Replacement Window Application

Unpackage window and check to insure the following items are included:

(2) 2 1/2" Flathead Screws for Hinge
(4) 2" Installation Screws
(1) Handle

  1. Measure New Window For Squareness
    Measure window unit width and height to insure correct size. Measure frame and sash diagonally from corner to corner. Each measurement should not exceed 1/16" difference.
  2. Check Rough Opening
    Verify rough opening size against actual window size to insure correct fit. Check rough opening for squareness by measuring diagonally from corner to corner.
  3. Removal Of Old Window - Preparing The Opening
    Remove the old window along with any obstructions which may exist in the opening. Remove all dirt and debris and fill all voids with insulation.
  4. Sill Preparation
    It is very important that the sill of the opening be flat and level. The sill must also be a minimum of 3 1/4" wide to support the casement window frame. It may be necessary to replace a sloped sill to insure that your sill will accommodate the casement window frame.
  5. Visible Check For Squareness And Adjustments
    Position window in opening to insure window is square and level. It may be necessary to shim window to achieve squareness. A visible check would be to examine the perimeter of the exterior flap seal. There should be a consistent space between the frame and the sash around the entire perimeter of the window. Once you are confident the window is square and the sash/frame relationship is correct, remove the window and permanently secure the shims.
  6. Caulk
    Caulk against any stops being used and place the window tightly against the caulk.
  7. Secure The Window
    Open the sash. Secure the window by installing the four 2" installation screws into the side of the frame.
    Locate the screws 4" from the top and bottom of each jamb and screw into the sash track.
    (See Illustration, Point Z)
      1. Casement windows 48" or taller require one additional installation screw (enclosed) located in the center of both side jambs.
      2. Mulled units require additional installation screws (enclosed) located 4" on either side of mullion in the head.
      3. Awning windows 44" or wider require one additional installation screw located in the center of the head.
  8. Check Operation
    Check the window operation a few times to insure that the sash closes smoothly into the frame, all locks operate correctly and there is a consistent space between the sash and the frame. (Some silicone spray may be needed on the exterior flap where the flap comes in contact with the mainframe.) Again check for squareness and place additional shims if necessary.
  9. Remove Hinge Screws
    For additional strength, replace screws located closest to the hinge jamb in head and sill of master frame with 2 1/2" flat head screws provided. Replace screw with 2 1/2" flat head screw with 2 1/2" screw provided. (See Illustration)


New Construction Application

  1. It is necessary that the window be installed plumb, level and square to insure proper performance and achieve compliance with manufacturer's warranty.
  2. Close and lock sash before installing window.
  3. Using a premium grade exterior silicone caulk, caulk the inside of the window fin where the fin will contact the rough opening.
  4. Center and level window opening. Nail one top corner (1 3/4" roofing nails are recommended.) Then nail opposite corner making sure the window top is level. This will hang window to help assure unit is plumb, level and square.
  5. Shim window side jambs properly locating shims to minimize deflection of the frame. Use shims under frame jamb at sill to square window as required.
  6. Complete installation by nailing every other hole from top down.
  7. Use fiberglass insulation (or equal) to fill all perimeter voids. (Do not use expandable foam insulation because of the possible chance for frame distortion which could impede proper operation of unit.)
  8. Flash the exterior of window to preclude entry of water into wall cavity.
  9. Caulk the exterior perimeter between window frame and trim.
