STONEWOOL LRB - ROCK WOOL by NIKHIL ENTERPRISES is an advanced fireproof, acoustic, and thermal insulation solution crafted from basalt rock. Manufactured under the reputed Sunrock Brand, these Lightly Resin Bonded (LRB) mattresses are made by spinning molten basalt at high speeds into fine fibers and bonding them using high-quality thermosetting resins. The product features flexible, lightweight, and resilient characteristics due to its low resin and VOC content, making it eco-friendly and ideal for extreme high-temperature applications up to 750°C. STONEWOOL LRB mattresses are reinforced with GI or SS hexagonal wire mesh on one or both sides based on client specifications. These mattresses conform to IS 8183:1993 and ASTM C 592 standards with various thickness and density options available for optimal insulation performance. They are excellently suited for insulating boilers, ducts, ovens, furnaces, pipelines, and chimney walls where fire resistance, durability, and adaptability to curved surfaces are critical.
