Alliance New Construction Window Installation

Preparing the Opening

  • Before installation, read instructions thoroughly and be sure window is closed and locked. Make sure window opening is free from any dirt or debris. In order for the caulk to work properly both surfaces must be clean and dry.
  • Apply a bead of high-performance caulk (within 3/8” from the edge) around the exterior perimeter of the window opening. This becomes the primary seal between the window and the building.

Installing the Window

  • Lift and place the window into the rough opening, use the proper help and/or equipment needed to install window properly and safely.
  • Place the sill on shims located on the sill plate. Press the window firmly into the caulk and loosely fasten one of the upper corners.
  • Check the sill for level, shim as necessary at the jamb ends. Check the frame for plumb and the jambs for straightness, shim as necessary.
  • Open the sash and close it almost to the sill (SH, DH) or jamb (Gliders). Insure that there is an even gap or margin between the sash and the frame, and that the sashes are square with the frame.
  • Verify squareness by checking diagonal measurements.
  • Fasten the window frame to the rough framing through the center of the slots in the nail fin. DO NOT OVER NAIL FINS, fins should be parallel with sheathing. Over nailing can twist jambs and impair sash operation. The frame should remain straight ad not bow. This will prevent problems with sashes operating correctly.
  • Cover nail fin with 4-6” width of ice and water shield or similar product to further prevent water penetration.

Important: For brick applications allow a minimum of 1/4″ between the frame and brick for expansion and settling.

Alliance Replacement Window Installation

Important: Measure new window before removing old one.

Wood Removal

  • Depending on existing window style, remove sash and balance system (Pulley, jamb, liner, etc.).
  • Remove inside stops. Score first with razor knife and use special care in removal if the existing inside stops are to be reinstalled.
  • Cut cords and remove lower sash.
  • Remove parting stops and remove upper sash.
  • Clear opening of all old balance hardware.

Installation Procedures

  • Head, sill and jambs must be free and clear of protruding objects (nails-pulleys).
  • Properly clean the opening of dirt and debris.
  • Install head expander and sill leg if necessary and where they apply. Caulk the blind stops and insulate sill.
  • Position window in opening with sash locked and compress it tightly against the caulked stops and sill.
  • Plumb, square and level window in opening so that sashes are square with the main frame.
  • Run all four installation screws until just snug, first the top two, then the bottom two, centering the frame from side to side and checking to be sure the frame remains square. Temporarily shimming each corner as you run the screws helps to keep the frame centered and square.
  • Using jamb adjusters or wood shims make sure each jamb is straight and the main frame measures the same at the opening at the top, middle and bottom. Insulate around frame at jamb and head.
  • Check window for proper operation, locking and fit. Make adjustments as necessary.Download Installation Instructions



Prepare The Opening.

  • Allow for clearance of at least 1/4” on either side of rough opening and 1/2” above the head jamb.
  • Make sure the floor is level.
  • Before you set the door in the opening, apply a high-grade sealant in two parallel strips along the length of the sub-floor from one side of the opening to the other. Also run a 3/16” bead of sealant (formulated to adhere to vinyl) around the perimeter of the rough opening.

Installing The Door.

  • Remove all packaging material from the door.
  • With the operable sash removed, set the bottom of the doorframe onto the sill plate and gently tilt it until the nailing flange is secured against the sheathing. Make sure the doorframe is properly centered.
  • Insert a temporary screw through the nail fin at the top of the doorframe to hold the door in place.
  • Make sure that the door frame is level and that the side jambs are plumb and square.
  • Place three sets of wood shims along each side of the doorframe between the jamb and the rough opening. Align at least one shim with the strike plate on the latch side of the jamb. Secure the doorframe into the rough opening making certain to maintain square and level positioning of the door. Do not over tighten or distort jambs.
  • Check again for level and square installation.
  • Set operating panel into the doorframe and make necessary adjustments to rollers to maintain equal height and smooth operation of the operable sash.
  • Close the door panel and adjust the shims to maintain uniform spacing between the operable sash and the doorframe all the way up and down the jamb. Also check that the operating clearance between the door panel and the head frame is uniform. Adjust with shims or adjust the panel rollers if necessary.
  • Remove the temporary keeper screws and replace with the 3” screws provided making certain to screw into the wood framework of the rough opening.
  • Fasten the door with an adequate number of nails around the exterior nailing flange (nail every 12”). Cover the nailing flange with a building wrap tape to insure air and water tightness.
  • Insulate between frame and rough opening with fiberglass insulation.DO NOT USE EXPANDING FOAM INSULATION.
  • Proceed with interior and exterior finish.
