INSTALLATION

Installing Vinyl New Construction Windows

 

  • Check to be sure rough opening is proper size and sill plate must be level.
  • It is advisable to staple building paper over the edges of the rough openin, as shown. Put the bottom strip on first, and the sides next. The top strip is mounted after the window is installed and overlaps the top nailing flange. This will direct water away from window opening.
  • It is important to seal the nailfin or brickmold to the sheathing by applying a 3/16” continuous bead of caulk to the back side of the nailfin or brickmold prior to placing the unit in the rough opening
  • Do not nail the flange tight. Like siding, nailling must be just tight enough to hold the window, but do not impede movement of the structure underneath during environmentally caused expansion and contraction.
  • Shim under sill as required to maintain flat and level sill.
  • Check squareness of the frame by measuring diagonally from corner to corner. Unit is square when measurements are equal.
  • After installation, caulk around frame as required to ensure weather tightness. Insulate the cavity between the frame and the rought opening of the wall, without distorting the frame.

Note: Expanding foam should not be used.

Building Code Considerations

Due to varied State and Local Building Codes, it is the sole responsibility of the individual purchaser, and/or contractor/builder to ensure the windows/doors comply with existing building codes. I.E. Ingress-Egress requirements, safely glazing requirements, and location of the products. Please contact your Local Building Codes Offical.

Note: Brick Mason / Siding Contractor

  • Provide minimum clearance of 1/2” from brick or masonry veneer to bottom of window/door unit.
  • Failure to provide adequate clearance could result in sill bowing and improper unit performance.
  • Thoroughly rinse brick cleaning solutions from the unit with clear water. Acid solutios used to clean masonry can damage the glass, fasteners, frame and hardware.

Installing Vinyl Replacement Windows

Note: Check your new windows for correct size before removing your old window

Preparation

  • Remove inside trim. Score with a razor knife and use special care in removal and not if the existing trim is to be installed.
  • Cut cords and remove lower sash.
  • Remove parting stop, cut cord and remove upper sash.
  • If you have a window with aluminum track, remove stables on both sides and track and sash will remove as a unit.

Preparation

  • When installing screws, do not overtighten them as it will pull the frame out of line. Tighten screws just snug against the vinyl.
  • Fill the still angle with with its large leg up and short leg beneath the window.
  • Temporarily hold the window in the the opening to determine whether or not the top expander channel is needed. If window fits snugly top to bottom, the top expander may be removed or trimmed before installation for a better fit.
  • Apply a liberal caulking bead along the inside of the blind at the top and both sides where the window frame will make contact. Also apply caulking beneath the sill angle.
  • Position the window into the opening. Determine if any wood shims are needed to keep the window plumb, square and centered in the opening.
  • Raise the bottom sash up to the sash stops. Install a screw into the jamb at each side in the installation holes located under the sash stop at the bottom of the window. Make screws snug; not to tight.
  • Lower the top sash down to the sash stop. Install a screw into the jamb at each side of the top of the window. Make screws snug; not too tight.
  • The window musht be centered and squared in the opening! Check to be sure the window frame is square and adust installation screws if necessary.
  • Check the center of the window for adjusting the jamb adjusters located there. Do not remove the sashes during the adjusting operation as they will maintain proper spacing between jambs.
  • The jamb adjusting screws (Fig. A) are located at the middle on both sash stacks on both sides of the window. Turning the screws in a clockwise direction will cause the jamb middles to “pull” toward the center of the window.
  • In extreme cases, the old wooden window maybe badly “bowed.” If the adjustments do not solve this problem, wood shims will have to be used between the rough opening and the replacement window jambs.
