Technical Installation Specifications

The following details are specified for proper installation and for the unit to meet the advertised design pressure

(DP) rating.

S If using less than a nominal 2, x buck in masonry

openings; the rough opening must be no more than

1/2,

(13)

wider and 1/4,

(6)

taller than the outside

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 in direct contact with

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.

S Properly flash and/or seal all windows at the exterior

perimeter.

S Sealants used for installation must be Grade NS Class 25

per ASTM C920 and compatible with the building exterior,

window exterior surface, and flashing/water management

materials.

S Flashing materials must comply with ASTM E2112−01,

section 5.13 and be compatible with all materials used in

installation including panning systems, air barriers and

building papers, sheathing, and the window unit.

Flashing material must not contain asphalt and must

be compatible with flexible PVC (vinyl) when used in

conjunction with nailing fin.

S Optional foams used for installation must be low expansion

only. Foam and foam application must comply with ASTM

E2112−01, SEC 5.9.2.

S Shims are required between the window frame and framing

members at all locking points and at every point of

attachment (excluding nailing fin and brick mould casing)

as well as at all points detailed within these instructions.

zinc hot dipped galvanized or

S Rough Opening Height: 1/4,−1/2,

(6−13)

higher than

window/door frame outside measurement.

S Masonry Opening Width: 1/4,−1/2,
