The current design of some wood-framed, non-ventilated roof assemblies in northern climates results in discontinuities in the vapor/air barriers, which allows moisture-laden air to migrate into the truss space and condense.
Wood flooring offers more advantages than just aesthetic appeal in both homes and commercial settings. It is easy to clean and is significantly more stain-resistant than carpeting. Wood is also strong and durable, and if properly cared for, its hard surface can last for decades.
Robotics developer Innovation First International in Greenville, Texas, has utilized metal panels for its building envelope system to add an all-metal aesthetic, provide insulation, and create modularity.
Inspired by building science, insights from commercial construction in Europe, and feedback from architects, cellular glass is being re-introduced as an approach for insulating mission critical enclosures, specifically in commercial rooftop applications.
As manufacturers introduce materials with new properties and attempt to push the boundaries of building envelope construction, it is crucial the industry agrees on terminology for communicating the specific functions and purpose of these materials to avoid confusion and costly errors. In this regard, the term ‘air/vapor barrier’ is misleading and should be replaced with more appropriate terminology.
