WHY CONTINUOUS INSULATION? Meeting Demanding Standards and Changing Codes What Is Continuous Insulation (CI)? ASHRAE 90.1 defines continuous insulation as:1 “...insulation that is continuous across all structural members without thermal bridges other than fasteners and service openings. It is installed on the interior or exterior, or is integral to any opaque surface of the building.” ASHRAE Standard 90.
ENERGY EFFICIENCY Contributing to Sustainable Buildings The Evolution of Energy Efficiency We have come a long way with the development of energy-efficient buildings. 1900s No Insulation 1940s–1970s Limited Insulation In the 1900s, an exterior wall would look pretty much like this: no insulation. As we move into the 1940s and especially during the energy crisis of the 70s, designers and building owners start to recognize the need for more insulation, but it’s still used in a limited amount.
3. Envelope tradeoff • Tightly defined • Allows for tradeoff between various parts of the building envelope • ASHRAE Standard 90.1-2007/2010 provides the basic rules • Tradeoff is implemented in the COMcheck™ software Going Beyond Codes Many owners, designers, and contractors feel that the insulation requirements set out in state-adopted codes are not robust enough to truly save energy and reduce greenhouse gas emissions.
INTRODUCTION TO OWENS CORNING® THERMAFIBER® RAINBARRIER® CONTINUOUS INSULATION Comfort, Safety, and Sustainability Thermafiber RainBarrier continuous insulation (CI) is designed to work with a diverse range of cavity wall or open-joint façade systems.

Impasse Hangers ® Impasse Hangers provide a precise, faster, and safer installation of RainBarrier insulation without the need to penetrate the Air and Water Barrier (AWB). Impasse Hangers facilitate a logical order of installation and installation efficiency, and allow for positive mechanical attachment directly to the channels.
Clip and Rail Systems Thermafiber, Inc. is a leader in continuous insulation design by providing installation compatibility with a wide range of RainBarrier hanging options designed to work with virtually any cladding system in the industry, and accommodate both imaginative designs and demanding specifications. ® Glass Fiber Reinforced Clips These thermally isolated clips reduce thermal bridging between the cladding and the wall, improving the effective R-value of the insulation.
Glass Fiber Reinforced Clips This insulated composite clip and rail system is composed of bioresin and recycled fiberglass.
Reinforcement and Attachment Methods Wire Ties or Flat Anchors RainBarrier HD and RainBarrier 45 insulation can either be impaled onto shelf-type wall ties or installed so wall ties occur at insulation seams. When fit between wall ties, the insulation is secured to the wall tie with Thermafiber RainBarrier clips.
Barrel-Style Anchors Brick Veneer Anchor Wall When installing masonry veneers, Owens Corning RainBarrier 45 and RainBarrier HD continuous insulation can be attached using the single-barrel masonry anchors with 2-inch or greater washers. Secure by screwing the appropriate type of anchor (for wood, steel, or concrete/masonry) through the insulation as recommended by the anchor manufacturer.
Direct Attachment Method By utilizing the high compressive strength of rigid mineral wool continuous insulation board, only long screws penetrate the continuous insulation to secure the cladding attachment system (such as girts or channels) to the stud framing below the CI. This reduces the thermal bridging through the assembly. Typically, cladding is attached to 16-, 18-, or 20-gauge channels, girts, or dimensional wood furring.
