Rockwool Insulation (1000°C)

Rockwool insulation is a specialized mineral wool product crafted from basalt rock and recycled materials, designed for construction applications. Unlike traditional stone wool, this product features a unique fibrous structure, resulting from a precise melting and spinning manufacturing process. This differentiation enhances its insulation properties, making it particularly suitable for general building insulation and fire protection, as opposed to the more generic versions seen in various markets.

The composition of this insulation combines basalt rock with recycled materials, providing a robust material that excels in thermal and acoustic insulation. This engineered composition ensures the product achieves a density ranging from 50 to 80 kg/m³, delivering exceptional thermal resistance and sound attenuation. Its compressive strength of≥0.4 MPa adds to its durability, allowing it to endure physical stresses in diverse applications, including firebreak partitions and insulation for commercial and industrial spaces.

In service, rockwool insulation exhibits remarkable performance characteristics, operating effectively at temperature limits reaching 1000°C. With low thermal conductivity, it minimizes heat loss, contributing to overall energy efficiency for systems reliant on thermal management. Such properties make it an indispensable choice for environments demanding stringent safety regulations and dependable heat resistance, thereby enhancing the performance of adjacent equipment in high-heat situations.

This product is available in manageable roll formats, wrapped securely in protective plastic for shipping. Standard dimensions of 1200mm by 3000mm rolls come with the option for custom lengths to fulfill specific project needs. Clients are encouraged to confirm thickness requirements, ranging from 50mm to 100mm, before placing an order. Zenco Systems Ltd ensures consistent supply from its base in Nairobi, facilitating dependable service across East Africa.

Rockwool insulation is made from basalt rock combined with recycled materials, distinguishing it from the pure stone fibre used in Zenco's rockwool blanket and board lines, and it's tested to the European EN 13162 standard rather than the ASTM standards that govern our other rockwool products — a reflection of its broader orientation toward general building and construction insulation rather than industrial-only duty. Buyers specify it for boiler shell lagging, furnace insulation, hot water pipe insulation, HVAC duct wrap, firebreak partitions, soundproofing walls, industrial equipment insulation, pipe wrapping, roof insulation, wall cavity insulation, external wall systems, fire doors and frames, industrial ovens, and even commercial kitchen and restaurant insulation — spanning construction, manufacturing, power generation, petrochemical, food processing, cement, glass production, and steel industries. It's also known by generic names — mineral wool, rock wool, stone wool, or RW — describing the same basalt-fibre material class across manufacturers. It's supplied as 1200mm x 3000mm rolls wrapped in protective plastic and shipped on pallets, with custom lengths available on request and cartons for bulk orders. Rated to 1000°C with a ≥0.4 MPa compressive strength and 0.040 W/m·K conductivity, it sits between Zenco's rockwool blanket and board on most figures, making it a genuinely flexible choice for buyers whose job spans both industrial pipe-lagging and general building insulation on the same site. Secure using stainless steel anchors and ensure overlaps during installation, tested to EN 13162 — an insufficient overlap at roll joints is the most common cause of cold bridging on wall and roof applications. We supply it to buyers across Kenya and East Africa, for both industrial contractors and general construction firms — send your roll count and length requirement for a quotation.
