Marvin Window manual Technical Installation Specifications

Technical Installation Specifications

The following details are specified for proper installation and for the unit to meet the advertised design pressure (DP) rating.

SRough Opening Width: 1/4″--1″(6--25)wider than window/door frame outside measurement.

SRough Opening Height: 1/4″--1/2″(6--13)higher than window/door frame outside measurement.

SMasonry Opening Width: 1/4″--1/2″(6--13)wider than window/door frame outside measurement.

SMasonry Opening Height: 1/8″--1/4″(3--6)higher than window/door frame outside measurement.

Architectural Detail Manual Specifications:

SRough Opening:Width 1″ (25); Height 1/2″ (13).

SMasonry Opening:Width 1/2″ (13); Height 1/4″ (6).

SIf 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.

SMarvin recommends the use of sloped sills on all concrete openings (either pre--cast or poured).

SRegarding 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.

SFor 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.

SProperly flash and/or seal all windows at the exterior perimeter.

SSealants 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.

SFlashing 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 The following materials were used to develop these instructions in the Continuous Air Barrier Systems section:

Weather Resistant Barriers: DuPontt Tyvek→ HomeWrap or Grade D building paper.

Flashing Materials: DuPontt FlexWrap or DuPontt Straight Flash, DuPontt Tyvek→ Tape.

Sealant: OSI→ Quad Pro--Series→; solvent release butyl rubber sealant or DAP DynaFlex230t.

Panning System: Marvin SillGuardt.

Other materials may be used but must be compatible with one another. Refer to each product’s technical specifications for compatibility and usage.

SOptional foams used for installation must be low expansion only. Foam and foam application must comply with ASTM E2112--01, SEC 5.9.2.

SShims 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.

SFor units with flat casing install with installation brackets, structural masonry brackets, or jamb screws.

SDo not use chemically treated products for shim material.

SFasteners penetrating chemically treated lumber must be a minimum of 0.90 oz/ft2 zinc hot dipped galvanized or stainless steel type 304 or 316.

SClad window frames must not come into direct contact with chemically treated wood products.
