Setup, Compatibility & Care
To use, identify the gap between the window frame and the wall aperture. Select the appropriate colour-coded packer that provides a snug fit without forcing the frame out of alignment. For larger gaps, you may combine multiple packers, provided they are placed securely and do not interfere with fixing points.
Compatibility: These packers are designed to work with all standard uPVC, aluminium, and timber frames.
Care: Being made of Polypropylene, they require no maintenance. However, ensure that any excess sealant used during installation does not bridge the gap in a way that prevents drainage. If removing old frames, check that these packers are not damaged or crushed before reusing them for temporary leveling tasks.
