Innovations reduce air leakage for energy efficient rolling steel door

Print

Until recently, air leakage was not a consideration in the rolling steel door industry. It was thought to be an impossible task—how do you stop air from coming through a door that is slatted? However, as codes became more stringent regarding reductions in air leakage, it started limiting the ability for architects to specify the best closure product for their application.

When properly applied, tests can yield valuable insight into the installed performance of systems, aid investigators in determining the cause of a failure, or help to determine if a product is performing to its intended level. However, when improperly applied, many tests and standards can produce misleading results, improper conclusions, and lead to unnecessary repairs or remediation efforts. Within this context, the article takes an in-depth look at roofing assemblies, along with glazing, masonry, and air barrier assemblies.

Discussing specification writing and documentation details can be challenging, but the right set of specifications is a key component in the process to deliver a successful project. It is crucial the specification writer understands the intent of how systems will operate and how systems relate to each other. This is getting even more important as new buildings are getting more complex and have loftier energy efficiency goals. This article describes the most important aspects of construction specifications to ensure a good outcome for energy efficient buildings.
