Unvented Roof Systems and Innovative Advanced Framing Strategies
This webinar, held on February 12, 2015, focused on methods to design and build roof and wall systems for high performance homes that optimize energy and moisture performance. Presenters and specific topics for this webinar included:
- Joe Lstiburek, Building Science Corporation, presenting Advances in Unvented Roof Technology. It has become clear that unvented roofs must be conditioned in most climates or some other means of moisture removal is necessary for the attic space. This presentation will discuss several of these approaches, including the use of diffusion venting and dehumidification. These approaches will allow the use of cellulose and fiberglass insulation systems rather than the current approaches that rely on rigid insulation or spray polyurethane foams. View his presentation.
- Vladimir Kochkin, Home Innovation Research Labs, presenting Construction Guide: Energy Efficient, Durable Walls. Strategies to design and build high performance walls can vary significantly by climate zone, and this discussion will focus on approaches for climate zones 3-5 that increase energy performance and reduce moisture issues in walls. The presentation is based on the Builder’s Guide to High Performance Walls, which will be published in 2015. View his presentation.
