Vision Reborn: Modern FRP composites restore ornamental masonry

1

Sometimes, the best way to restore an historic building is not the way it was originally built. The methods and materials of construction have changed, and newer options are available to re-create the original design. Labor-intensive approaches of a century ago are now prohibitively expensive. This
 is especially true in the case of decorative details, which were sometimes hand-made.

Sound-deadening with Sprayfoam: Adding unexpected value with SPF

dreamstime_l_18543982

Insulating walls with low-pressure sprayed polyurethane foam (SPF) is a common practice among builders and architects for various reasons—such as increased energy efficiency, structural support, and overall comfort. One of the ways SPF can increase the comfort of a structure is through the material’s sound-deadening properties, which contractors can employ to bring additional value to a project.

Continuous insulation (ci) has been a component of exterior wall assemblies for almost a half-century in North America. By minimizing energy loss caused by thermal bridging and the risk of condensation caused by water vapor diffusion, exterior ci can improve building durability and benefit the environment. However, using rigid foam plastic comes with certain design considerations that must be reviewed early in the design process.

Curtain walls are often the focal point of aesthetic design for a multi-story building. Behind the attractive façade are the pedestrian, yet arguably more important, functional components that ensure safety and reliability—fasteners that transfer loads both imposed and experienced by the assembly to the building’s structural framework.
