Résumé
This paper compares the physical and economic (life cycle) performance of insulation materials placed on the exterior, above and below-grade portions of residential basements, in lieu of non-insulating drainage membranes and drainage layers, combined with internal insulation. The findings are premised on research, field studies and analysis associated with the Performance Guidelines for Basement Systems and Materials Project undertaken by the Institute for Research and Construction, National Research Council Canada.The thermal and drainage performance of several insulation materials installed on the exterior, basement portions of a test house located on the NRCC campus in Ottawa were monitored for a period spanning two heating seasons. In addition to assessing the effective, in-situ thermal resistance of the insulation materials over the study period, the results for drainage effectiveness were also compared with conventional drainage layer and membrane materials commonly used in residential basement construction. An economic analysis of the exterior basement insulation system (EIBS) applications was also performed to compare their cost effectiveness with interior insulation applications relying on drainage membranes for exterior moisture protection. A comparison of critical considerations pertaining to exterior and interior basement insulation strategies is also presented, along with relevant conclusions based on the testing, energy modelling and economic assessment of EIBS.
