JELD-WEN JMI002 Double-Hung Sash Replacement Kits - Manual

MEASUREMENT GUIDE
for Double-Hung Sash Replacement Kits (JMI002)
Thank you for choosing a JELD-WEN Wood or Clad Wood Double-Hung Sash Replacement Kit. Please read this document fully before beginning.
Consult your local building code official for applicable codes and regulations (particularly regarding minimum egress requirements). The installation
of a replacement window will not eliminate installation or maintenance problems with an existing window. Problems such as wood decay and
water leaks around the existing frame must be investigated and fixed prior to installing replacement sashes. Windows produced to user specified
dimensions cannot be returned. Be sure the provided measurements are correct.
• A minimum 3 3/8" wide jamb depth (“opening”) must exist for
replacement jamb liners).
• If the existing window sill is not level, or if the existing window is not
square and plumb, installation may be complicated and additional trim
work may be needed during installation. Consider professional installation
assistance.
• Use the worksheet on the back to record measurements for each window
to be replaced. Use additional copies as needed for more windows.
• Record each window’s location in the house on the worksheet in a manner
that clearly identifies it.
• If there is more than 1/8" deviation within each set of measurements,
investigate the cause and seek professional assistance to correct problems.
• Perform all measurements on each window before going to the next
window.
• Individually measure each existing window to be replaced. Do not assume
similar looking windows are exactly the same size.
• Measure accurately, to the nearest 1/8".
IMPORTANT INFORMATION
• Measure the width between
the side jambs (wood surface to
wood surface) in three places:
top, middle and bottom.
• Temporarily remove jamb
liners if necessary and avoid
any stops, weatherstrip,
balance cords, pulleys, etc.
• Record your measurements.
MEASURE THE WIDTH
1
CONFIRM SQUARENESS
OF EXISTING WINDOW 3
• Confirm the existing
window is square by
measuring both diagonals.
If the two diagonal
measurements differ by
more than 1/4", an out-of-
square adjustment in the
width of the window must
be made.
• The adjustment is
determined by creating
a plumb line (using a
level) from each corner to
the sill or head. Using a
plumb line that falls within
the window opening,
measure the out of square
adjustment.
• Subtract this measurement
from the smallest width
measurement. Record
this adjusted width as the
smallest width.
MEASURE THE HEIGHT
2
• Slightly open both sashes
and thread the tape measure
between the sashes.
• At the top, measure directly
from the head jamb, avoiding
any stops, weatherstrip and
liners.
• At the sill, measure to the
top of the sloped sill on the
exterior side of the lower sash.
• Measure the height at the left
side, middle and right side.
• Record your measurements on
the attached worksheet.
