Installation Instructions
New Construction Windows
Installation of Window
- Apply a generous bead of silicone caulking to all 4 sides of the nail fin in the location shown to the left. (typical for all new construction windows)
- Place the window in the opening and press it firmly against the wall to squeeze the caulking under the fin. Secure to the wall in a temporary fashion to allow for shimming and leveling of the frame.
- Shim under the window sill as needed to level the unit(s) in the opening, following the general guidelines shown to the right. Use tapered shims in pairs to create a parallel spacer. NOTE: Shimming under the center of operating windows in not recommended as it may cause a crown in the sill and impair the performance of the window.
- Next shim along the sides of the window to ensure there is no bow or twist in the window jambs. Check the function of the window throughout this step to maintain the smooth operation of the sashes.
- Complete the attachment of the window frame to the exterior sheathing of the house using nails or screws in the slotted holes on the nail fin.
