Ductwork
other benefits, while saving the building owner significant sums in running costs. Mineral wool, in particular, offers a broad spec- trum of benefits across HVAC solutions and in terms of acoustic performance scores exceptionally well. Complaints about noisy systems can be dramatically reduced, by insulating pipes and ductwork to reduce the sound of ventilation and air movement – and all mineral wool products whether labelled ‘acoustic’ or otherwise, deliver excellent acoustic performance. Extending occupancy well-being to that of safety,
mineral wool also offers outstanding fire perform- ance; solutions are predominantly non-combustible (Euroclass A1), with foil faced pipe sections typi- cally achieving Euroclass A2 (or limited com- bustibility). These characteristics lend themselves to maximum service temperatures of up to 250°C. From an installation perspective it’s worth
remembering that mineral wool is flexible too. Ductwork comes in many shapes, sizes and
profiles - and maintaining intimate contact to, and optimising performance of, ductwork is achievable without the necessity to groove or profile the insulant, potentially to the detriment of its in situ performance. When you consider the multitude of influences
on occupancy productivity and well-being – whether that be thermal comfort, reducing noise pollution or the contribution a product might make to fire safety and sustainability – it soon becomes apparent the value good quality HVAC insulation products can add to a building’s performance. For installers looking for the most rounded so-
lution, mineral wool delivers on all counts. • James Hulbert is the product manager for Knauf Insulation
16% of employees are affected by noisy HVAC systems and research shows that exposure to noise such as this reduces accuracy of work by 67%
Knauf’s range of glass and rock mineral wool insulation differentiates itself from other mineral wool manufacturers’ as it features a no-added formaldehyde ECOSE Technology binder (the ‘glue’ that binds the fibres together) throughout
