DESCRIPTION OF THE PRESENTATIONS

Insulation: What Is It and how Does It Work? Heat Air and Moisture Flow As Applied To Roofing.
Dr. Straube will review the basics of heat transfer, types of insulation and how they function will be reviewed. Factors affecting the performance of insulation such as aging, dusting and moisture content will be discussed. Recent industry breakthroughs such as phase change materials and void insulation panels will be discussed.
Dr. John F. Straube, Ph.D., P.Eng. holds a joint appointment as an associate professor in both the department of Civil Engineering and the School of Architecture at the University of Waterloo, where he teaches courses in structural design, material science and building science to both disciplines. He has been deeply involved in the area of building enclosure design, moisture physics and whole building performance as a consultant, researcher and educator. His research and practice have focused on the design of energy efficient, healthy and durable buildings and the development of new building systems and products. His work is supported by advanced computer simulation and full scale natural-exposure performance monitoring.

CSA123.21 dynamic wind uplift standards versus FM.
The CSA standard will become part of the 2015 NBC. Currently the CSA standard only relates to mechanically fastened membrane assemblies and includes such manufacturers as Soprema, Firestone, Carlisle, and others. Very soon, within the next few months, this standard will expand to include adhesive applied assemblies and that is exciting in our roofing industry. More and more project designers are looking to adhesive applied assemblies for various reasons and these new established CSA standards will address these adhesive issues - something that to date FM has refused to look at.
Josh Jensen, AScT, CHI, RRO, RRC is the manager of roofing services at JRS Engineering Ltd. He holds a diploma from BCIT in Architectural and Building Envelope Technology. Josh is a member of the technical roofing committee of the RCABC and has been very active in the executive of BCBEC and the Western Canadian Chapter of RCI.

What I wish Roofers knew:
Mons Aase, RRO is the Owner and operator of Aase Roof Inspection Ltd., a firm that performs roof inspection and condition surveys in Prince George and in a large portion of the North and interior of British Columbia. Mons is a member of RCABC’s technical committee and vice president of RICABC. Throughout his 25 years of reviewing roofs Mons has amassed a large collection of roofing bloopers which he proposes to share with us in this lighthearted presentation. Mons will use his considerable experience reviewing roofs in Northern BC and discuss recurring problems and how they can be avoided.

More on Attics and Moisture:
Moisture in attics seems to me a more common problem in the Lower Mainland of British Columbia than ever before. Dr. Straube will draw on the knowledge he has gained from his own work in this region to offer his thoughts on why this is so, and on attic design or remediation for this climate. This presentation will discuss role of the soffit venting in reducing (or increasing?) moisture loads, and the possible contribution of night sky radiation in attic wetting.

What I wish Consultants knew:
Laurence Matzek has been roofing since 1985. As president of the Roofing Contractor’s Association of British Columbia and President of Bollman Roofing & Sheet Metal Ltd. Mr. Mattzek is well placed to discuss the divide that sometimes exist between practice and theory. Mr. Matzek will draw from his considerable experience to help the inspection industry realise where improvements can be made in their practice.

A Look to the Future:
Dr. Straube’s practice is worldwide. His travels has offered him unsurpassed opportunity to view innovations and stupendous failures. In this final presentation, Dr. Strube is unleashed to discuss applications of pitched roofs, low slope roofs, condensation, drying, solar heating, white roofs green roofs, when to vent, when not to, when you can choose, can you use spray foam.
