K-Flex Insul-Sheet® Closed cell Rubber Insulation Rolls

1/2" x 4' x 70' 3/4" x 4' x 50' 1" x 4' x 35'   K-Flex Insul-Sheet® Closed-Cell Rubber Insulation Rolls – Flexible, Durable, and Energy Efficient. The K-Flex Insul-Sheet® Closed-Cell Rubber Insulation Rolls are premium-quality, flexible elastomeric sheet insulation solutions designed to conserve energy, prevent condensation, and provide superior thermal protection for large pipes, ducts, tanks, vessels, and equipment. Its innovative closed-cell structure delivers exceptional thermal performance with a k-value of 0.245 at 75°F, while its water vapor transmission rate (WVT) of 0.03 perm-in ensures excellent resistance to moisture penetration. Engineered for use across a wide temperature range (-297°F to +220°F), this insulation is perfect for demanding industrial, commercial, or residential applications.  Unmatched Features of K-Flex Insul-Sheet® Insulation Rolls: Flexible and Durable Design: The closed-cell elastomeric construction ensures flexibility while maintaining durability for long-lasting performance. Double-Sided Protective Skin: A tough, easy-to-clean protective skin on both sides resists dirt, moisture, and wear. Either side can face outward, reducing waste if one surface gets damaged. Exceptional Thermal and Moisture Protection: Minimize heat loss or gain while effectively preventing condensation with its advanced thermal properties. EPA-Approved Antimicrobial Protection: Built-in antimicrobial agent guards against mold, fungi, and bacterial growth, ensuring safe and hygienic use.  Sustainability Certified: Insul-Sheet is GREENGUARD-certified for indoor air quality under the Children and Schools classification, and ASTM E84-rated (25/50) for fire safety up to 2” thickness. Temperature Range: Operates effectively between -297°F and +220°F. Thermal Properties: k-value of 0.245 at 75°F, WVT of 0.03 perm-in. Material: Non-porous, non-fibrous, closed-cell elastomeric structure with antimicrobial protection. Data Sheet Looking for something a little smaller? Link to Closed Cell Rubber Sheets
