Understanding Your Window
Knowing the key parts of your window will help you measure accurately.
3. Window cavity
Your secondary glazing panels sits across this cavity to create an insulating air gap. Ensure any window furniture, such as handles or locks, fits comfortably within this space.
How To Measure
Accurate measurements ensure your panels fit perfectly.
- Measure the height on both sides (in cm & mm).
- Measure the width at the top and bottom (in cm & mm).
