Installing Your Window(Follow Next Section for Storm Windows Installation)
Step1-Remove Old Window
Always wear safety goggles, gloves and face mask during removal and installation of windows.
Carefully remove inside trim, moldings, and/or stops with broad chisel, and save for later use.
Remove old cords and weights (or spring balances) from bottom sash and carefully remove from frame.
Pry out parting stops at top and sides to allow removal of top sash. Be sure not to damage existing stops or openings.
If existing window is fitted with aluminum tracks, remove securing staples, and remove both sashes and track
In Step 2-Clean and Prepare Opening
For Mechanical Windows, Casement Windows, or Slider Windows, install Sill angle on sill 1/8" behind Blindstop. For all Welded Windows, snap angle to bottom of window frame. See figure 1a.
Close and lock window sashes. Set new window in opening to verify all correct measurements. Remove window from opening.
Add a generous amount of caulk to the inside and outside edge of the stool. Also, add caulk to the outside blindstops and along the top of the opening's header.
If needed, place head expander on top of window and caulk along the top surface. A layer of insulation between the head expander and frame may be added if necessary. Expander legs may also be easily trimmed with a utility knife to accommodate various heights.
In Step 3-Install New COO Window
From the interior wall side, set window (be sure sashes are still locked) into openings and butt the exterior window frame up against the opening blindstops. For Mechanical Windows, do not cut black band until window is installed in opening.
Check the window for plumb and level. Add shims where necessary. It is highly recommended that shims be placed at the middle of the frame and at the middle of the top and bottom sashes. (See figure). Also, install shims behind screw holes to prevent screw tightening from warping frame.
Locate the pre-drilled screw holes on the sides of window frame. For Mechanical and Welded series, holes will be located at the top and bottom of both frames sides (oversize windows may also have pre-drilled holes in frame top). For Sliders, Casement windows and oversize windows, remove factory installed screw caps from top and sides.
Secure window to opening by installing screws (supplied) through the screw holes into the frame opening. Re-install screw caps.
If installing a head expander, raise expander until it is flush with top of opening. Drill pilot holes and secure to frame with small screws al lowest part of expander.
Replace inside stop (moldings) if necessary.
Install insulation around the entire window between the frame and opening. Be careful, installing too much insulation on top and bottom may cause window to bow.
Installing Storm Windows
Tools and additional supplies needed:
1/8" metal drill bit
Phillips bit for drill
Clear silicone, usage; ½ tube per window
Installation of these units is simple. They are self-contained and include through which the unit is attached to the existing window. During installation, apply caulk between the mounting flanges and the window to which they are mounted. Do not caulk the weep channel at the bottom of the unit. These "weep channels" allow condensation to escape.
As you install the units, make sure they are level and the frames are not distorted when the screws are mounted through the flanges. This will allow the sashes to move easily up and down the channels.
Clean, repair, and paint existing prime windows which are to receive storm windows before storm windows are installed.
Clean glass [, wood,] and metal surfaces which will be between the storm and prime windows with appropriate detergents or cleaning agents. Leave free of dirt, streaks, fingerprints, and other soil.
1. Install storm windows plumb, square, level, and in alignment and securely fastened to adjacent construction.
2. Make sure the window are the proper size.
3. Start by pre-drilling 1/8” holes through the mounting flange at the outer most line. Drill pattern is as follows, 3” in from each corner and 12” apart on all sides. Depending on the installation type, the bottom might only be drilled on the sides.
4. Caulk between perimeter of interior face of storm window frames and adjoining construction with silicone.
5. Set the window in place and install a screw at each corner. Mount one side plumb first then square the window.
6. Install bottom sill with weep channels
7. Make sure the vertical and horizontal frame is straight (use a level or straight edge) and apply the remaining screws.
8. Make sure the all sashes move freely in their tracks and lock properly. If not, make adjustments to the frame.
