Attaching Your Wall Panel to a Concrete Wall or Slab
Attaching RAY-CORE Wall Panels to a Concrete Wall or Slab is handled basically in the same manner as attaching any wall to a slab or concrete wall. Frame your walls as instructed previously per engineer or architect and code requirements. In preparation, mark on panel the locations of all foundation bolts. Make a 4”x4” OSB template and attach to the foam with nails. Take a drywall saw and carefully cut the foam away from the bottom plate at the anchor bolt locations. Number and reserve the foam blocks as they will be reinserted, filling the voids once the bolts are secured to the bottom plate. Predrill bottom plate for bolts.
Apply a foam sealant per code between the bottom plate and concrete to provide an airtight seal. Stand wall over bolts. Attach with washers and nuts per code. Reinsert foam blocks in panel voids and seal in place with construction adhesive as previously instructed.
Best Practices: After installation of wall, inspect attachment to concrete for any open joints, cracks or voids, and to avoid air infiltration, seal bottom plate with flexible caulk on both sides of wall.
Hurricane Strapping Installation
Attaching RAYCORE Wall Panels to Hurricane Strapping on a Slab is handled basically in the same manner as attaching hurricane strapping to any wall. Frame your walls as instructed previously per engineer or architect and code requirements. Take a drywall saw and carefully cut the foam away from the bottom plate in the shape of the strap sufficient to allow installation and attachment to the wall framing. Remove only the amount of foam necessary to perform the installation. Upon completion of the installation, fill the voids and seal with a foam friendly construction adhesive.
Hurricane Straps example (ie. Simpson STHD straps). As you would with conventional stick framing, hurricane straps are nailed into the RAY-CORE Wall Panel’s integrated studs. If the integrated stud in the panel does not line up with the STHD strap then you will need to place a stud in proper location during the framing process.
