The Plaslyne External Window Cill End Caps are an essential finishing component for homeowners and contractors installing or renovating PVC window cills. Designed specifically for 180mm standard profiles, these caps provide a clean, professional appearance while sealing exposed edges against water ingress and debris, though they require precise measurement of your existing cill width to ensure a proper fit.

While designed for external use, they can technically be used indoors if the cill dimensions match, though they are specifically treated for external weather resistance.
Yes, this set includes a pair of end caps to cover both ends of a single window cill.
A standard PVC trim adhesive or a high-quality superglue (cyanoacrylate) designed for plastics is recommended for a permanent bond.
While they are white PVC, you can use specialized plastic primer and spray paint if you need to change the color, though we recommend maintaining the original finish.
These are designed for 'standard' 180mm PVC cills. If your cill has a non-standard shape or heavy decorative molding, the fit may not be flush.
Ensure that all debris and dust were removed from the cill edge before applying adhesive, then use a stronger PVC-specific solvent adhesive.
Verify that your cill is exactly 180mm and is a standard profile; if there is a burr on the cut end of the PVC, file it down until smooth.
Before installation, ensure the cut surface of your 180mm window cill is clean, dry, and free of dust or oils. Apply a thin bead of high-quality PVC-compatible adhesive or superglue to the interior rim of the end cap, then press firmly onto the cill edge until the adhesive sets. For maintenance, periodically wipe the caps with a soft cloth and mild soapy water to remove accumulated grime or pollutants. Avoid using abrasive cleaning agents or harsh chemicals which may scratch the PVC surface.
