Knauf Insulation’s hot HVAC range

Knauf Insulation’s recent multimillion-pound investment at its rock mineral wool production facility in Queensferry, North Wales, has strengthened its market leading range of HVAC insulation products. The range offers HVAC designers an impressive choice of pipe, slab and roll, mattress and lining products under the company’s well known, high-performance Crown® Glass Mineral Wool and Rocksilk® Rock Mineral Wool brands.

Knauf Insulation is one of the HVAC industry’s most experienced suppliers and has been manufacturing HVAC insulation products since the mid-1960s. Today, the company offers the widest choice of HVAC insulation products in the UK and supports the range with a strong package that includes a dedicated Non-residential Sales Team and expert advice from its Technical Advisory Centre.

“We firmly believe the HVAC industry deserves a complete service offering and we’re in a unique position to provide it,” said Debra Green, Knauf Insulation’s HVAC Market Manager. “As the only manufacturer of both glass and rock mineral wool insulation products, we offer designers impartial advice and the opportunity to benefit from their different qualities and characteristics. Our continual investment in product development and customer support speaks volumes for our commitment to the industry – we’ve got it all wrapped up!“

Glass and rock mineral wool have excellent thermal, acoustic and fire-insulation properties. Of the two, glass mineral wool is accepted as the material-of-choice for HVAC insulation generally, whereas rock mineral wool is preferred for applications involving tougher operating conditions. Rock mineral wool is available in higher densities than glass and can therefore offer higher compressive strength – it’s ideal for over cladding ductwork, for example – and has better fire resistance properties when these are needed.

Both glass and rock mineral wool products offer definite benefits over phenolic foam products and the arguments for their use are compelling. Neither react with copper or steel in the same way that phenolic products can if the protective coating applied to the bore is either damaged or breaks down. Jointing and detailing operations are easier and more thermally effective as the wool ‘knits’ together or can be ‘scrunched-up’. Mineral wool insulation is also more durable and better able to withstand damage and, with no loss of thermal performance caused by the gradual loss of the phenolic foam’s gas, has a greater life expectancy.

The investment at Knauf Insulation’s Queensferry plant in North Wales was a major one. Apart from increasing capacity to 33,000 tonnes per year, all parts of the production line were either replaced or upgraded. New, state-of-the-art fiberisation equipment has lead to very high quality fibres being produced and this has resulted in a material that is more consistent in both density and performance. To mark the changes, Knauf Insulation has rebranded the range from Rocksil®, to Rocksilk®, Rock Mineral Wool. What a difference a ‘k’ makes!
