Measuring Size
The first step in replacing old PVC windows is measuring the dimensions of the old windows. Just like taking measurements before buying clothes, windows also need precise measurements. Key points to note:
Measure the width and height of the window frame, both inside and out, taking data from at least three different locations.
Record the thickness of the window frame to ensure the new window fits.
Check if the wall surface is flat to avoid gaps during installation.
Selecting Materials
Choosing PVC windows is like choosing a phone case; it needs to be both aesthetically pleasing and practical. Recommendations:
Frame Thickness: 60mm or thicker is recommended for better load-bearing capacity and sound insulation.
Glass Configuration: Double-glazed windows provide better insulation than single-glazed windows.
Hardware: High-quality pulleys and locks make the windows more durable.
Construction Details
The installation process is like surgery; every detail affects the final result. Pay special attention to:
Protect the wall surface when removing the old window to avoid secondary damage.
The new window must be installed horizontally and vertically; a level can be used to check.
The expanding foam should be applied evenly, and the sealant should be continuous without breaks.
After installation, check if the windows open smoothly and if the seal is tight.
