What Is a New Construction Window?
New construction windows are installed directly onto the frame of a home, as opposed to into an existing window opening. They are equipped with a nail fin or flange, enabling the unit to be securely anchored and sealed. This is the preferred method for new construction, room additions, or large renovations when studs are exposed in the walls.
Tools & Materials You‘ll Need
Before you start the installation process, make sure you have the following:
- Tape measure
- Level
- Hammer or nail gun
- Utility knife
- Flashing tape
- Caulking gun & silicone sealant
- Insulation (low-expansion foam)The window unit (INSPIRE VINYL PW 1050 – Picture Window)
Step-by-Step: How to Install New Windows
Prepare the Rough Opening
- Verify window size with the rough opening.
- The opening must be 1/2″ larger than the window unit.
Install Flashing Tape
- Line the sill with flashing tape, overlapping edges.
- Form a water-resistant barrier.
Dry-Fit the Window
- Install the window in the opening to ensure a fit.
- Adjust as necessary prior to sealing.
Apply Caulk & Insert Window
- Apply silicone caulk to the back of the flange.
- Carefully insert the window into the opening.
Secure the Window
- Nail through flange into framing.
- Use a level to verify proper alignment.
Insulate & Seal
- Filling in gaps with low-expansion foam insulation.
- Use exterior flashing tape over nailing fins.
Final Inspection
- Check to make sure the window opens easily.
- Test for air and water leakage.
Common Mistakes to Avoid
- Missing flashing: Caused by water penetration.
- Over-tightening of fasteners: Warps the frame.
- Misalignment: Causes binding or leaky seals.
- Incorrect window size: Measure twice before ordering.
