ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) standard 90.1 defines continuous insulation ("ci") 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."
While "ci" is not a new concept, design and construction professionals and even building owners are becoming increasingly aware of the value of "ci" in helping to achieve desired thermal and moisture performance.
