Impact windows are a crucial addition to homes in storm-prone areas. They provide an extra layer of protection against high winds and flying debris.
This guide will walk you through the process of installing impact windows. From gathering the necessary tools to sealing the window, we’ve got you covered.
Whether you’re a DIY enthusiast or a homeowner looking to save on installation costs, this step-by-step guide is for you.
Understanding Impact Windows
Impact windows, also known as hurricane windows, are designed to withstand severe weather conditions. They are made from laminated glass and have a special layer of polyvinyl butyral (PVB) in between.
This design allows the window to resist high winds and impacts from flying debris. Even if the glass breaks, the PVB layer holds the pieces together.
Installing impact windows can significantly increase your home’s safety and potentially lower your insurance costs.
Tools and Materials Needed
Before you start the installation process, gather all the necessary tools and materials. This will make your work easier and more efficient.
The basic tools you’ll need include a tape measure, level, utility knife, caulking gun, and a drill.
Here’s a list of materials you’ll need:
- Impact windows
- Flashing tape
- Waterproofing membrane
- Caulk
- Screws
- Shims
Ensure you have all these items before you start the installation.
Preparing the Window Opening
The first step in the installation process is preparing the window opening. This involves measuring the opening to ensure the new window will fit.
Use a tape measure to get the height and width of the opening. Make sure to measure from the inside of the opening.
Next, check the opening for any damage or rot. Repair any issues before proceeding with the installation.
Removing the Old Window (If Applicable)
If you’re replacing an old window, you’ll need to remove it first. Start by removing the trim and any other attachments.
Next, carefully remove the old window from the frame. Be cautious to avoid damaging the surrounding area.
Dispose of the old window responsibly, following local waste disposal guidelines.
Installing the New Impact Window
Now that the opening is ready, it’s time to install the new impact window. Start by placing the window in the opening.
Ensure the window fits snugly in the opening. If it doesn’t, you may need to adjust the size of the opening.
Once the window fits, secure it temporarily with shims. This will keep the window in place while you work.
Checking for Level and Plumb
Use a level to check if the window is perfectly horizontal. Adjust the shims as needed until the window is level.
Next, check for plumb. This means the window should be perfectly vertical. Again, adjust the shims as necessary.
Securing the Window Frame
Once the window is level and plumb, secure the frame. Use screws to attach the frame to the house structure.
Ensure the screws are tight, but be careful not to overtighten. Overtightening can warp the frame.
Sealing and Attaching the Window
Apply a bead of caulk around the window frame. This will create a seal and prevent air and water from entering.
Next, attach the window to the frame. Use screws to secure the window in place.
Finally, apply another bead of caulk around the window. This will ensure a tight seal and complete the installation.
Final Steps and Cleanup
After the window is installed, test its operation. Open and close the window to ensure it operates smoothly.
Next, clean up your workspace. Dispose of old materials and clean any excess caulk from the window.
Finally, inspect your work. Make sure the window is secure, operates correctly, and looks good.
When to Hire a Professional
If you encounter issues during installation, consider hiring a professional. They have the skills and experience to handle complex installations.
Also, for large or high windows, professional installation is safer and more efficient.
