  1. Determine if your home’s underlying material (Figure A) is:
    • Wood
    • Concrete
    • Hollow block
    • This will help determine the placement of the fasteners to attach the panels to.

  2. Determine if your windows and door casings are:

    • Recessed with an extended sill or without a sill
    • Flush to the wall or protrude past the wall

    • Check if shutters, down spouts or other items might interfere with fastener placement.

      Take note of your exterior siding. The thickness of your walls and where you plan to attach fasteners will determine the length and type of fastener required.

  3. Fasteners MUST penetrate (Figure B) the exterior finish into a solid substrate to provide a proper anchor. This is crucial to ensure a properly installed panel.

  4. Count the number of openings (Figure C) to which you wish to attach panels. Include:

    • all windows and doors with glass
    • roof and gable-end vents
    • any other openings that would allow wind to enter your home if damaged
    • This will help determine the placement of the fasteners to attach the panels to.

  5. Measure each opening’s width from the inside of the exterior trim. (Figure D) Measure the opening’s height from the sill to the bottom of the top trim. When measuring a window with an extended sill, measure from the top of the sill to the bottom of the top trim.

  6. Write this information down on your worksheet along with a brief description of the opening. (Figure E)
