Technical Installation Specifications

The following details are specified for proper installation and for the unit to meet the advertised design pressure
(DP) rating.
S Rough Opening Width: 1/4"−1"
window/door frame outside measurement.
S Rough Opening Height: 1/4"−1/2"
window/door frame outside measurement.
S Masonry Opening Width: 1/4"−1/2"
window/door frame outside measurement.
S Masonry Opening Height: 1/8"−1/4"
window/door frame outside measurement.
Architectural Detail Manual Specifications:
S Rough Opening:Width 1"
S Masonry Opening:Width 1/2"
S If using less than a nominal 2" x buck in masonry
openings; the rough opening must be no more than
1/2" wider and 1/4"
(13)
measurement of the frame. Installation methods are
limited to Jamb Screw method using 3/16" concrete
screws.
S Marvin recommends the use of sloped sills on all concrete
openings (either pre−cast or poured).
S Regarding recessed masonry openings: the window
frame must not come
masonry/concrete/concrete block. Construct framing
from treated lumber or plywood and fasten to the masonry
opening jambs, header, and sill. This framing must be
designed (and anchored to the opening) properly to
withstand certified and advertised DP ratings for your
particular unit.
S For installations in typical wood frame construction (with
sheathing and building paper or air barrier material)
where a continuous air barrier system is used, refer to
ASTM E2112−01 or reference the "Continuous Air
Barrier Systems" section for details on preparing the
rough opening and sealing the installation.
S For installations in concrete block, or masonry
construction, etc., follow local codes for sealing and water
management details.
Be aware that the use of rigid sill pans and
other barriers will decrease the rough
opening height clearance. Adjust opening
dimensions accordingly.
WARNING: Drilling, sawing, sanding or
machining wood products generates wood
dust, a substance known to the State of
California to cause cancer. Avoid inhaling
wood dust or use a dust mask or other
safeguards
