In this video, Jason Wigboldy shares some innovative fastening solutions to attach mineral wool continuous insulation when using the Knight Wall MFI® Rain Screen Attachment System. As you can see, we are demonstrating a vertical installation of the Knight MFI System S-Series with 2" thick mineral wool insulation. The Therma-Bracket-S thermally isolates the cladding from the steel stud structure greatly increasing the effective R-value of the continuous insulation. These brackets are installed over the air and weather barrier at a specified spacing and pattern determined by the cladding designer. The vertical S-Rails are then attached to the ThermaBrackets which creates an ideal cladding attachment substrate. Prior to the cladding attachment mineral wool insulation panels are fitted between the rails. The S-shaped design of the Therma-Bracket-S enables the mineral wool insulation to be inserted behind the rail on one side of the S-Rail bay. The insulation is pressure-fitted into the other side of the bay, and can be permanently secured using simple solutions from Rodenhouse Inc. It is important to secure the insulation panels against the structure to maximize insulation efficiency and also to prevent sagging or shifting of the insulation over the lifespan of the building. Simple insulation attachment solutions from Rodenhouse Inc. include the Thermal-Grip® ci prong washers with Grip-Deck® ci ceramic coated self-drilling screws. Another option is the Thermal-Grip® Impaling Pin Fastener which is mechanically attached to the steel stud while the washer helps seal the air and weather battier penetration. A third option that does not penetrate the air barrier is the Grip-Plate® Corrugated Strap that is attached to the Vertical S-Rail. After the Insulation is inserted the strap is bent and rotated into place to permanently secure the insulation against the air and weather barrier. For horizontal S-Rail applications, or for when the ThermaBrackets are taller than the thickness of the insulation like you see here, we recommend permanent attachment of the mineral wool with our 3" dia. Grip-Lok® Hurricane washer and Grip-Deck® ci ceramic coated screws. The large diameter washer prevents crushing of the insulation and can span the joints between insulation panels to help minimize fastener penetrations and thermal-bridging.
