This perforated, double-reflective aluminum insulation is built to resist tearing while delivering strong performance. It meets and exceeds ASTM C1313 radiant barrier certification, with documented test results covering surface emittance, water vapor transmission, flame characteristics, corrosivity, tear resistance, and adhesive performance. The certification documentation is visible in product photos, highlighting its Class A / Class 1 fire rating and alignment with common building codes.

Strong performance and practicality

• Blocks up to 95% of radiant heat transfer, helping to keep attic temperatures steadier and indoor comfort more consistent.
• Heavy-duty construction at 28 lbs per roll offers a robust barrier that resists tears and punctures, promoting long-term reliability.
• Perforated design supports breathability while maintaining effective insulation performance.

In real-world terms, this insulation option can contribute to cooler attic temps—potentially around a 30-degree drop in hot climates—while supporting more stable cooling needs year-round. The roll is designed for straightforward DIY installation, without the need for specialized equipment.

• DIY installation: staple the foil to the underside of attic roof rafters, and extend coverage to vertical exterior walls (gable walls) for a complete barrier between indoors and outdoors.
• Easy to cut and shape: the entire roll can be sliced with common tools such as utility scissors or a hacksaw.
• Non-toxic, non-carcinogenic, fiber-free, and maintenance-free, reducing handling concerns compared with some alternative methods.

These attributes collectively mean you’re looking at a practical, high-quality option that aligns with standard building practices and safety expectations. While results can vary by home and climate, RadiantGUARD Xtreme is positioned as a durable, high-performance barrier designed to support energy efficiency and consistent comfort without requiring special protective gear during installation.
