This 7-hour, 7 CPD credit course is an in-depth examination of the extensive insulation testing undertaken at our Centre of Excellence in Port Coquitlam. There are many choices for builders to consider as they explore their options for advanced energy performance in basements, walls and roofs necessary for conformance with the targets set by the Step Code for Part 9 homes and buildings. Builders must avoid unintended consequences that can arise from the reduction in energy flow through the building enclosure and the resultant reduction in drying potential that has always helped to protect structures with lower energy performance. It is also important to note that some changes in the manufacturing of some insulation materials in response to environmental impact has apparently altered the performance of some old, familiar materials.

This focused presentation will provide valuable insight into the true performance of fibrous insulations, rigid foam and mineral fiber products, and polyurethane spray foam insulation in various densities. Results of testing will be presented using graphs, photo’s, video, and 3D CGI graphics modelling to ensure clear explanations of the findings and easy-to-understand conclusions will be taken away by all attendees. Much effort has gone into simplifying the conversation so that attendees will leave informed and not confused.
The testing of fibrous insulation (batt and blown fiberglass, mineral fibre and cellulous) included guarded hot box testing and internal thermal scanning to identify anomalies with various fibrous insulation assemblies. The purpose was to predict real insulation performance at increased depths and to establish if convective short-circuiting within the insulation would develop and how this might be controlled.
The testing of rigid foam used extreme conditions to establish greater understanding of dimensional stability, thermal bridging at joints, true thermal performance across service temperatures, and saturation under prolonged wetting. The testing of Spray Polyurethane foam insulation sheds new light on adhesion concerns, environmental influences during application and the effects of mechanical alteration (scarfing, racking and load deflection of the structure).
The presentation will offer insights, highlight concerns, and identify new testing recommendations arising from this body of work. This seminar is for anyone looking to truly understand insulation performance.
