NRCA has announced the release of NRCA Guidelines for Condensations and Air Leakage Control, which provides comprehensive information about the fundamentals of condensation and air leakage and vapor and air retarders for low- and steep-slope roof systems.
Intended to provide in-depth, best industry practices and technical information concerning the design, materials and installation of quality roof systems, NRCA Guidelines for Condensation and Air Leakage Control contains all information regarding condensation and air leakage control from The NRCA Roofing Manual: Architectural Metal Flashing, Condensation and Air Leakage Control, and Reroofing – 2014.
“Building code requirements are forcing roofing contractors to become more familiar with condensation and air leakage issues,” says Joan Crowe, an NRCA director of technical services. “The guidelines in this manual are a great tool in assisting with this issue.”
This manual is best used with other current editions of The NRCA Roofing Manual, including The NRCA Roofing Manual: Membrane Roof Systems – 2011, The NRCA Roofing Manual: Metal Panel and SPF Roof Systems – 2012 and The NRCA Roofing Manual: Steep-slope Roof Systems – 2013.
NRCA Guidelines for Condensation and Air Leakage is divided into four chapters:
Chapter 1 – Fundamentals of Condensation and Air Leakage Control contains information about moisture sources, principles of vapor movement and climate conditions.
Chapter 2 – Condensation Control for Low-slope Roof Systems contains information about preventing condensation accumulation and vapor retarder design for low-slope roof systems.
Chapter 3 – Condensation Control and Ventilation for Steep-slope Roof Assemblies contains information about preventing condensation accumulation, attic ventilation and unvented attics.
Chapter 4 – Air Retarders for Roof Assemblies contains information about air leakage, standards and codes language and air retarder design.
