New Construction Double Hung Window Installation Instructions

The following must be done to insure warranty coverage. All vinyl new construction windows are designed to be installed plumb, square and level. If the installer does not meet these simple requirements, the appearance, operation and weatherability of the unit will be affected.

A bead of caulk should be placed around the opening within 1/4" of the edge. Center window in the opening, there should be approximately 1/4" -3/8" space on both sides between opening and window, firmly seating it into the caulk. Partially secure one top corner with nail in pre-drilled hole. Do not fully set nail all the way.

Verify unit is plumb, level and square (See Figure 2) . If needed use wood shims to ensure window is level and square. Do not over shim. * For mulled units, make sure to shim underneath each mull. Attach nail to other upper corner.

Check sash for easy operation; close and lock window. The check rails will align if unit has been installed plumb and square. Unit will not operate smoothly if not square or over-shimmed Complete installation on the outside by driving 1 3/4" galvanized roofing nails all around perimeter, in every other slot.

Cover the cut edges of the rough opening with 9" strips of flashing paper or other moisture resistant flashing such as Tyvek, building tape, etc. Staple or nail into place. Put bottom strip on first leaving bottom edge of paper loose so building paper can be slipped under it later. The side strips are applied, overlapping the bottom strip and extending 6" above the window opening height and the top strip of flashing paper, after the window is installed and over the nailing fin. (See Figure 1)

Fill in any cracks between sides of unit and existing casing with fiberglass insulation (or non-expanding, low pressure foam insulation).

Apply exterior siding, stucco, brick, etc. Allow sufficient clearance around perimeter of windows. Caulk around entire perimeter of window unit and under sill.
