launches guide to BS 5422:2023
o support HVAC and building services professionals in meeting the latest thermal performance guidance, stone wool insulation manufacturer ROCKWOOL has released its Guide to BS 5422:2023. The new brochure clarifies recent changes to BS 5422, the technical guidance document covering thermal insulation of building services, and is available to download. BS 5422:2023 presents updated specification recommendations for effective thermal insulation of pipework, ductwork and other building services equipment, covering a range of applications throughout commercial and domestic buildings. Changes to the guidance includes the removal of thermal performance for legacy materials, adjustments to the heating tables, and the change from ‘National Class’ reaction to fire to ‘Euroclass’ classifications.
The changes presented in BS 5422:2023, effective since 30 June 2023, give designers more stringent thermal performance targets in line with energy efficiency commitments and the route to net zero. The ROCKWOOL Guide to BS5422:2023 puts these changes

SuperPhon panels provide reverberation control at new school
C
MS Danskin Acoustics’ SuperPhon panels are contributing to reverberation control at a newly built school in East Hertfordshire, helping to ensure standards for acoustics in new school buildings are met.
Buntingford First School is a school for around 330 children between the ages of three and nine, which opened for the 2023 autumn term. Built to Passivhaus standards by Morgan Sindall Construction for Hertfordshire County Council, the 1,643 sqm school includes a nursery and ten classrooms. During construction

New school buildings must satisfy the requirements of Section 1 of Building Bulletin 93 (BB93) – setting out the constructional standard for acoustics in new school buildings.
SuperPhon is available in standard sizes, thicknesses and finishes, including wipe clean and art panels, but also as bespoke panels in terms of size, thickness, shape or fabric facing. Designed for use in applications, including recording/rehearsal studios,
