Insulation & R-values

One the feature of this renovation, is that the existing house & the additions are very well insulated and air tight. To achieve this, we removed the existing wall & ceiling batt insulation and used spray-foam insulation in between the roof rafters, blow-in spider insulation in the exterior walls and spray- foam insulation on the exterior crawl space walls. The R-values meet the new International Energy Conversation Codes requirements. The blower door test (to verify how air-tight the house is) will be performed at the end of this week, and we will share the results with you.
