StyleView® Flange Hung and Fixed Window Installation Instructions
For Flange Hung and Fixed Windows
READ THE QUICK GUIDE BELOW OR DOWNLOAD THE FULL INSTRUCTIONS HERE
STEP 1: Prepare the Opening
Note: Installation of fixed picture windows with flanges is the same as that for single hung, except for operation of moveable window sashes that are not on fixed windows.
- Ensure the rough opening is 1/2” larger than the window to be installed and that the rough opening is plumb and square. See Detail 1.
Note: The frame size of the window does not include any protruding flanges.
- Close and and lock the sash(es) to help keep the unit square.
- Place the sill anchor plate on the pre-cast sill, and position it approximately 5/16” back from the outside edge of the buck. Shim to level if necessary and secure the sill anchor plate to the pre-cast sill with #10 x 2” Tapcon® masonry fasteners. See Detail 2.
- Apply a continuous bead of silicone caulk to the perimeter of the rough opening where the nail fin will make contact (at the edge of the rough opening.) Leave two 3” gaps for weepage at the sill flashing as shown.
STEP 2: Install the Window
- Set the window into the opening from the outside so that the flange makes contact with the outside surface of the wood buck and pre-cast sill. See Detail 3. Make sure the sill anchor plate interlocks with the bottom of the window to assure integrity of the sill under negative and positive pressure. See Detail 4.
- Center the window in the opening and check to make sure it is plumb and square. Take diagonal measurements to ensure the unit is square. Opening the bottom sash of the double hung window approximately 1/4” will provide visual confirmation of proper setting, that the reveal between the frame and sash (A & B) are equal the entire width. See Detail 5.
- Shim as required between the rough opening and the window frame at every installation hole locations.
- Secure the window in the opening through the pre-drilled holes in the head and jambs using fasteners. To access the installation screw holes, use a putty knife to remove the snap-in cover or screw track cover as shown in Detail 6. Replace the covers after the screws are set. All fasteners must have a minimum 1-1/2” penetration into the masonry.
STEP 3: Finishing
- From the exterior, caulk along the flange of the window to ensure a watertight seal as shown in Detail 6.
- Operate the window (for single or double hung) to confirm proper installation.
- Apply fiberglass insulation to the cavity between the window and rough opening structure.
- From the inside of the window, apply continuous sealant to the interior perimeter of the window sill and 12” up the jambs as shown in Detail 7.
- Do not use expanding or spray-in foam products. If the installer used one of them, make sure jambs remain straight to ensure the operation of the window is not impeded.
- If using brick or stone exteriors, leave a 1/8” gap from the window to allow for brick and mortar expansion. Use a backer rod and silicone caulk to seal the gap.
- Do not use brick wash after windows are installed. Doing so will void the window warranty.
- Windows should never be stored in an area where temperatures will exceed 140° F. Doing so will void the window warranty.
- Windows should never be painted. Doing so will void the window warranty.
