About Upvc Door Seal

uPVC is a rigid, unplasticised PVC. Its resistance to damage by sunlight or rain and ease of maintenance make it particularly suitable for the frames of exterior doors or windows. uPVC doors are typically supplied as a complete unit which includes rubber seals or gaskets to exclude draughts and moisture. Rubber can perish over time, so you may need to replace these gaskets to improve weather resistance. uPVC door seals come in a range of styles. A 'wedge gasket' is used to seal the joint between the pane and the frame in some glazed uPVC doors, and these come in a range of sizes. An 'E' gasket performs a similar function. This more complex style can vary in both size and shape. Subject to more wear and tear and therefore much more likely to need replacing is the seal between the outer edge of the door and the door frame. These gaskets come in two basic styles: bubble or flipper. A bubble gasket is designed around an enclosed tube of air designed to create a flexible seal. These also come in a range of sizes and designs. The flipper type creates a seal using the natural spring of a v-shaped cross-section. It should be fairly easy to distinguish which of these four types you need. If in doubt, look at the end or cut a slice from the seal you need to replace. Within the types it's more difficult to choose. Check your windows specs, and if you don't have that information, it may be helpful to start with a sample pack. Patio doors often use a U-channel gasket in the frame, which creates a wrap-around seal for the door. These tend to follow the same basic design, but check dimensions before you buy.
