What is the effective thermal resistance of foil-faced bubble insulation and other similar products recognized by NRCan to model homes?
At this time, despite claims made by Canadian manufacturers and salespeople, and unless otherwise proven by a respected third-party testing agency against a recognized standard for the testing of such reflective materials, NRCan recommends the following effective thermal resistance maximum values for foil-faced bubble insulation products or the foil-faced portion of a laminated layer of foam or fibre-based insulation board when modeling them in the simulation software. • RSI 0.26 (R 1.5) where the bubble layer is between two layers of foil without air spaces in front of the foil. • RSI 0.53 (R 3) where the bubble layer is between two layers of foil with only one air space in front of the interior facing foil. • RSI 0.62 (R 3.5) where the bubble layer is between two layers of foil with air spaces in front of the foils. • RSI 0.62 (R 3.5) where the foil layer is between two clear layers of bubbles acting as air spaces NRCan does not comment on other characteristics of foil-faced bubble i
