Learn about various types of strapping and bracing.

1. STRAPPING

2. CORNER & ANGLE STRAPPING
PRE-FORMED CORNERS
• Wrap around corner and overlap
two webs on adjacent straight block
• Use at least 2x4 dimensional
lumber
JOBSITE ASSEMBLED ANGLES
• Use full height OSB or plywood
wide enough to cover two webs
each side of angle
• Attach 2x lumber height of wall in
corner on both sides

3. WINDOW & DOOR STRAPPING
WINDOW & DOOR OPENINGS
• For metal or vinyl, follow manufacturer’s
recommendations
• For external wood, picture frame wrap both sides
• For internal wood, attach to EPS with long screws &
plastic washers
• Brace wood bucks vertically & horizontally every 18” with
2x4 or wider
ARCHED OPENINGS
• Brace horizontally at bottom of arch, vertically in center,
and two pieces horizontally
• Brace bottom of window like standard opening but
without corner bracing
SILL OPENING
• Less than 4’ – drill one 5” or larger hole in center
• More than 4’ – drill one 5” or larger hole every two feet

4. T-WALL & PILASTER STRAPPING
• Strap both the same
• Use 2x6 or larger
lumber to cover two
webs each side
• Additional support
needed for pilaster end
cap

5. NON STANDARD JOINT STRAPPING
Any vertical joints that are
too close together or not
offset properly

6. RADIUS WALL STRAPPING
• Fasten 1/8” hardboard strips to
inside and outside radius flush to
bottom of each course
• Pieces must be tight and aligned at
top prior to fastening
• Install bracing on the radius

7. STANDARD BRACING
• Provides access to upper
courses
• Keeps wall aligned prior to and
during the pour
• Typically installed on inside of
wall structure
• Spacing depend on height &
core size of wall
• Consider safety regulations,
code compliance, and
engineering requirements when
choosing bracing system

8. TALL WALL BRACING
• Tall walls are common
construction features
• Numerous scaffolding
companies
manufacture tall wall
bracing for the ICF
industry
•Considerations:
•Safety regulations
•Code compliance
•Engineering
requirements
