B - Quad-Lock Building Systems

PRODUCT MANUAL
Check the sill for level and adjust. Now continue on with building the wall around the window bucks. Run panels just past
the inside of the bucks. Place split ties as close to the buck as possible.
Fasten around both sides of the perimeter of the buck, using Wind-Locks and screws at maximum 6" [152mm] centers.
Trim away excess foam with a hand saw. Make sure that you have access to the wall cavity through the sill, to ensure
concrete consolidation. Reduce waste by saving all your leftover pieces that are 12" [305mm] long or more, and using
them on the second to last row at the top of the wall where there is less form pressure.
When window and door openings occur in locations close to corners, the corners may tend to act more like columns and
require additional tie-backs. When an opening is less than 4 feet [1.2m] from a corner, span a 2x from the corner across
the opening and well into the wall beyond at about 3 ft. [90cm] O.C. vertically. Screw through the 2x into the tie flanges
to anchor the corner back to the rest of the wall on the other side of the opening.
Attaching Storm or Typhoon Shutters
Many hurricane-prone coastal or island communities are now requiring storm or
typhoon shutters on the exterior openings of buildings. In this case, it is wise to
have a concrete surface to mount the shutter directly to, rather than reaching
through the EPS panels with long fasteners into the concrete. Long fasteners that
penetrate the foam are subject to a “cantilever” condition that will put large
amounts of shear stress on them, and are therefore not advisable.
A form must be constructed that is a hybrid of the Internal Wood Buck described
above, and an External Wood Buck made from plywood. This hybrid form will
allow the concrete to flow to the outside of the building in a band along the header
and sill of the window or door, to which storm shutters can be properly attached.
External plywood form components should be made large enough to be screwed
to tie flanges above and below the opening. See diagram for suggestions on
construction of a hybrid form.

IMPORTANT: When window and door openings occur in locations close to corners, the corners may tend to act more
like columns and require additional tie-backs. When an opening is less than 4 ft [120cm] from a corner, span a 2x from
the corner across the opening and well into the wall beyond at about 3 ft. [91cm] o.c. vertically. Screw through the 2x
into the tie flanges to anchor the corner back to the rest of the wall on the other side of the opening.
