Knauf Insulation's Rock Stars

Following a multimillion-pound investment, Knauf Insulation has rebranded its versatile Rocksil® Rock Mineral Wool range of insulation products.

The new brand, Rocksilk® Rock Mineral Wool Insulation, builds on the success of its predecessor, offering improvements throughout the line-up with exciting new products and a new packaging and delivery system.

Rock mineral wool has never sounded so good – “Rock solid performance, silk smooth result” – what a difference a ‘k’ makes!

The recent investment at Knauf Insulation’s rock mineral wool production facility at Queensferry in North Wales was a major one. All parts of the production line have been either replaced or upgraded, allowing capacity to increase to 33,000 tonnes per year, significant advances in material and product development and the introduction of some exciting new products. New, state-of-the-art fiberisation equipment at the ‘hot end’ of the process has enabled very high quality fibres to be produced, enhancing the material’s qualities, improving its look and feel and resulting in new products such as Rocksilk® Flexible Slab. Equipment using KrimpactTM Technology, an advanced manufacturing technique that aligns the fibres formed during manufacture, has also been installed.

This has lead to the creation of new, high-strength, impact resistant materials with uniform density and consistent performance characteristics: two shining examples of the new products now available being Rocksilk® KrimpactTM Flat Roof Slabs and Rocksilk® KrimpactTM Facade Slab. Following its successful launch with Crown® Glass Mineral Wool products last year, Knauf Insulation’s compression packaging and Supakube® unitised delivery system have also been installed at Queensferry. Individual products are lightly compressed into durable polypropylene sleeves – giving up to 30% more product per pack – before being palletised and stretch-wrapped on non-returnable pallets.

The popular Supakube® system provides significant benefits throughout the supply chain: more product per delivery; loading, unloading and handling is more efficient; less storage space is required and, being weatherproof, Supakubes® can be stored outside – all of which add up to less handling and storage costs. The stock management system has also benefited and now allows mixed rock and glass mineral wool orders to be placed and urgent orders to be fulfilled within 24 hours. To support the range of Rocksilk® Insulation products, Knauf Insulation has produced a new brochure giving an overview of rock mineral wool, its benefits and uses. Rock mineral wool is a versatile insulation material, justifiably well known for having excellent thermal, acoustic and fire insulation properties.

Product specific brochures and datasheets are available via Knauf Insulation’s enquiries hotline or website.

The company’s dedicated Specification Sales Teams are active in the market to provide advice and marketing support to specifiers, distributors and users and the Technical Advisory Centre is, as always, on hand to answer technical questions about the product and its application.

As the manufacturer and supplier of three types of insulation material – Rocksilk® Rock Mineral Wool Insulation, Crown® Glass Mineral Wool Insulation and Polyfoam® Extruded Polystyrene (XPS) Insulation – Knauf Insulation are in a unique position in the market. With no, one, specific type of insulation material to support, Knauf Insulation are totally impartial in their advice – the insulation solution they recommend is The Best Solution that can be recommended.
