Design assist: Reshaping the project experience

Architects are not experts in building materials, and sometimes they may specify a product for a particular project element without realizing it may not be the right fit for their design needs. Through the design-assist process, a manufacturer could fill this knowledge gap by providing the project team with...

Integrating fenestration with the wall

Selection of fenestration systems for specific wall assemblies is a process in which performance characteristics, such as structural capacity, the resistance to air infiltration, and water penetration, and thermal attributes are evaluated along with aesthetics and cost. However, the integration of the system(s) under consideration with the adjacent exterior...

The air/vapor barrier must die

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...

Writing a spec from scratch

Most technical specification template sections are available through software programs, but what if a template does not exist for a particular product or assembly? The following article outlines some of the steps to take when creating a spec from scratch.

What did we get, anyway?

Selection of fenestration assemblies (utilizing both window and storefront systems) can be challenging due to the number of ancillary components/accessories available—materials with different performance characteristics compared to the main fenestration element.
