B - Quad-Lock Building Systems

PRODUCT MANUAL
WINDOW INSTALLATION:
Windows can be attached to rough openings in Quad-Lock walls in one of several ways:
1. Screw window flanges to stops that are fastened to internal buck-outs. This method will have required oversizing
the rough openings by 2 times the stop material thickness. (Example 1½" + 1½"= 3" [38mm + 38mm = 76mm]) It is
advisable to add a small amount of extra room to insure a fit.
2. Screw windows to “L” metal that has been fastened to bare concrete, left exposed after removal of temporary rough
opening forms. Flangeless windows are generally fastened through the window frame and directly into concrete.
3. Use adhesive and 3¼" [83mm] min. length screws to fasten window flanges to surface of foam, and into internal
buck-out material behind foam panels.
4. Flangeless windows are generally fastened through the window frame and directly into concrete, left exposed after
removal of temporary rough opening forms.
Window Flashing:
When installing windows, Quad-Lock recommends that proper precautions are made to resist the intrusion of water
through the window opening. In addition to adherence to the window manufacturer’s recommendations, Quad-Lock
makes the following recommendations:
• Window rough openings should be flashed with a durable waterproof flashing material which is rated for contact
with Expanded Polystyrene
• Layers of flashing should be “shingled” from the bottom of the window opening to allow moisture to shed away from
the opening. Flash the sill area first, then install the window with caulking, then the side flashing, and lastly the
head flashing.
• “Peel-and-stick” flashing products should only be installed after a compatible primer is applied to the EPS to
promote adhesion and durability.
• If EIFS or cement-based stucco is to be applied as a finish layer, the surface of the flashing material should be
textured to promote adhesion between the flashing and the cladding product. (Suggest: Polyguard “Tile-Guard”

Consult the window manufacturer’s installation instructions in all cases and call the Quad-Lock Technical Department
with questions.
FLOOR CONNECTIONS
Quad-Lock can accommodate several wall-to-floor connection details, depending on the type of floor system called for by
the building designer, including conventional lumber, engineered wood joist, metal joist, heavy timber, suspended
concrete slab, and concrete T-beam slab construction.
Ledger Connections for Wood Floors
Ledgers may be attached using most generally accepted building practices. Commonly, ledger boards are either pre-set
with bolts or attached using one of several ICF Ledger Connector systems.
ICF Ledger Connectors (ICFLC)
Quad-Lock distributes the ICF Ledger Connector System from Simpson Strong Tie Co. The system provides easy, quick
and versatile installation of ledgers for use with regular thickness Quad-Lock Panels. Ledger brackets can also be used
for the attachment of interior walls, overhead door attachment etc.
Quad-Lock recommends that the ICFLC, ICFLC-W, ICFLC-CW and their associated fasteners should NOT be used in
contact with treated lumber, in exterior applications, or anywhere water is likely to be present (unless you ensure
compatibility of your treated lumber with the metal components).
