Timber has long been a staple construction material for domestic scale properties, although it is increasingly being used in high-profile structures such as the Weald & Downland Gridshell. However, exposure to the elements can result in changes to the chemical and physical properties of wood, affecting its aesthetics, structure and longevity.
This programme takes a look at different forms of weathering – from UV radiation and wind, through to rainfall, ice and snow – and their impact upon different forms of wood. It discusses the bleaching effect of sunlight in relation to softwoods and hardwoods, dark timbers and light timbers, and with reference to individual species of tree. The effect of wood moisture content on weathering is explained, while the relative merits of paints, varnishes and wood stains as preservatives are examined. It also looks at the aesthetic pros and cons of timber weathering.
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.
