Skylight and Tubular Daylight Devices Including Details for Installation

Why take this session? Our team constantly seeks out information and testing from around the world. We work closely with some of the biggest research projects in Building Science and our reputation as the Guardians of Part 9 is growing throughout North America. This Seminar series focuses on Roofs, Decks, Balconies, Walkways, Vertical Penetrations, Skylights and Tubular Daylight Devices. The sessions begin with a review of conditioned and unconditioned attic spaces and the Building Science that describes performance expectations and changes as energy efficiency targets for homes evolve. Framing considerations to accommodate final architectural form including tips and tricks to improve roof/deck performance that still deliver level thresholds, ornate roof features, and other preferred details. Solar photovoltaic installations and future proofing for upgrades to solar systems will be explored. Durable penetration details for mechanical, drainage, chimneys, skylights (pressure plate and dome glass), and tubular daylight devices will be covered and a wide cross section of roofing materials will be reviewed (metal, tile, wood, traditional shingle, and others). Performance concerns such as unvented voids, membrane shrinkage, and differential framing settlement will be explained. Insulation options for attics including the use of spray polyurethane foam insulation, inverted roof membrane assemblies, flash-and-fill, and more traditional approaches will be presented. Phenomena such as night sky cooling, ice damming, and attic condensation will be described, and other factors affecting performance will be discussed (effective ventilation requirement, controlling mechanical discharge locations and re-configuring home design to take advantage of conditioned attic spaces for alternate purposes such as mechanical system installation and even storage. Single ply membranes including balcony vinyl, EPDM, and liquid applies will be reviewed and challenges and opportunities with all roofing materials and approaches will be discussed. Even a brief conversation will be had relating to exotic roofing choices ranging from copper and zinc, to slate, and even thatched roofs. This series is devoted to increasing awareness about a wide cross-section of material, system and assembly solutions and advantages and challenges for each. What’s on top in residential construction will necessarily change as we enter an era of significantly improved energy performance, and this series will prepare the industry for this transition.
