Letter Box Covers for uPVC Doors
Our letter box covers for uPVC doors are designed to improve insulation, enhance security and give your entrance a clean, finished appearance. Fitted to the internal side of your uPVC or composite front door, a letter plate cover helps reduce draughts, minimise heat loss and prevent unwanted visibility through the letterbox opening — making it a practical upgrade for any home.
Manufactured specifically for compatibility with uPVC door constructions and telescopic letter plates, these covers are easy to fit and built for everyday use. They provide an additional internal barrier, helping to improve energy efficiency while maintaining smooth operation of the external letter plate.
Available in a range of finishes to coordinate with your existing uPVC door furniture, our letter box covers allow you to achieve a cohesive look inside and out. Whether you’re replacing a damaged component or upgrading for improved comfort and performance, they offer a simple, effective solution for modern uPVC doors.
