Continuous insulation (CI) is described in ASHRAE 90.1 as “insulation that is continuous across all structural members without thermal bridges other than fasteners and service openings. It is installed on the interior, exterior, or is integral to any opaque surface of the building envelope.”

If you are confused by that description, you are not alone. I recently came across a comment on an online message board in which the person stated, “The only thing I know about continuous CI is that it’s required by ASHRAE 90.1.”

If you are looking for more information on CI, RC’s sister publication, Architectural Roofing & Waterproofing, has a webinar on the subject scheduled for April 16. It’s titled “Continuous Insulation and Beyond,” and it will define continuous insulation and explain how its use affects energy code compliance.
