Measuring and Ordering Storm Windows
- Then measure the Height at left, center, and right.
**Note: Sloped sills require measuring to the point where the window frame will meet
the sill, not to the outside edge of the sill. Measuring to the outside edge of the sill will
result in too large of a window. Also, for the same reason, do not use the
measurements of a wood storm window that is being replaced.
- Order the narrowest Width and Height from the above measurements.
- Specify order size (Width x Height) after rounding down to the nearest 1/8".
- When ordering uneven glass insert heights (Oriel), specify the measurement
from the top of the window to the center of the meeting rail (TCMR).
Order one of the following manufacturing specifications:
EXACT (Tip To Tip): We will manufacture the storm window to your
exact measurements. Tip to Tip includes the fin.
BLINDSTOP (BS): If you give us an exact size of the existing window
opening, we will deduct 1/8" in Width and 1/8" in Height. This will
allow an inside mount to rest against the blindstops and on the sill.
OVERLAP: If you give us an exact size of the existing window opening, we
will add 1" to the Width and 1" to the Height. This will allow for an
outside overlap mount that mounts against the casing and on the sill.
Indicate the type of bottom expander. Expanders provide approximately 1/2"
No Expander: The window will be made to the size ordered above with
1" Expander (standard): One inch will be subtracted from the window frame
height; the size of the window including the expander will match the
measurements ordered above. This will give you about 1/2" addition on height.
2" Expander: One and one-half inches will be subtracted from the window
frame height; the size of the window including the expander will
match the measurements ordered above. This will give you about 1" addition to height.
