This programme looks at the various ways of subduing noise in buildings.
It explains the scientific foundations of sound, addressing loudness, frequency, amplitude, pitch and reverberation. The effect of distance upon loudness is examined and the workings of logarithms explained, allowing the decibel (a logarithmic unit) to be understood. The different types of sound transmission (impact noise, flanking and airborne transmission) are addressed, and appropriate responses to minimise noise discussed. The difference between sound absorption and sound insulation is highlighted, and some of the conflicting consequences of sound minimization are outlined.
Visqueen launches Ultimate Self Adhesive Membrane for hydrocarbon and VOC-contaminated sites
The construction industry faces growing challenges when building on increasingly complex brownfield sites. Alongside the need for effective waterproofing, developers and contractors must now address a wider range of ground contaminants, including hydrocarbons, volatile organic compounds (VOCs), and hazardous ground gases, while maintaining programme efficiency and installation quality. Against this backdrop, Visqueen has expanded its gas protection and waterproofing portfolio with the launch of Visqueen Ultimate Self Adhesive Membrane, a new hydrocarbon and VOC-resistant self-adhesive tanking membrane. Developed as the latest addition to the Visqueen non-foil gas barrier range, the new membrane combines proven gas barrier and waterproofing performance to help specifiers address multiple site challenges with a single solution.

Siderise: Helping to bridge the gap between Gateway 2 approval and on-site fire protection
While the new building safety regime hasn’t fundamentally changed what requirements higher-risk buildings (HRBs) must meet to comply with the Building Regulations, it has significantly increased the breadth, depth and volume of evidence that must be supplied to demonstrate this. As a result, project teams have had to adapt the way they work and even look beyond their roles to understand how their actions may impact the next Dutyholder in the chain. For specifiers, this can include considering what supporting services are offered with life safety-critical elements to enable correct design, installation and maintenance. Early engagement with manufacturer technical specialists can help identify any practical challenges that may arise onsite. Then, during construction, these services can help support the translation of design intent into reality so that buildings are safe for occupation.

RIBA CPD for Architects: Understanding Flooring Specification and Detailing
For architects and specifiers, flooring details can have a significant impact on the safety, accessibility, durability and overall performance of a building. Yet the technical considerations surrounding stairways, floor transitions, and floor finishes are not always straightforward.
